Why this size

Resize image in inches: inches to pixels at 300 DPI

At 300 DPI, the print standard, each inch needs 300 pixels: a 4 x 6 inch print is 1200 x 1800 pixels and a 2 x 2 inch photo is 600 x 600. The tool converts your inches to pixels and writes 300 DPI into the file, so printers use the size you typed.

To find the size in inches of a photo you already have, divide its pixels by its DPI: a 3000 x 2000 pixel photo at 300 DPI prints at 10 x 6.67 inches. The common sizes have their own pages with the size already set: 4x6, 5x7, wallet size, US Letter, the 2 x 2 inch passport photo and the 3.37 x 2.13 inch ID card size.
