Perfect for DIY framers, artists, and craft enthusiasts - our Ultimate White Blank Mat Board Sheets offer a flexible, professional-grade option for custom-cut projects and backing applications.
These uncut, full-size sheets are made from 4-ply (1.4mm thick) Ultimate White matboard with a bright white core. Each sheet is acid-free and buffered with calcium carbonate to preserve the quality of your prints, artworks, or presentations over time.
Blank matboards are commonly used to create custom window mats, backing layers for framing, or as a base for portfolios, school projects, and gallery displays.
If you're looking to cut your own mat openings or use a full sheet as a protective layer, these boards provide the versatility you need.

Use our helpful Matboard Border Calculator to calculates the distance of mat board borders inside your picture frame, based on your artwork dimensions and frame dimensions. You can also generate a scaled diagram for this, with dimensions as well.
Artwork Dimensions
Enter dimensions of your artwork in centimeters, or inches. The calculator will subtract 0.5cm from each side for an overlap of the matboard and the edges of your artwork.
Frame Dimensions
Do not enter the overall outside dimensions of your frame. Instead, measure the backing from behind your frame, inside the frame rebate. These measurements will accurately match your glass size.

Packaging
- Sizes up to A2 come in a resealable 40-micron cello bag
- Larger sizes are professionally shrink-wrapped

Fitting & Size Notes
- Window Opening: Cut slightly smaller than the image size (approx. 3–5 mm overlap) to ensure your photo or artwork sits neatly behind the mat board
- External Size: Cut to exact inch dimensions to match standard frame sizes
- Manufacture Markings: The reverse side of some window mats may contain printed manufacturer markings, which are normal and unavoidable
Colour Disclaimer
Colours may appear slightly different on screen compared to the actual mat board, due to variations in display and device settings.
