What ratio is 4×6?

4×6 is a 2:3 ratio. It shares that shape with 8×12, 12×18, 16×24, 24×36, so one 2:3 file prints them all. That matters because a print only fits a frame when the shapes match.

Will a 4×6 file fit the frame?

Only if the frame is the same 2:3 shape. Put a 4×6 file into a frame of a different ratio and you get borders or a cropped image. To cover every frame your buyers own, offer one file per ratio (2:3, 3:4, 4:5, 5:7, 11:14, ISO A).
