A clothes line, also spelled clothesline, also known as a wash line, is a device for hanging clothes on for the purpose of drying or airing out the articles. It is made of any type of rope, cord, wire, or twine that has been stretched between two points (e.g. two posts), outdoors or indoors, above ground level. Washing lines are attached either from a post or a wall, and are frequently located in back gardens, or on balconies. Longer washing lines often have props holding up the mid-section so the weight of the clothing does not pull the clothesline down to the ground.
Clothing that has recently been washed is hung over the line to dry. Nowadays it is held in place with clothespins, but until the 19th century laundry was simply draped over the line (and often blew away), as is visible in artistic depictions of clotheslines from earlier periods. The clothespin was not invented until 1809.{{cite news |title=The curious history of the clothespeg |url=https://medium.economist.com/the-curious-history-of-the-clothespeg-3f8615519c61 |access-date=8 May 2025 |work=Medium |publisher=The Economist |date=22 December 2016 |language=en}}
More elaborate rotary washing lines save space and are typically retractable and square or triangular in shape, with multiple lines being used (such as the Hills Hoist from Australia). Some can be folded up when not in use. The notable con man Steve Comisar once sold a solar powered clothes dryer advertised in national magazines as a scientifically proven, space age method of drying clothes using only the power of the sun. Customers received a length of clothesline. In Scotland, many tenement buildings have a "drying green", which is a communal area predominantly used for clothes lines. A "drying green" may also be used as a recreational space for tenants. The overhead clothes airer is an indoor version hung at ceiling level and also raised and lowered with pulleys.
Comparison with clothes dryer

Both clothes lines and clothes dryers serve the same purpose: drying clothes that have been recently washed, or that are wet in general. A laundry line saves money and a clothes dryer emits (2 kg CO2eq of greenhouse gas on average per load).{{Citation |title=Environmental impact of a clothes dryer and a clothes line |date=January 10, 2008 |url=http://ecofx.org/wiki/index.php?title=clothes_dryer |access-date=January 11, 2009 |archive-url=https://web.archive.org/web/20150206030605/http://ecofx.org/wiki/index.php?title=Clothes_dryer |archive-date=February 6, 2015 |url-status=dead |publisher=ecofx}} Dryers also cause more fabric wear than clotheslines.{{Citation | last=Aun | first=Leslie M. | title=Nature's Dryer Revisited | newspaper=The Washington Post | date=August 17, 2006 | url=https://www.washingtonpost.com/wp-dyn/content/article/2006/08/16/AR2006081600394.html}} Neighbors may find clotheslines aesthetically unpleasant.
Drying laundry indoors
Laundry may be dried indoors rather than outdoors for a variety of reasons including:
- inclement weather
- physical disability
- lack of space for a line
- reduce the damage to fabrics from sun's UV rays
- legal restrictions{{ cite web | url=http://www.abajournal.com/news/article/20_right_to_dry_states_outlaw_clothesline_bans_is_yours_among_them | last=Neil | first=Martha | publisher=ABA Journal | date=August 14, 2013 | title=19 'right to dry' states outlaw clothesline bans; is yours among them? }}
- to raise the humidity level indoors, and lower the air temperature indoors
- convenience
- to preserve privacy and as a safeguard against vandalism
Several types of devices are available for indoor drying. A clotheshorse can help save space in an apartment, or clothes lines can be strung in the basement during the winter. Small loads can simply be draped over furniture or a shower curtain pole. The drying time indoors will typically be longer than outdoor drying because of the lack of direct solar radiation and of the convective assistance of the wind.
The evaporation of the moisture from the clothes will cool the indoor air and increase the humidity level, which may or may not be desirable. In cold, dry weather, moderate increases in humidity make most people feel more comfortable. In warm weather, increased humidity makes most people feel even hotter. Increased humidity can also increase growth of fungi, which can cause health problems.
An average-sized wash load will convert approximately {{nowrap|4965 kilojoules}} of ambient heat into latent heat that is stored in the evaporated water, as follows. A typical 4 kg load of laundry can contain 2.2 kg of water, after being spun in a laundry machine.{{ cite web | url=http://www.explainthatstuff.com/how-clothes-tumble-dryers-work.html | title=How clothes dryers work {{!}} The science of drying clothes | first=Chris | last=Woodford |author1-link=Chris Woodford (author)| date=July 13, 2018 | publisher=ExplainThatStuff.com}} To determine how much heat has been converted in drying a load of laundry, weigh the clothes when they are wet and then again after the clothes have dried. The difference is the weight of the water that was evaporated from them. Multiply that weight in kg by 2,257 kJ/kg,{{Cite web|url=http://www.engineeringtoolbox.com/fluids-evaporation-latent-heat-d_147.html|title=Fluids - Latent Heat of Evaporation}} which is the heat of vaporization per kilogram, to obtain the number of kilojoules that went into evaporating the water, or multiply by 0.6250 kWh/kg to get kilowatt-hours. If the moisture later condenses inside the house, the latent heat will return to ambient heat which could increase the temperature of the air in the room slightly.Diamond, Sheldon R. (1970). Fundamental Concepts of Modern Physics. USA: AMSCO School Publications, Inc. pp. 205. "During evaporation... The surroundings thereby become the ultimate source of the energy required to change the phase of [water] from liquid to gas." To obtain a good approximation of the effect this would have in a particular situation, the process can be traced on a psychrometric chart.
Factors that determine the drying duration
Various factors determine the duration of drying and can help to decide whether to use a drier or a clothes line
- Placement of clothes line
- The environmental temperature - increase of temperature decreases the drying duration
- The environmental humidity - decrease of humidity will decrease the drying duration
- Wind velocity - Sometimes people put a fan near the clothes when drying them indoors
- Direct sun - usually only the external line will be exposed to direct sun, so usually people put the thickest clothes on the most external line.
- Cloth thickness
Drying laundry in freezing conditions
Laundry may be dried outdoors when the temperature is well below the freezing point. First, the moisture in the laundry items will freeze and the clothing will become stiff. Then the frost on the clothes will sublimate into the air, leaving the items dry. It takes a long time and it is usually much quicker to dry them indoors, but indoor drying transfers heat from the air to water vapor, so it is a trade-off between speed and energy efficiency. The added humidity cancels out the reduction in air temperature to some extent.
North American controversy
Controversy surrounding the use of clothes lines has prompted many governments to pass "right-to-dry" laws allowing their use.{{Citation | last=Rosenthal | first=Elisabeth | title=A Line in the Yard: The Battle Over the Right to Dry Outside | newspaper=The New York Times | date=April 17, 2008 | url=https://www.nytimes.com/2008/04/17/world/americas/17clothesline.html }} According to Ian Urbina, a reporter for The New York Times, "the majority of the 60 million people who now live in the [United States'] roughly 300,000 private communities" are forbidden from using outdoor clothes lines.{{Cite web | work=The New York Times | date=October 10, 2009 | first=Ian | last=Urbina | url=https://www.nytimes.com/2009/10/11/us/11clothesline.html | title=Debate Follows Bills to Remove Bans on Clotheslines }}
