Picture Frame Sizes
Standard photo and poster frame sizes in inches, centimetres and millimetres — so you can match a print to the right frame.
Most common photo sizes are 4×6, 5×7 and 8×10 in; popular poster frames are 16×20 and 24×36 in. The frame size is the outer glass size — to use a mat, pick a frame larger than your print.
