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.

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 layers of 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!

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.

Types of Custom Mats and Linen Liners

We offer a range of custom picture mats such as decorative mats, acid-free mats, suede mats, metallic mats and oversize mats to get the look you want. Our color selection includes black and white, neutrals and rich colors perfect for layering mats and color matching with each piece of art.

How to Choose the Right Liner or Mat for Your Frame

Achieve the custom matted picture frames you want with the best mat for every project. Customize your mats by completing the following steps to get the best results:


1.Decide on the number of mats Start by deciding on the quantity of mats you want to use. Is a classic single mat sufficient, or do you want to make a bolder statement with double or triple layers?
2.Choose a mat type and material Select the type of picture mats that work best for your piece. The material and texture of your mat matters, so choose from decorative and acid-free options as well as suede and metallic mats for your prints and photos, or pick linen liners for canvas art.
3.Pick a mat color Once you know how many and the type of mats you need, explore our range of mat color options to find the most complementary custom picture mats for your artwork.
4.Select the mat size Measure the portion of the artwork or photo that you want visible through the window of the mat to get the inner dimensions. If you already have a picture frame in mind, the frame size will help you determine the outer dimensions of your mat. If you don’t have one yet, we’ve got many picture frames to choose from to accompany our custom mats for frames. You can pick a frame that accommodates your photo or artwork as well as the mat width you want.
Note: Remember to factor in whether you want your framing mat board to have an equal width on all four sides or a bottom-weighted option. Bottom-weighted mats are wider at the bottom than the other sides and can really make your art pop.
