36x48 Poster Frame with 6-Ply Double Mat, Flat Black Solid Wood

This 36x48 frame is built for oversized posters, gallery prints, and large-format photography. It includes 2 acid-free 6-ply mats, a 30x40 mat and a 24x36 mat, giving you 4 ways to display artwork in a single frame. The flat black solid wood border and premium acrylic front deliver a clean, gallery-quality presentation at a scale that glass cannot safely reach.

Key Features

• Premium acrylic front, shatter-resistant and significantly lighter than glass at this size
• Solid wood border in a flat black finish, 1.5 in. wide and 1 in. thick
• 2 included mats: 1 with a 30x40 window and 1 with a 24x36 window
• Upgraded 6-ply mats for a deeper bevel and a more dimensional double-mat reveal
• Mats are acid-free, lignin-free, bevel-cut, alpha cellulose for archival-safe display
• Black backboard with hanging hardware for landscape or portrait orientation

4 Ways to Display

1. No mat: displays a full 35.5x47.5 in. image, ideal for 36x48 posters
2. Double matted: layer both mats for a framed 24x36 image with a deep 6-ply double-mat reveal
3. 24x36 mat only: displays a 24x36 image with a wide single mat border
4. 30x40 mat only: displays a 30x40 poster with a clean single mat border

Mats overlap the artwork by 0.25 in. on each edge, so the viewable area is 29.5x39.5 in. with the 30x40 mat and 23.5x35.5 in. with the 24x36 mat.

Frequently Asked Questions

What sizes can I display in this frame?
You can display 36x48, 30x40, and 24x36 artwork. The 2 included mats let you switch between sizes without buying a new frame.

Does this frame come with mats?
Yes. 2 acid-free 6-ply mats are included: 1 with a 30x40 window and 1 with a 24x36 window. Use them separately, together, or not at all.

What is a 6-ply mat?
A 6-ply mat is thicker than a standard 4-ply mat, creating a deeper beveled edge and a more pronounced border, especially in a double-mat layout.

Are the mats archival quality?
Yes. Both mats are acid-free, lignin-free, bevel-cut, alpha cellulose, safe for long-term contact with prints and photographs.

Is the front glass or acrylic?
This frame uses premium acrylic. At 36x48 in., acrylic is the safer and more practical choice: it resists shattering and weighs far less than glass, which matters for both shipping and wall mounting.

How does the frame hang?
Hanging hardware is included for both landscape and portrait orientation.
