Hello, in my experience woodworkers in the USA seldom use fractions or metric dimensions when describing their wood plans. Whereas here in the UK we talk of a piece of wood or timber (never lumber which means something else) as being four by two (4 by 2 inches) in the USA they always give the smaller number first. The way those dimensions were written for example 4/4 means 4x4 (four inches by four inches or 3x6 (three inches by six inches). Fractions when sometimes used are generally sixty fourths, thirty seconds or sixteenths of an inch and are written differently to the larger dimensions describing timber, I hope this is of use.
