13x13 Beige / French Creme Custom Mat for Picture Frame with 9x9 opening size (Mat Only, Frame NOT Included)

The mat is designed to accommodate a 9x9 inch photograph. However, the precise cutting of the opening measures 8.75 by 8.75 inches. This slight reduction ensures that the edges of your photograph are securely held within the mat's border when installed, preventing slippage and maintaining a clean presentation.

Yes, this mat is constructed from lignin-free and pH-neutral materials. This is crucial for archival purposes, as it prevents the mat from yellowing or becoming acidic over time, which can damage the artwork it protects. The standard 4-ply thickness also provides a substantial, protective barrier.

ArtToFrames explicitly states that custom opening sizes are available upon request. If your artwork or photograph does not perfectly match the standard 9x9 inch opening, we recommend contacting the manufacturer directly to inquire about bespoke cutting options that might better suit your specific framing project.

'4 ply' refers to the thickness of the mat board, which is approximately 1/16th of an inch or 1.5mm. This standard thickness is commonly used in professional custom framing shops, offering a robust and visually appealing presence that complements the artwork without being overly bulky. It provides good rigidity and support.

The mat board itself is cut to 13x13 inches, matching the external dimensions of the frame it is designed for. When placing the mat within the frame, ensure that the frame's rabbet (the inner lip that holds the glass and artwork) is compatible with a 13x13 inch mat. The opening within the mat will then reveal your 9x9 inch photo.
