How to Determine Frame Size

Important:  The words "frame size" refer to the dimensions of the recess (or "rabbet") at the back of the frame into which the matboard, backing and glass are loaded.  For this reason, once you've determined the overall size of your matboard, backing and glass for a given project, you've determined your frame size. 

For help in determining the overall size of your mat board, backing and glass see the box below. ↓ 

Note: All frames are designed and built 1/8" larger on each dimension than the size called for.  This so called "allowance" is common in picture framing and is provided to make sure the mat and backing still fit into the frame even if they are cut a little too large.  You do not have to factor anything into your calculations for the allowance, just order the frame in accordance with the overall mat size and the allowance will automatically be added.  If you do not want an allowance, you should call us at 1-800-246-4726 and specify "no allowance".
