Window sizes and type

What does it mean when a window is 4056FX or 2856SC?

Consider it to be a nominal size. It might be the glass size or it could be the glass including the sash. there is no such thing as a standard size window.

4056 often means 40 wide 56 tall. 2856 would be 28 wide 56 tall. No idea what the letters are, some of that is brand specific or changes depending on wIndow style.
