Standard Sizes Chart

At Documounts we can cut any size mat you need at no extra charge. If you know the outside and opening dimension that you want you can begin at the Matboard Builder.

However, if you need a chart to see what the usual standard size outside and opening size cuts are we have provided one for you below.

If you are looking for basic standard size mats you may want to check out our line of Pre-Cut and Market Ready Kits here.
