The Paris point is a unit of length defined as ⅔ of a centimetre (6.6 mm or ~0.26 in). It is commonly used for shoe sizes in Continental Europe.

Its origin probably lies in 2/3 of a centimetre being very close to a quarter of an inch; a French inch pouce-roi is around 27 mm, a quarter of that is 6.7 mm, close to 6.6 mm defined for the Paris point.[1]
