Poster Framing Guide: Mats, Mouldings and Glazing Explained

Framing is where a $30 poster starts reading like a $300 artwork. The good news: because every MerchFuse print ships in standard sizes (see the size guide), you can skip custom framing entirely and still get gallery results. Here's the decision path a professional framer walks.

Step 1 — Mat or no mat

A mat (the cream border between print and frame) does three jobs: it gives the composition air, it physically separates paper from glazing, and it bridges sizes — an 18×24 print in a 3-inch mat fills a 24×30 frame. Width rules of thumb: 2 inches for prints up to 16×20, 3 inches for 18×24 and up, and always slightly more at the bottom if you're weighting the mat traditionally. Choose acid-free (museum) matboard; regular board yellows and can burn a brown line into the print over a decade.

Step 2 — Frame profile and color

Thin profiles (under 1 inch) keep attention on the art and suit modern, photographic and minimal work. Wider wood mouldings add weight that flatters vintage advertising and classical pieces. On color: black is the universal sharpener, white disappears into light walls (great for airy O'Keeffe florals), and natural oak or walnut warms botanical and Japanese subjects. Metallic golds belong with genuinely ornate art — on a modern poster they read as costume.

Step 3 — Glazing: glass vs acrylic

Glazing choices matter more than most buyers realize. Standard glass is cheap and scratch-resistant but heavy and dangerous when large. Framing acrylic is half the weight, shatterproof and typically filters more UV — the main cause of fading covered in our print care guide. Upgrade paths: UV-filtering grades (blocking ~98%) for anything in direct light, and museum/anti-reflective coatings when glare kills the view. For prints 24×36 and larger, acrylic isn't a preference, it's physics.

Step 4 — Assembly details framers sweat

• Hinging, not gluing: attach the print to the mat with two acid-free T-hinges at the top only, so paper can expand with humidity.
• Backing: acid-free foam board, never cardboard (it's acidic and attracts pests).
• Dust seal: kraft paper taped across the frame back keeps insects and dust out.
• Hardware: D-rings and coated wire rated at 2–3× the frame weight; sawtooth hangers only under 11×14.

The smart-budget order

If you're allocating a fixed budget: standard-size frame first, acid-free mat second, UV acrylic third, fancy moulding last. Presentation quality comes from the mat and glazing; the moulding is jewelry.
