Custom Mats

 Custom Outsize Dimension Mats (up to 32x40 max.)

To order a custom size Mat Board, Backer or Acrylic, simply select the closest size listed on the site that your custom size would fit into. Then, in the Special Instructions box, right above the 'add to cart' button, type in the Outside Dimension you want. "Cut Outside Dimension to 17x22" or "OD 17x22".

We will then cut the custom item down to that size for you. No extra cost. Example, if you want a custom picture mat sized 11x15, you would select the 12x16 mat size; if you want a 17x22 mat you would select the 18x24 mat size.

Make sure your Opening Size is not too large for the new custom mat board size.


Custom Opening Sizes

Choose the Custom Opening Size option available on all mat products. Type in the custom size opening you want We will cut the opening EXACTLY as you type it in. If you type 8x10, the opening will be exactly 8x10.

Please note that if your paper size or artwork is 8x10 it may fall through the opening. In this case, you would want to specify an opening of say, 7.5x9.5, to allow for a .25" overlap on all four sides of the artwork/photo. Subtract .5" from the actual photo or paper size to get this number.
