Standard Black Backer Boards are identical in type to the Pitch Black, (black core) mat boards, but without any openings. They are ideal for everyday, acid-free backing of posters, decorative art prints, craft projects and photographs. These backing boards can also be used as blank mats for those wanting to cut their own openings.

  • Smooth backing board that's deep black on one side (dark gray on the reverse side)
  • Buffered, pH neutral, non-conservation, acid-free mounting board
  • Standard 4-ply backing board, .045" thickness

!! MAX Custom Opening Size is 2 inches smaller than Mat Size. This will allow for a 1 inch mat border on all sides.

Custom Opening Sizes

We will cut Custom Openings 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.

Custom Outsize Dimenison Mats

Need a custom mat board size not listed? No problem, simply select the closest size item listed on the site that your custom size will fit into, and we'll cut it down to size for you. No extra cost. Example, if you want a custom size mat of 11x15, you would select a 12x16 mat size; if you want a 17x22 mat you would select a 18x24 mat size. Simply select the larger mat size and then, in the Special Instructions box, type in the outside dimensions that you want. Example, 'Cut mat to 17x22' or 'OD 17x22'. We will then cut the mat (and any matching Backers, if chosen) 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.
