How to use the converted dimensions

Check the usable opening
Before buying a frame, confirm its opening and mat dimensions rather than relying only on the label.
Conversion answers
Photo inches to centimeters FAQ
How do I convert photo sizes from inches to centimeters?

What is a 4 × 6 inch photo in centimeters?
The exact conversion is 10.16 × 15.24 cm. Retail products may use the rounded label 10 × 15 cm.
Should I swap width and height for a portrait photo?
No. Enter the dimensions in the order you measured them. A 4 × 6 landscape photo and a 6 × 4 portrait photo contain the same side lengths in a different order.
