MBC MAT BOARD CENTER 11×14 Foam Board Pack

Best for: artists and photographers framing smaller works. The set includes ten white foam boards, each 11×14 inches and 1/8 inch thick. Acid-free cores protect works from acid migration, supporting long-lasting displays. Choose this when you need uniform backing across multiple pieces and want a ready-to-frame supply. Caution: Not ideal for very large projects or frames that require thicker mats.
AXELIP 11×14 Self-Stick Mounting Board (4 Pack)

Best for: quick DIY framing and crafts that require an immediate backing. The 11×14 boards are 2 mm thick and include self-stick backing, enabling straightforward mounting without glue. They’re useful for cross stitch projects or photo frames where a strong, flat backing is essential. Limitation: self-stick surfaces may not be suitable for all paper types or long-term archival needs.
Navy Penguin 24×36 Foam Board (12 Pack)

Best for: large posters, canvases, and gallery-ready pieces. The 36×24 inch boards are 3/16″ thick and acid-free, offering a stable surface for mounting big artworks. The 12-pack ensures consistent backing for multiple large frames. Caution: Large boards can be bulky to transport and store, and edge protection is important during shipping or handling.
Navy Penguin 12×16 Foam Board (12 Pack)

Best for: compact frames, school projects, and craft displays. The 12×16 boards are 3/16″ thick, double-sided, and acid-free, making them versatile for both backings and presentations. Choose this if you frequently work with standard 8×10 or 11×14 frames and want a consistent, archival-friendly option. Limitation: May be too small for truly large works without cutting or joining pieces.
AYAYGD 12 x 16.5 Foam Core 3/16″

Best for: classrooms, studios, and hobbyists seeking a budget-friendly option. This 12×16.5 inch board uses a 3/16″ thick, polystyrene core with acid-free coating, designed for easy cutting. It’s a solid choice for projects where cost matters but a clean, white display surface remains important. Caution: Availability of sizes may vary; check compatibility with your framing dimensions.
Buying Guide: Foam Board For Framing
- What size should I choose? Consider standard frame sizes (8×10, 11×14, 16×20) and whether you need mats or full-back framing. Larger boards provide more mounting options but are harder to trim precisely.
- Does the board need to be acid-free? For archival quality and long-term display, select acid-free cores to prevent discoloration and damage to artwork over time.
- What thickness is best? Thinner boards (about 1/8″) are lighter and easier to cut; thicker boards (3/16″ or 2 mm) offer better rigidity for heavier pieces or larger formats.
- Self-stick vs. tape-backed backing: Self-stick mounting boards simplify mounting but may not suit all media. Tape-backed or standard glue methods provide flexibility for fragile materials.
- One-pack vs. multi-pack: For bulk projects or classrooms, multi-packs ensure color and thickness consistency across pieces and keep your workspace organized.
- Storage and handling: Store flat to prevent warping. Use edge protectors during transport to avoid denting or bending the boards.
