Human height or stature is the distance from the bottom of the feet to the top of the head in a human body, standing erect. It is measured using a stadiometer,{{cite web|title=Stadiometers and Height Measurement Devices|url=https://www.stadiometer.com/|website=stadiometer.com|access-date=6 June 2014|archive-url=https://web.archive.org/web/20181010180956/http://www.stadiometer.com/|archive-date=10 October 2018|url-status=dead}} in centimetres when using the metric system or SI system,{{cite web|title=Using the BMI-for-Age Growth Charts |url=https://www.cdc.gov/nccdphp/dnpa/growthcharts/training/modules/module1/text/page6bmetric.htm |website=cdc.gov |publisher=Centers for Disease Control |access-date=5 July 2014 |url-status=dead |archive-url=https://web.archive.org/web/20140130012800/http://www.cdc.gov/nccdphp/dnpa/growthcharts/training/modules/module1/text/page6bmetric.htm |archive-date=30 January 2014 |df=dmy }}{{cite book|author=Price, Beth|title=MathsWorld Year 8 VELS Edition|date=2009|publisher=MacMillan|location=Australia|page=626|url=https://books.google.com/books?id=t2veDRPjMggC|display-authors=etal|isbn=978-0-7329-9251-4}} or feet and inches when using United States customary units or the imperial system.{{cite book|author1=Lapham, Robert |author2=Agar, Heather |title=Drug Calculations for Nurses|date=2009|publisher=Taylor & Francis|location=USA|page=223|url=https://books.google.com/books?id=J1_vAgAAQBAJ|isbn=978-0-340-98733-9 }}{{cite book|last1=Carter|first1=Pamela J.|title=Lippincott's Textbook for Nursing Assistants: A Humanistic Approach to Caregiving|date=2008|publisher=Lippincott, Williams & Wilkins|location=USA|page=[https://archive.org/details/lippincottsworkb00pame/page/306 306]|url=https://archive.org/details/lippincottsworkb00pame|url-access=registration|isbn=978-0-7817-6685-2}}

In the early phase of anthropometric research history, questions about height measuring techniques for measuring nutritional status often concerned genetic differences.{{Cite journal|last1=Baten|first1=Joerg|last2=Matthias|first2=Blum|date=2012|title=Growing Tall: Anthropometric Welfare of World Regions and its Determinants, 1810-1989|journal=Economic History of Developing Regions|volume=27|doi=10.1080/20780389.2012.657489|s2cid=154506540|via=ResearchGate}}

Height is also important because it is closely correlated with other health components, such as life expectancy. Studies show that there is a correlation between small stature and a longer life expectancy. Individuals of small stature are also more likely to have lower blood pressure and are less likely to acquire cancer. The University of Hawaii has found that the "longevity gene" FOXO3 that reduces the effects of aging is more commonly found in individuals of small body size.{{cite web |title=Shorter men live longer, study shows |url=https://www.sciencedaily.com/releases/2014/05/140509110756.htm}} Short stature decreases the risk of venous insufficiency.{{cite web |title=Tall height |url=https://www.nlm.nih.gov/medlineplus/ency/article/000203.htm}}

When populations share genetic backgrounds and environmental factors, average height is frequently characteristic within the group. Exceptional height variation (around 20% deviation from average) within such a population is sometimes due to gigantism or dwarfism, which are medical conditions caused by specific genes or endocrine abnormalities.Ganong, William F. (2001) Review of Medical Physiology, Lange Medical, pp. 392-397, {{ISBN|0071605673}}.

The development of human height can serve as an indicator of two key welfare components, namely nutritional quality and health.{{cite book|author=Baten, Jörg |title=A History of the Global Economy. From 1500 to the Present.|date=2016|publisher=Cambridge University Press|isbn=978-1-107-50718-0}} In regions of poverty or warfare, environmental factors like chronic malnutrition during childhood or adolescence may result in delayed growth and/or marked reductions in adult stature even without the presence of any of these medical conditions.

Determinants of growth

The study of height is known as auxology.Hermanussen, Michael (ed) (2013) Auxology – Studying Human Growth and Development, Schweizerbart, {{ISBN|9783510652785}}.

Growth has long been recognized as a measure of the health of individuals, hence part of the reasoning for the use of growth charts. For individuals, as indicators of health problems, growth trends are tracked for significant deviations, and growth is also monitored for significant deficiency from genetic expectations. Genetics is a major factor in determining the height of individuals, though it is far less influential regarding differences among populations. Average height is relevant to the measurement of the health and wellness standard of living and quality of life of populations.{{Cite journal | last1 = Bolton-Smith | first1 = C. | title = Accuracy of the estimated prevalence of obesity from self reported height and weight in an adult Scottish population | doi = 10.1136/jech.54.2.143 | journal = Journal of Epidemiology & Community Health | volume = 54 | issue = 2 | pages = 143–148 | year = 2000 | pmid = 10715748 | pmc = 1731630}}

{{anchor|Growth Spurt}}Humans grow fastest (other than in the womb) as infants and toddlers, rapidly declining from a maximum at birth to roughly age 2, tapering to a slowly declining rate, and then, during the pubertal growth spurt (with an average girl starting her puberty and pubertal growth spurt at 10 years{{cite web |title=Early Puberty in Girls |url=https://www.nationwidechildrens.org/conditions/early-puberty-in-girls |website=Nationwide Children's |access-date=5 June 2020}} and an average boy starting his puberty and pubertal growth spurt at 12 years{{cite web |title=Early Puberty in Boys |url=https://www.nationwidechildrens.org/conditions/early-puberty-in-boys |website=Nationwide Children's |access-date=5 June 2020}}{{cite web |title=Is Your Child Growing Normally? |url=https://www.magicfoundation.org/Is-My-Child-Growing/ |website=THE MAGIC FOUNDATION |access-date=20 June 2020}}), a rapid rise to a second maximum (at around 11−12 years for an average female, and 13−14 years for an average male), followed by a steady decline to zero. The average female growth speed trails off to zero at about 15 or 16 years, whereas the average male curve continues for approximately 3 more years, going to zero at about 18−19, although there is limited research to suggest minor height growth after the age of 19 in males.{{Cite journal |last1=Hulanicka |first1=B. |last2=Kotlarz |first2=K. |date=1983 |title=The final phase of growth in height |url=https://pubmed.ncbi.nlm.nih.gov/6638938/ |journal=Annals of Human Biology |volume=10 |issue=5 |pages=429–433 |doi=10.1080/03014468300006621 |issn=0301-4460 |pmid=6638938}} These are also critical periods where stressors such as malnutrition (or even severe child neglect) have the greatest effect.

Moreover, the health of a mother throughout her life, especially during her critical period and pregnancy, has a role. A healthier child and adult develops a body that is better able to provide optimal prenatal conditions. The pregnant mother's health is essential for herself but also the fetus as gestation is itself a critical period for an embryo/fetus, though some problems affecting height during this period are resolved by catch-up growth assuming childhood conditions are good. Thus, there is a cumulative generation effect such that nutrition and health over generations influence the height of descendants to varying degrees.

The age of the mother also has some influence on her child's height. Studies in modern times have observed a gradual increase in height with maternal age, though these early studies suggest that trend is due to various socio-economic situations that select certain demographics as being more likely to have a first birth early in the mother's life.[http://www.nature.com/ejcn/journal/v57/n1/fig_tab/1601508t1.html#figure-title Table 1.

In 1988, it was observed that first-born males were shorter than later-born males.{{Cite journal| doi = 10.1080/03014468800009581| last1 = Hermanussen | first1 = M.| last2 = Hermanussen | first2 = B.| last3 = Burmeister | first3 = J.| title = The association between birth order and adult stature| journal = Annals of Human Biology| volume = 15| issue = 2| pages = 161–165| year = 1988| pmid = 3355105}} However, in 2013, the reverse observation was made.{{cite journal|last1=Myrskyla|first1=M|title=The association between height and birth order: evidence from 652,518 Swedish men.|journal=Journal of Epidemiology and Community Health|date=July 2013|volume=67|issue=7|pages=571–7|pmid=23645856|doi=10.1136/jech-2012-202296|s2cid=19510422|url=https://google.com}} The study authors suggest that the cause may be socioeconomic in nature.

=Genetics =

The precise relationship between genetics and environment is complex and uncertain. Differences in human height is 60−80% heritable, according to several twin studies{{cite journal|url=https://www.scientificamerican.com/article/how-much-of-human-height/|title=How much of human height is genetic and how much is due to nutrition? |author=Lai, Chao-Qiang |journal=Scientific American|date=11 December 2006}} and has been considered polygenic since the Mendelian–biometrician debate a hundred years ago. A genome-wide association (GWA) study of more than 180,000 individuals has identified hundreds of genetic variants in at least 180 loci associated with adult human height.{{cite journal|title=Hundreds of variants clustered in genomic loci and biological pathways affect human height|journal=Nature|year=2010|issue=7317|pages= 832–838 |vauthors=Lango Allen H, etal |volume=467|doi=10.1038/nature09410|pmid=20881960|pmc=2955183|bibcode=2010Natur.467..832L}} The number of individuals has since been expanded to 253,288 individuals and the number of genetic variants identified is 697 in 423 genetic loci.{{cite journal|title=Defining the role of common variation in the genomic and biological architecture of adult human height|journal=Nature Genetics|year=2014|issue=11|pages=1173–1186 |vauthors=Wood AR, etal |pmid=25282103|doi=10.1038/ng.3097|volume=46|pmc=4250049}} In a separate study of body proportion using sitting-height ratio, it reports that these 697 variants can be partitioned into three specific classes: (1) variants that primarily determine leg length, (2) variants that primarily determine spine and head length, or (3) variants that affect overall body size. This gives insights into the biological mechanisms underlying how these 697 genetic variants affect overall height.{{cite journal|title=Genome-wide Analysis of Body Proportion Classifies Height-Associated Variants by Mechanism of Action and Implicates Genes Important for Skeletal Development|journal=American Journal of Human Genetics|year=2015 |vauthors=Chan Y, etal |pmid=25865494|doi=10.1016/j.ajhg.2015.02.018|volume=96|issue=5|pages=695–708|pmc=4570286}} These loci do not only determine height, but other features or characteristics.

Height, like other phenotypic traits, is determined by a combination of genetics and environmental factor. A child's height based on parental heights is subject to regression toward the mean, therefore extremely tall or short parents will likely have correspondingly taller or shorter offspring, but their offspring will also likely be closer to average height than the parents themselves. Genetic potential and several hormones, minus illness, is a basic determinant for height. Other factors include the genetic response to external factors such as diet, exercise, environment, and life circumstances.{{citation needed|date=March 2024}}

=Environmental and epigenetic effects=

The effect of environment on height is illustrated by studies performed by anthropologist Barry Bogin and coworkers of Guatemala Mayan children living in the United States. In the early 1970s, when Bogin first visited Guatemala, he observed that Mayan Indian men averaged {{convert|157|cm|ftin|abbr=on}} in height and the women averaged {{convert|142|cm|ftin|abbr=on}}. Bogin took another series of measurements after the Guatemalan Civil War, during which up to a million Guatemalans fled to the United States. He discovered that Maya refugees, who ranged from six to twelve years old, were significantly taller than their Guatemalan counterparts.{{Cite journal | volume = 19 | issue = 2 | pages = 40–44 | last = Bogin | first = Barry | title = The tall and the short of it | journal = Discover | access-date = 26 April 2013 | year = 1998 | url = https://growtallernatural.com/tallshort }}{{Dead link|date=November 2023 |bot=InternetArchiveBot |fix-attempted=yes }} By 2000, the American Maya were {{convert|10.24|cm|in|1}} taller than the Guatemalan Maya of the same age, largely due to better nutrition and health care. Bogin also noted that American Maya children had relatively longer legs, averaging {{convert|7.02|cm|in|1}} longer than the Guatemalan Maya (a significantly lower sitting height ratio).{{Cite journal | last1 = Bogin | first1 = B. | last2 = Rios | first2 = L. | doi = 10.1016/S1095-6433(02)00294-5 | title = Rapid morphological change in living humans: Implications for modern human origins | journal = Comparative Biochemistry and Physiology A | volume = 136 | pages = 71–84 | year = 2003 | pmid = 14527631| issue=1}}{{cite web |author=Krawitz, Jan |url=https://www.pbs.org/pov/pov2005/bigenough/special_heightgap_04.html |title=P.O.V. - Big Enough |publisher=PBS |date=28 June 2006 |access-date=22 January 2011 |archive-date=30 April 2009 |archive-url=https://web.archive.org/web/20090430043527/http://www.pbs.org/pov/pov2005/bigenough/special_heightgap_04.html |url-status=dead }}

The Nilotic peoples of Sudan such as the Shilluk and Dinka have been described as some of the tallest in the world. Dinka Ruweng males investigated by Roberts in 1953−1954 were on average {{convert|181|cm|ftin|abbr=on}} tall, and Shilluk males averaged {{convert|182|cm|ftin|abbr=on}}.{{Cite journal | last1 = Roberts | first1 = D.

Attributed as a significant reason for the trend of increasing height in parts of Europe are the egalitarian populations where proper medical care and adequate nutrition had been relatively equally distributed as of 2004.{{Cite journal | last1 = Komlos | first1 = J. | last2 = Baur | first2 = M. | doi = 10.1016/j.ehb.2003.12.006 | title = From the tallest to (one of) the fattest: The enigmatic fate of the American population in the 20th century | journal = Economics & Human Biology | volume = 2 | pages = 57–74 | year = 2004 | pmid = 15463993| issue=1| citeseerx = 10.1.1.651.9270 | s2cid = 14291466 }} The uneven distribution of nutritional resources makes it more plausible for individuals with better access to resources to grow taller, while individuals with worse access to resources have a lessened chance of growing taller.{{Cite journal|last1=Baten|first1=Joerg|last2=Moradi|first2=Alexander|date=2005|title=Inequality in Sub-Saharan Africa: New Data and New Insights from Anthropometric Estimates|journal=World Development|volume=33|issue=8|pages=1233–1265|doi=10.1016/j.worlddev.2005.04.010}}

Changes in diet (nutrition) and a general rise in quality of health care and standard of living are the cited factors in Asian populations.

Average height in a nation is correlated with protein quality. Nations that consume more protein in the form of meat, dairy, eggs, and fish tend to be taller, while those that obtain more protein from cereals tend to be shorter.{{citation needed|date=June 2018}} Therefore, populations with high cattle per capita and high consumption of dairy live longer and are taller.

Role for an individual

Studies show that there is a correlation between small stature and a longer life expectancy. Individuals of small stature are also more likely to have lower blood pressure and are less likely to acquire cancer. The University of Hawaii has found that the "longevity gene" FOXO3 that reduces the effects of aging is more commonly found in individuals of a small body size. Short stature decreases the risk of venous insufficiency. Certain studies have shown that height is a factor in overall health while some suggest tallness is associated with better cardiovascular health and shortness with longevity.{{Cite journal|vauthors=Samaras TT, Elrick H |title=Height, body size, and longevity: is smaller better for the humanbody? |journal=The Western Journal of Medicine |volume=176 |issue=3 |pages=206–8 |year=2002 |pmid=12016250 |pmc=1071721 |doi=10.1136/ewjm.176.3.206}} Cancer risk has also been found to grow with height.{{cite news| url=https://www.cbc.ca/news/health/cancer-risk-may-grow-with-height-1.1109553 | work=CBC News | title=Cancer risk may grow with height | date=21 July 2011}} Moreover, scientists have also observed a protective effect of height on risk for Alzheimer's disease, although this fact could be a result of the genetic overlap between height and intracraneal volume and there are also genetic variants influencing height that could affect biological mechanisms involved in Alzheimer's disease etiology, such as insulin-like growth factor 1 (IGF-1).{{Cite journal|last1= Jansen|first1=I.E.|last2=Savage|first2=J.E.|last3=Watanabe|first3=K.|last4=Bryois|first4=J.|last5=Williams|first5=D.M.|last6=Steinberg|first6=S.|last7=Sealock|first7=J.|last8=Karlsson|first8=I.K.|last9=Hägg|first9=S.|year=2019|title= Genome-wide meta-analysis identifies new loci and functional pathways influencing Alzheimer's disease risk |journal=Nature Genetics|volume=51|issue=3|pages=404–413|doi=10.1038/s41588-018-0311-9|pmid= 30617256|pmc= 6836675|hdl= 10037/17318}}

Nonetheless, modern westernized interpretations of the relationship between height and health fail to account for the observed height variations worldwide.Cavalli-Sforza, L.L., & Cavalli-Sforza, F., 1995, The Great Human Diasporas, Cavalli-Sforza and Cavalli-Sforza note that variations in height worldwide can be partly attributed to evolutionary pressures resulting from differing environments. These evolutionary pressures result in height-related health implications. While tallness is an adaptive benefit in colder climates such as those found in Europe, shortness helps dissipate body heat in warmer climatic regions. Consequently, the relationships between health and height cannot be easily generalized since tallness and shortness can both provide health benefits in different environmental settings.

In the end, being excessively tall can cause various medical problems, including cardiovascular problems, because of the increased load on the heart to supply the body with blood, and problems resulting from the increased time it takes the brain to communicate with the extremities. For example, Robert Wadlow, the tallest human known to verifiable history, developed difficulty in walking as his height increased throughout his life. In many of the pictures of the latter portion of his life, Wadlow can be seen gripping something for support. Late in his life, although he died at age 22, he had to wear braces on his legs and walk with a cane; and he died after developing an infection in his legs because he was unable to feel the irritation and cutting caused by his leg braces.

Sources are in disagreement about the overall relationship between height and longevity. Samaras and Elrick, in the Western Journal of Medicine, demonstrate an inverse correlation between height and longevity in several mammals including humans.

Women whose height is under {{cvt|150|cm|ftin|abbr=on}} may have a small pelvis, resulting in such complications during childbirth as shoulder dystocia.{{cite web|last=Merck|title=Risk factors present before pregnancy|url=http://www.merck.com/mmhe/sec22/ch258/ch258b.html|work=Merck Manual Home Edition|publisher=Merck Sharp & Dohme}}

A study done in Sweden in 2005 has shown that there is a strong inverse correlation between height and suicide among Swedish men.{{Cite journal|vauthors=Magnusson PK, Gunnell D, Tynelius P, Davey Smith G, Rasmussen F |title=Strong inverse association between height and suicide in a large cohort of Swedish men: evidence of early life origins of suicidal behavior? |journal=The American Journal of Psychiatry |volume=162 |issue=7 |pages=1373–5 |year=2005 |pmid=15994722 |doi=10.1176/appi.ajp.162.7.1373}}

A large body of human and animal evidence indicates that shorter, smaller bodies age more slowly, and have fewer chronic diseases and greater longevity. For example, a study found eight areas of support for the "smaller lives longer" thesis. These areas of evidence include studies involving longevity, life expectancy, centenarians, male vs. female longevity differences, mortality advantages of shorter people, survival findings, smaller body size due to calorie restriction, and within-species body size differences. They all support the conclusion that smaller individuals live longer in healthy environments and with good nutrition. However, the difference in longevity is modest. Several human studies have found a loss of 0.5 years/centimeter of increased height (1.2 yr/inch). But these findings do not mean that all tall people die young. Many live to advanced ages and some become centenarians.Samaras TT 2014, Evidence from eight studies showing smaller body size is related to greater longevity JSRR 3(16):2150-2160. 2014: article no.

In most occupational fields, body height is not relevant to how well people are able to perform; nonetheless several studies found that success was positively correlated with body height, although there may be other factors such as sex or socioeconomic status that are correlated with height which may account for the difference in success.{{Cite journal |url=http://www-personal.umich.edu/~dansilv/height.pdf |title=The Effect of Adolescent Experience on Labor Market Outcomes: The Case of Height |first1=Persico |last1=Nicola |first2=Postlewaite |last2=Andrew |journal=Journal of Political Economy |volume=112 |pages=1019–1053 |year=2004 |doi=10.1086/422566 |last3=Silverman |first3=Dan |issue=5 |s2cid=158048477 }}{{Cite journal |url=http://www.diw-berlin.de/documents/dokumentenarchiv/17/diw_01.c.41848.de/paper2004_heineck.pdf |title=Up in the skies?

Certain ancient human populations were quite tall, even surpassing the average height of the tallest of modern countries. For instance, certain hunter-gatherer populations living in Europe during the Paleolithic Era and India during the Mesolithic Period averaged heights of around {{convert|183|cm|ftin|abbr=on}} for males, and {{convert|172|cm|ftin|abbr=on}} for females.{{cite journal | url=https://core.ac.uk/download/pdf/5105466.pdf | doi=10.1353/asi.2003.0042 | title=Skeletal Variation among Mesolithic People of the Ganga Plains: New Evidence of Habitual Activity and Adaptation to Climate | year=2003 | last1=Lukacs | first1=John R. | last2=Pal | first2=J.

Human height worldwide sharply declined with the advent of the Neolithic Revolution, likely due to significantly less protein consumption by agriculturalists as compared with hunter-gatherers.

During the Bronze Age, height varied significantly by region.

Adult height between populations often differs significantly. For example, the average height of women from the Czech Republic is greater than that of men from Malawi. This may be caused by genetic differences, childhood lifestyle differences (nutrition, sleep patterns, physical labor), or both.

Depending on sex, genetic, and environmental factors, shrinkage of stature may begin in middle age in some individuals but tends to be universal in the extremely aged. This decrease in height is due to such factors as decreased height of inter-vertebral discs because of desiccation, atrophy of soft tissues, and postural changes secondary to degenerative disease.

Working on data of Indonesia, the study by Baten, Stegl and van der Eng suggests a positive relationship of economic development and average height.

  • Some studies may allow subjects to self-report values.{{cite news |vauthors=Amos J |title=Dutch men revealed as world's tallest |url=https://www.bbc.com/news/science-environment-36888541 |publisher=BBC News |date=26 July 2016 |access-date=10 November 2018 |archive-date=9 May 2022 |archive-url=https://web.archive.org/web/20220509041414/https://www.bbc.com/news/science-environment-36888541 |url-status=live }} Generally speaking, self-reported height tends to be taller than measured height, although the overestimation of height depends on the reporting subject's height, age, gender and region.{{cite journal | vauthors = Krul AJ, Daanen HA, Choi H | title = Self-reported and measured weight, height and body mass index (BMI) in Italy, the Netherlands and North America | journal = European Journal of Public Health | volume = 21 | issue = 4 | pages = 414–419 | date = August 2011 | pmid = 20089678 | doi = 10.1093/eurpub/ckp228 | doi-access = free }}{{cite journal | vauthors = Lucca A, Moura EC | title = Validity and reliability of self-reported weight, height and body mass index from telephone interviews | journal = Cadernos de Saude Publica | volume = 26 | issue = 1 | pages = 110–122 | date = January 2010 | pmid = 20209215 | doi = 10.1590/s0102-311x2010000100012 | doi-access = free }}{{cite web|url=http://www.statcan.gc.ca/pub/11-522-x/2008000/article/11002-eng.pdf|title=Methodological issues in anthropometry: self-reported versus measured height and weight|vauthors=Shields M, Gorber SC, Tremblay MS|date=2009|publisher=Proceedings of Statistics Canada's Symposium 2008.

  • Test subjects may have been invited instead of random sampling, resulting in sampling bias.
  • Some countries may have significant height gaps between different regions. For instance, one survey shows there is {{convert|10.8|cm|in|1}} gap between the tallest state and the shortest state in Germany.{{cite web| publisher= WWC Web World Center GmbH G.R.P. Institut für Rationelle Psychologie |url=http://www.menshealth.de/sixcms/media.php/37/Mens_Health_Fettatlas_2008.pdf |title=Körpermasse Bundesländer & Städte |archive-url=https://web.archive.org/web/20120816023627/http://www.menshealth.de/sixcms/media.php/37/Mens_Health_Fettatlas_2008.pdf |archive-date=16 August 2012 |date=31 October 2007}} Under such circumstances, the mean height may not represent the total population unless sample subjects are appropriately taken from all regions with using weighted average of the different regional groups.
  • Different social groups can show different mean height. According to a study in France, executives and professionals are {{convert|2.6|cm|in|1}} taller, and university students are {{convert|2.55|cm|in|1}} taller than the national average.{{cite journal|author=Herpin, Nicolas|year=2003|title=La taille des hommes: son incidence sur la vie en couple et la carrière professionnelle|url=http://www.insee.fr/fr/ffc/docs_ffc/es361d.pdf|journal=Économie et Statistique|volume=361|issue=1|pages=71–90|doi=10.3406/estat.2003.7355|access-date=11 February 2012|archive-date=19 September 2018|archive-url=https://web.archive.org/web/20180919082242/http://www.insee.fr/fr/ffc/docs_ffc/es361d.pdf|url-status=live}} As this case shows, data taken from a particular social group may not represent a total population in some countries.
  • Height measurement can vary over the course of a day, due to factors such as a decrease from exercise done directly before measurement (i.e., inversely correlated), or an increase since lying down for a significant period of time (i.e., positively correlated). For example, one study revealed a mean decrease of {{convert|1.54|cm|in|1}} in the heights of 100 children from getting out of bed in the morning to between 4 and 5 p.m. that same day.{{cite journal | vauthors = Buckler JM | title = Variations in height throughout the day | journal = Archives of Disease in Childhood | volume = 53 | issue = 9 | pages = 762 | date = September 1978 | pmid = 568918 | pmc = 1545095 | doi = 10.1136/adc.53.9.762 | doi-access = free }} Such factors may not have been controlled in all of the following studies.

In 2017, men from Bosnia and Herzegovina, the Netherlands, Montenegro, and Serbia have the tallest average height.{{Cite journal|last1=Grasgruber|first1=Pavel|last2=Popović|first2=Stevo|last3=Bokuvka|first3=Dominik|last4=Davidović|first4=Ivan|last5=Hřebíčková|first5=Sylva|last6=Ingrová |first6=Pavlína |last7=Potpara|first7=Predrag|last8=Prce|first8=Stipan|last9=Stračárová|first9=Nikola|date=2017-04-01|title=The mountains of giants: an anthropometric survey of male youths in Bosnia and Herzegovina|journal=Royal Society Open Science |volume=4|issue=4|pages=161054|doi=10.1098/rsos.161054|pmid=28484621|pmc=5414258|bibcode=2017RSOS....461054G|issn=2054-5703}}{{Cite news|url=https://www.seeker.com/health/the-tallest-men-in-the-world-trace-back-to-prehistoric-mammoth-hunters|title=The Tallest Men in the World Trace Back to Paleolithic Mammoth Hunters|last=Viegas|first=Jen|date=2017-04-11|work=seeker|access-date=2017-04-12}}

In 2024, the world's three tallest populations were in the Netherlands, Montenegro, and Estonia.{{cite web | title=Average Height by Country 2024 | website=World Population by Country 2024 (Live) | url=https://worldpopulationreview.com/country-rankings/average-height-by-country | access-date=2025-03-06}}{{cite web | last=Bostock | first=Bill | last2=McGrath | first2=Jenny | title=The countries with the tallest people in the world, ranked | website=Business Insider | date=2024-12-18 | url=https://www.businessinsider.com/tallest-people-world-countries-ranked-2019-6#2-montenegros-mean-height-is-5-feet-955-inches-17665-cm-24 | access-date=2025-03-06}}

A 2005 study found teenagers from the Dinaric Alps to be the tallest people in the world.{{cite journal|title=Les Alpes Dinariques : un peuple de sujets de grande taille Average height of adolescents in the Dinaric Alps |date=1 September 2005|pmid=16168365 | doi=10.1016/j.crvi.2005.07.004|volume=328|issue=9|journal=Comptes Rendus Biologies|pages=841–6 | last1 = Pineau | first1 = JC | last2 = Delamarche | first2 = P | last3 = Bozinovic | first3 = S|url=https://comptes-rendus.academie-sciences.fr/biologies/articles/10.1016/j.crvi.2005.07.004/ | quote=This study contributes to an update of average heights among European populations. Our investigation covering 2705 boys and 2842 girls aged 17 years, shows that, contrary to the general belief, adolescents of the Dinaric Alps are, on average, the tallest in Europe. With an average height of 185.6 cm, they are taller than Dutch adolescents (184 cm on average).}}

Dinka people are sometimes noted for their height, with the Tutsi of Rwanda believed to be the tallest people in Africa.{{cite web |url=http://www.nmafa.si.edu/exhibits/focus/tutsi.html |title=The Tutsi |work=In and Out of Focus: Images from Central Africa 1885–1960 |publisher=National Museum of African Art, Smithsonian Institution}} In a sample of 52 Dinka Agaar, Roberts and Bainbridge reported a mean height of {{cvt|182|cm|ftin|abbr=on}}. In 227 Dinka Ruweng, they reported {{cvt|181|cm|ftin|abbr=on}}. Both figures derived from 1953 to 1954.{{cite journal |last1=Roberts |first1=D. F. |last2=Bainbridge |first2=D.

Measurement

Height measurements are by nature subject to statistical sampling errors even for a single individual. In a clinical situation, height measurements are seldom taken more often than once per office visit, which may mean sampling taking place a week to several months apart. The smooth 50th percentile male and female growth curves illustrated above are aggregate values from thousands of individuals sampled at ages from birth to age 20. In reality, a single individual's growth curve shows large upward and downward spikes, partly due to actual differences in growth velocity, and partly due to small measurement errors.

For example, a typical measurement error of plus or minus {{cvt|0.5|cm|1}} may completely nullify 0.5 cm of actual growth resulting in either a "negative" 0.5 cm growth (due to overestimation in the previous visit combined with underestimation in the latter), up to a {{cvt|1.5|cm|1}} growth (the first visit underestimating and the second visit overestimating) in the same elapsed period between measurements. Note there is a discontinuity in the growth curves at age 2, which reflects the difference in recumbent length (with the child on his or her back), used in measuring infants and toddlers, and standing height typically measured from age 2 onwards.

Crown-rump length is the measurement of the length of human embryos and fetuses from the top of the head (crown) to the bottom of the buttocks (rump). It is typically determined from ultrasound imagery and can be used to estimate gestational age.

Until two years old, recumbent length is used to measure infants.{{Cite web|url=https://www.ihs.gov/hwm/infantguidelines/|title = Infant Guidelines}} Length measures the same dimension as height, but height is measured standing up while the length is measured lying down. In developed nations, the average total body length of a newborn is about {{convert|50|cm|abbr=on}}, although premature newborns may be much smaller.

Standing height is used to measure children over two years old{{Cite web|url=https://www.ihs.gov/hwm/childguidelines|title=Child Guidelines}} and adults who can stand without assistance. Measure is done with a stadiometer. In general, standing height is about {{cvt|0.7|cm|1}} less than recumbent length.[https://www.who.int/childgrowth/training/module_b_measuring_growth.pdf?ua=1 Measuring a child's growth] p.19, World Health Organization

Surrogate height measurements are used when standing height and recumbent length are impractical. For example, the Chumlea equation, which uses knee height, can be used to estimate the height of hospitalized patients when standard methods are impractical.{{Cite journal|doi = 10.1016/j.eclnm.2008.01.004|title = Stature estimation using the knee height determination in critically ill patients|year = 2008|last1 = Berger|first1 = Mette M.|last2 = Cayeux|first2 = Marie-Christine|last3 = Schaller|first3 = Marie-Denise|last4 = Soguel|first4 = Ludivine|last5 = Piazza|first5 = Guido|last6 = Chioléro|first6 = René L.|journal = e-SPEN, the European e-Journal of Clinical Nutrition and Metabolism|volume = 3|issue = 2|pages = e84–e88}} Some other techniques include arm span, sitting height, and ulna length.
