Mats cut to fit your display
We cut picture mats in any size you need, any width, any height. Our designer gives you full control over mat width, opening size, shape, and color. Used by photographers, artists, galleries, and anyone framing artwork that doesn't fit standard sizes.
Single or Double Mat, Your Choice
Single mats work great for clean, minimal presentations. Double mats add a second layer with a thin reveal border (typically 1/8 to 1/4 inch) showing between the opening and outer mat. This creates depth and lets you add a contrasting color accent. Double mats are standard in professional framing because they look more sophisticated and create extra spacing between your art and the glass. You can also add V-groove decorative detail for visual interest.
50 Mat Colors, Neutrals to Bold
Choose from 46 professional mat colors. Neutrals include whites, off-whites, creams, blacks, and grays that work with any artwork. Premium colors add earth tones, jewel tones, and specialty hues for projects that need more personality. All mats use the same quality materials professional framers rely on.
Opening Shapes, Rectangle & Oval
Choose from rectangle or oval openings for your mat. Each shape cuts to 1/8-inch precision with a clean beveled edge. Rectangles work for nearly everything. Ovals are popular for portraits and add a classic, polished look. Additional options include rounded corners, v-grooves for a gallery finish, and protective backing boards.
Decorative V-groove detail
V-groove is a decorative mat cutting technique that creates an elegant, precise groove in the mat surface outside your opening. The groove appears as a subtle channel that adds visual interest and a professional gallery look. V-groove creates dimension and draws the eye to your artwork without requiring a double mat, though it works beautifully with double mats too.
