This 28x28 square frame is built for posters, gallery prints, and large-format photography. It includes 2 acid-free mats, a 24x24 mat and a 20x20 mat, giving you 4 ways to display artwork in a single frame. The flat black solid wood border and tempered glass front deliver a clean, gallery-quality presentation that protects your print for years.

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 24x24 window and 1 with a 20x20 window
• Mats are acid-free, lignin-free, bevel-cut, 4-ply alpha cellulose for archival-safe display
• Black backboard with back hooks for landscape or portrait hanging

4 Ways to Display

1. No mat: displays a full 27.5x27.5 in. image, ideal for 28x28 square posters
2. Double matted: layer both mats for a framed 20x20 image with a classic double-mat reveal
3. 20x20 mat only: displays a 20x20 image with a wide single mat border
4. 24x24 mat only: displays a 24x24 poster with a clean single mat border

Mats overlap the artwork by 0.25 in. on each edge, so the viewable area is 23.5x23.5 in. with the 24x24 mat and 19.5x19.5 in. with the 20x20 mat.
