This 23x31 frame is built for posters, gallery prints, and large-format photography. It includes 2 acid-free mats, a 20x28 mat and a 19x27 mat, giving you 4 ways to display artwork in a single frame.

Key Features

• Tempered glass front for scratch resistance and true clarity
• Solid wood border in a flat black finish, 1.5 in. wide and 1 in. thick
• 2 included mats: 1 with a 20x28 window and 1 with a 19x27 window
• Mats are acid-free, lignin-free, bevel-cut, 4-ply alpha cellulose for archival-safe display

4 Ways to Display

1. No mat: displays a full 22.5x30.5 in. image, ideal for 23x31 posters
2. Double matted: layer both mats for a framed 19x27 image with a classic double-mat reveal
3. 19x27 mat only: displays a 19x27 image with a wide single mat border
4. 20x28 mat only: displays a 20x28 poster with a clean single mat border

Mats overlap the artwork by 0.25 in. on each edge, so the viewable area is 19.5x27.5 in. with the 20x28 mat and 18.5x26.5 in. with the 19x27 mat.
