What is a Picture Frame Mat?

Protective picture frame mats are specifically designed to create space between the art or photo and the acrylic or glass front so air can circulate. This helps prevent condensation from building up inside the frame over time for better preservation. It also provides a gallery-like aesthetic when framing documents , photos or other artwork.

Guide for Choosing Mat Width

Choosing Your Mat Width

Wider mats emphasize the art while creating a highly professional, gallery-quality presentation. We recommend a mat at least twice as wide as the width of the frame.

Abstract Art with Bottom Weighted Mat and Black Frame

Bottom-Weighted Mats

Bottom-weighting means making the bottom mat width slightly wider than the top, left and right sides to compensate for an optical illusion that happens where your bottom mat width looks narrower.

Color MATching

It’s best to choose a mat that complements the artwork, not everything around it. Choose a mat no lighter than the lightest color within your art, no darker than the darkest & no brighter than the brightest to add to your art.

Double Mats

Consider using white or a neutral color on top. Then, for the "reveal," (the inner mat closest to your artwork) punch up the color by matching the mat to a dominant color in the artwork. This color contrast is a nice way to make your art pop.

Triple Mats

Triple mats have 3 mats. Try two neutral outer mats with a pop of color on a third mat around your picture. It adds loads of dimension and draws the eye inwards to your art and photos!

Mat Samples

We offer FREE mat samples, so you can check out the color and texture of the mat, see how it looks with your art and frame.

What Are Linen Liners?

For canvas art, you will need a custom linen liner instead of a custom mat for a frame. These liners can be paired with ¾ framed stretch canvases and linen liner-compatible frames so your canvas wall art looks just as refined as your framed photos and prints.

How to Choose the Right Liner or Mat for Your Frame

Start by choosing the desired width for your custom photo mats or linen picture frame liners and decide whether you would like a bottom-weighted option.
