Frames By Mail matting instructions

Please note that you are free to adjust the width of each of the matting margins. The size entered is your image size. The final frame size is your image size plus the matting, so wider mat margins or additional mat layers will make the finished frame larger. The first mat (top mat) will have a 2-inch default margin, and second or third mats are 1/4 inch by default. Press “Continue” below to close this message and select your mat.

First matting layer options

All types

Customize the sizing of your matting. On the first mat, the width on each side must be at least 1 3/8"
