US vs UK poster sizes
US poster sizes are imperial and don't match A sizes exactly — an 18x24 poster is close to (but not the same as) A2, and 24x36 sits between A1 and A0. This matters when framing: a frame made for A1 will not correctly fit a 24x36 poster. If you own posters from both systems, made-to-measure framing avoids the mismatch entirely.
Framing a poster
Posters are printed on thinner paper than art prints, so framing does two jobs: it flattens and protects the poster, and it upgrades how it reads on the wall. A mat border can make even a mass-printed poster look gallery-hung. Browse poster frames made to any of the sizes above — or any size in between — and see our large picture frames for 24x36 and up. You can also print your own poster at any size, with or without a frame.
Frequently asked questions
What is the standard poster size?
24 x 36 inches in the US; A1 (59.4 x 84.1 cm) is the closest standard poster size in the UK and Europe.
What size are movie posters?
Modern cinema "one-sheet" posters are 27 x 40 inches (69 x 102 cm). Older and international movie posters vary — measure before buying a frame, or have a frame made to the exact size.
What size frame do I need for a 24x36 poster?
A frame made for a 24 x 36 inch print. Avoid "approximate fit" frames — a poster that's loose in its frame ripples over time. A made-to-measure poster frame holds the sheet exactly.
