How to Measure a Poster for a Frame (Avoid the Sizing Mistake)
Buying the perfect frame should be exciting—not frustrating. Yet one of the most common mistakes people make is choosing the wrong frame size because they measure their poster incorrectly.
The good news? Measuring a poster only takes a few minutes, and it can save you time, money, and unnecessary returns.
Why Accurate Measurements Matter
A frame that's too small won't fit your poster, while a frame that's too large can leave awkward gaps. Taking accurate measurements ensures your artwork looks clean, professional, and ready to display.
Step 1: Measure the Poster Itself
Lay your poster on a flat surface and use a tape measure or ruler.
Measure:
Width (left to right)
Height (top to bottom)
Always measure the "actual paper" not the rolled-up packaging or shipping tube.
Step 2: Check if There's a White Border
Some posters include a white border around the artwork. Decide whether you want the border to remain visible or be covered by the frame or mat.
This small detail can affect the frame size you choose.
Step 3: Decide if You Want a Mat
A mat adds space between the poster and the frame, creating a more elegant appearance. If you're using one, you'll need a larger frame than the poster itself.
For example:
* Poster: 18 × 24 inches
* With a mat: 24 × 30-inch frame
The #1 Sizing Mistake to Avoid
Many people measure the **outside dimensions of an old frame** instead of the poster itself.
Frame sizes are based on the **artwork dimensions**, not the frame's outer edges. Always measure the poster first before shopping for a replacement frame.
Common Poster Frame Sizes
Some of the most popular sizes include:
* 11 × 17 inches
* 16 × 20 inches
* 18 × 24 inches
* 24 × 36 inches
* 27 × 40 inches
If your poster has custom dimensions, consider ordering a custom-made frame for the best fit.
Final Thoughts
Learning how to measure a poster for a frame is simple, but it makes a huge difference in the final result. Measure the width and height carefully, account for any borders or mats, and always choose your frame based on the poster's actual size.
With the right measurements, your favorite artwork will look polished, protected, and ready to enjoy for years to come.
