Here are the most common frame sizes and pre-cut mat openings available at your nearest craft-supply store.
We recommend an overlap of 1/8″ on all sides (1/4″ extra on the height and width) to ensure there is no gap between your image and the mat.
Whenever possible, measure your desired mat to ensure accuracy.
