How to Frame a Poster | Keep It Flat & Damage-Free

Frame a poster by measuring it, choosing a matching or slightly larger frame, mounting it with acid-free materials, and hanging it at eye level.

Nothing ruins a great concert or movie poster faster than a sloppy framing job. Wrinkles, tape marks, and cloudy glass turn art into clutter. The fix for all of it takes about thirty minutes and a handful of the right materials. Whether you are preserving a vintage print or showing off a new purchase, the process below works for any size.

What Size Frame Do I Need For A Poster?

Measure the poster first, then match the frame to it. Standard poster sizes are 18×24 inches, 24×36 inches, and 27×40 inches, with 27×40 commonly cited as the standard for official movie posters. A frame that is slightly larger than the poster also works well and can create a matted look.

If your print lands on an odd size, order a custom frame or use a mat to bridge the gap. Buying a frame that is too small never ends well. For a popular common size like 16×20, a roundup of quality wood 16×20 poster frames can save you a bad purchase.

Preparing The Poster And The Frame

Good prep prevents most framing mistakes. Work on a clean, flat surface and wash your hands first—oils from your skin transfer straight onto paper and glass. If the poster arrived curled up from shipping, flatten it under heavy books for about 24 hours before you touch the frame.

Take the frame apart completely and clean the glass on both sides before reassembling. Dust and fingerprints sealed inside a frame are nearly impossible to remove later. A streak-free glass cleaner and a lint-free cloth handles the job.

Mounting The Poster Without Damaging It

The mounting step decides how the poster looks in five years. Place the poster face-down on the backing board and secure it with acid-free tape along the top edge only. This top-edge hinging lets the print hang naturally without buckling.

Never use regular tape, glue, or any adhesive directly on the print. Standard tape yellows and stains, and glue can warp the paper permanently. Acid-free or archival materials cost a little more and protect the print over time. A stable backing board also keeps the poster flat so it does not ripple inside the frame.

Once the poster sits correctly on the backing, sandwich it into the frame, seal the back, and stand back to check for visible dust before you hang it.

Hanging And Placement Pointers

Where you hang the frame matters as much as how you build it. A common gallery standard places the center of the artwork about 57 inches from the floor; other guides suggest 57–60 inches at eye level. Above a sofa, hang it 6–8 inches above the backrest so it reads as connected to the furniture.

Pick the hardware based on the frame’s weight. Lightweight frames work fine with sawtooth hangers, while heavier or larger frames need stronger systems like D-rings or wall cleats so they stay put.

Finally, keep the poster out of direct sunlight. UV rays fade colors over time, and the heat can also dry out and yellow the paper. Display it on a wall that gets indirect light, and use quality glazing that protects the print without the fragility of plain glass.
