How to choose the right frame size
- Match the aspect ratio. Pick a frame whose proportion matches your print (2:3, 4:5, etc.) so the image is not cropped.
- Decide on a mat. Add a mat for a gallery look — choose a frame one or two standard sizes larger than the print.
- Scale to the wall. The framed piece should suit the wall and furniture below it. Use the Wall Art Size Calculator for an exact recommendation.
- Preview before you buy. See the exact framed size on a real wall with the frame mockup generator.
If you are preparing the artwork itself, the poster and art-print size guide explains how print size, mat opening, pixels, bleed, and outer frame size differ.
Frequently asked questions
What are the most common standard frame sizes?▾
The most common standard frame sizes (in inches) are 4×6, 5×7, 8×10, 8.5×11, 11×14, 16×20, 18×24, and 24×36. 8×10 and 11×14 are the most widely sold for prints and art, while 18×24 and 24×36 are standard poster sizes.
What size frame do I need for an 11×14 print?▾
An 11×14 print fits an 11×14 frame with no mat. If you want a mat border around it, use a 16×20 frame with an 11×14 mat opening — that gives a roughly 2.5 in mat reveal and a more gallery-like look.
What size frame do I need for an 8×10 print?▾
An 8×10 print fits an 8×10 frame directly. For a matted look, use an 11×14 frame with an 8×10 opening, which leaves about a 1.5–2 in mat border.
Do I need a mat for my frame?▾
A mat is optional, but it adds a clean border, protects the artwork from touching the glass, and makes a piece look more finished. With a mat, you choose a frame one or two standard sizes larger than the print so the mat has room around the image.
What are standard poster frame sizes?▾
Standard poster frame sizes are 18×24, 24×36, and 27×40 inches. In metric (A-series), common poster sizes are A2 (420×594 mm) and A1 (594×841 mm).
What is the difference between frame size and print size?▾
Frame size usually refers to the size of the artwork or mat opening the frame holds — an 11×14 frame holds an 11×14 print (or an 11×14 mat with a smaller opening). Always check whether a listing means the print size or the outer frame size before buying.
What are standard metric (A-series) frame sizes?▾
The international A-series sizes are A4 (210×297 mm / 8.3×11.7 in), A3 (297×420 mm), A2 (420×594 mm), and A1 (594×841 mm). A4 and A3 are the most common for prints and posters outside the US.
How do I know what frame size looks right on my wall?▾
Frame size should suit the wall and any furniture below it — a common rule is artwork spanning 60–75% of the furniture width. Use the Wall Art Size Calculator for an exact recommendation, then preview the framed size in a real room with WallMockup before buying.
