This 20x20 square frame is built for posters, gallery prints, and large-format photography. It includes 2 acid-free mats, a 16x16 mat and a 12x12 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 16x16 window and 1 with a 12x12 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 19.5x19.5 in. image, ideal for 20x20 square posters
2. Double matted: layer both mats for a framed 12x12 image with a classic double-mat reveal
3. 12x12 mat only: displays a 12x12 image with a wide single mat border
4. 16x16 mat only: displays a 16x16 poster with a clean single mat border

Mats overlap the artwork by 0.25 in. on each edge, so the viewable area is 15.5x15.5 in. with the 16x16 mat and 11.5x11.5 in. with the 12x12 mat.
