Picture Frame Sizes
Standard picture frame sizes and the matching mat opening sizes.
Standard frame sizes and the photo each one fits with a mat. The mat opening is slightly smaller than the print so the edges are held in place.

Frequently asked questions
Are frame sizes the same in every country?
No. The US, UK and Europe use different standard sizes, so check the chart for your region and the product’s own measurements.
Why do inches and centimeters not match exactly?
Products are made to round numbers in one system, so the other system’s figures are rounded conversions.
