24x35 Antique Blue Dutch Blue Custom Mat for 20x31 Opening - Clean Fit

In this review the 24x35 Antique Blue / Dutch Blue custom mat is evaluated for hobby framers and photo preservers who need an accurately cut, archival-quality mat at a reasonable price. The bottom line: it is a straightforward mat-only option that delivers stable, acid-free support and true-to-color appearance for larger photos, with one clear selling point - precise measurement and cut quality that fits a 20x31 print when used in a 24x35 frame. The reviewer found it especially useful when a reliable, museum-safe mount is required without buying a full frame.

Key Features

• Material quality: Made from standard 4 ply matboard used in custom frame shops, the mat offers a familiar, professional feel that handles mounting and display work well.
• Archival construction: Lignin-free and pH-neutral materials protect photographs from yellowing and degradation over time.
• Designed fit: Sized to fit inside a 24x35 frame while accommodating a 20x31 photo, so users can pair it with common large-format framing.
• Precise opening: The actual opening is 19.75x30.75 in, which gives a snug, consistent reveal for the image and hides raw edges cleanly.
• Custom sizing option: Orders sold by the brand allow customers to request alternate opening sizes by email or contact link, giving flexibility for nonstandard prints.
• Color consistency: The Antique Blue / Dutch Blue tone holds true in natural light and complements both color and monochrome photographs without dominating the image.

Who It's For

The mat is well suited to DIY framers, photographers, galleries, and hobbyists who need a dependable archival matboard for a larger print and want an accurate pre-cut opening. It is particularly useful for those who plan to frame a 20x31 print in a standard 24x35 frame and value a neat, professional presentation.

People who should look elsewhere include buyers who need a full framed solution instead of mat-only, or those requiring elaborate custom bevels or decorative fillets not offered here; also, shoppers who want immediate non-customized same-day changes should note the explicit 2-hour window to request opening adjustments after ordering.
