Choose Your Image Size
Select your desired image window size from the menu. This size should match the dimensions of your image or artwork.

Important: The mat’s window opening will be ½ inch smaller than the size you select. This ensures proper overlap to hold your image in place.
Example: If you select an 8x10" image size, the actual opening will be 7.5x9.5".

Double Mat 
When selecting a double mat, the top mat will reveal ¼ inch of the bottom mat around the window opening, adding depth and a layered look.
