Cylinders with constant-width cross-section can be used as rollers to support a level surface. Another application of curves of constant width is for [[coinage shapes]], where regular [[Reuleaux polygon]]s are a common choice. The possibility that curves other than circles can have constant width makes it more complicated to check the [[Roundness (object)|roundness of an object]].

TheseCurves curvesof constant width have been generalized in several ways to higher dimensions and to [[non-Euclidean geometry]].
