Custom Mats

Custom Mat Size (outside dimension, up to 32"x40" max.)

To order a custom size Mat Board, Backer or Acrylic, simply select the closest size item listed on the site that your custom size would fit into.

Example, if you want a custom picture mat sized 11x15, you would select the 12x16 mat size.

e.g. 18x22 mat, select the 18x24 mat size or 7x7 mat, select the 8x8 mat

Then, in the Special Instructions box, right above the 'add to cart' button, type in the Outside Dimension you want. "Cut Outside Dimension to 18x22" or "OD 18x22". We will then cut the custom item down to that size for you. No extra cost. 

!! Make sure your Opening Size is not too large for the new custom mat board size.
!! We can cut in increments of 1/8". 

Custom Opening Sizes

Choose the Custom Opening option available on all mat products under the Opening Size tab. 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.
