Print Unit Resizing & Passport FAQ Guide

To convert inches or centimeters to digital pixels, multiply the measurement in inches by your target DPI (Dots Per Inch). For metric units, divide centimeters by 2.54 first (1 inch = 2.54 cm) or millimeters by 25.4, then multiply by DPI. Our browser tool computes exact raster pixels automatically and renders your photo locally via HTML5 Canvas at 300 DPI.

Continuous-tone photographic prints require 300 DPI (Dots Per Inch) as standard. At 300 DPI, individual ink droplets blend seamlessly to the human eye. For a standard 2×2 inch US passport photo, 300 DPI produces exactly 600×600 pixels. For a 4×6 cm international passport, 300 DPI produces 472×709 pixels.

US Passports, Visas, and Green Cards require 2×2 inches (51×51 mm, or 600×600 px at 300 DPI) with a compressed size below 240 KB. Schengen Member States and Vietnam Visas require 4×6 cm (472×709 px). UK HMPO, Canadian, and Australian Visas require 3.5×4.5 cm (413×531 px).
