Its long length is designed to 'ride over' the undulations of an uneven surface, skimming off the peaks, gradually creating a flatter surface. In thicknessing or preparing rough stock, the jointer plane is usually preceded by the fore plane or jack plane and followed by the smoothing plane.Schwarz, Christopher.

Jointer planes are typically {{convert|20|to|24|in|mm}} long, and are the longest hand planes commonly used. Under the Stanley Bailey numbering system, #7 and #8 planes are jointer planes.{{Cite web|title=Stanely Bailey Planes Miscellaneous Data|url=http://primeshop.com/access/woodwork/stanleyplane/DataMisc.htm|access-date=2020-10-09|website=primeshop.com|archive-date=2020-11-12|archive-url=https://web.archive.org/web/20201112012200/http://primeshop.com/access/woodwork/stanleyplane/DataMisc.htm|url-status=dead}}

The use of the name jointer plane dates back to at least the 17th century, referring to the process of readying the edges of boards for jointing.{{Cite book|last=Moxon|first=Joseph|url=http://hdl.handle.net/2027/mdp.39015028306002|title=Mechanick Exercises: or, The Doctrine of Handy-Works Applied to the Arts of Smithing, Joinery, Carpentry, Turning, Bricklayery|year=1703|edition=3rd|location=London|pages=82|publisher=Printed for D.

As with other hand planes, jointer planes were originally made with wooden bodies. But, since the development of the metal-bodied hand plane at the end of the 19th century, wooden-bodied jointers have been largely superseded. Metal-bodied planes are heavier, which is particularly noticeable for planes as large as jointers. This can make metal-bodied jointers more tiring to use for extended periods of time.{{Cite book|last=Schwarz|first=Christopher|url=https://www.worldcat.org/oclc/875304703|title=The Anarchist's Tool Chest|publisher=Lost Art Press LLC|year=2011|isbn=978-0-578-08413-8|location=Fort Mitchell, KY|pages=65|oclc=875304703}}
