Photo ID Size Calculation

1. Photo dimensions are measured in inches, where 1 inch = 2.54 cm. Typically, "X-inch" refers to the length of the longer side of the photo in inches.

2. For example: A 5-inch photo has a width of 2.54 × 5 = 12.7 cm; a 12-inch photo has a width of 2.54 × 12 = 30.5 cm.

3. Photo specifications generally refer to the physical dimensions of the photo, specifically its width and height. Different specifications are suitable for different applications, such as family photo albums, ID photos, posters, and more.
