2×2 inch standard
The United States requires 2×2 inch (51×51 mm) square photos with the head measuring 1–1⅜ inches (25–35 mm) from chin to crown. This guide covers dimensions, pixels, and how Passprint applies head-size framing.
Cropping to a square is not enough — US guidelines measure head height in inches. Passprint combines 51×51 mm dimensions with face-detection framing. Use this page with the US passport guide, the passport photo maker, and the crop how-to when you need end-to-end framing. Passprint automates the entire workflow from upload to print-ready sheet in just a few clicks.
Face detection centres the head and scales it to the percentage US passport and visa guidelines describe.
Export a JPEG at 600×600 pixels (300 DPI) for government portal uploads.
Lay out several 2×2 copies per page for walk-in studio clients who need prints immediately.
Use the diagram for millimetre, inch, and pixel checks, then compare 2×2 with the rectangular 35×45 mm and Canadian 50×70 mm standards before you crop.
| Spec | 2×2 in (US) | 35×45 mm | 50×70 mm (Canada) |
|---|---|---|---|
| Outer size | 2×2 in (51×51 mm) | 35×45 mm | 50×70 mm |
| Shape | Square | Portrait rectangle | Taller rectangle |
| Typical use | US passport & visa | India, UK, Schengen, many others | Canadian passport |
| Head / face height | 1–1⅜ in (25–35 mm) chin to crown | Country % / mm bands (often ICAO-aligned) | 31–36 mm face height (IRCC) |
| 300 DPI pixels (approx.) | 600×600 px | 413×531 px | 591×827 px |
| Background | Plain white or off-white | Usually white / light plain | Plain white or light |
US passport and visa photos expect a plain white or off-white backdrop with even tone and no patterns, shadows, or other people in frame. Busy walls and coloured curtains are common rejection triggers. After capture, the white background guide explains how Passprint replaces imperfect walls with a uniform tone before you lock the 2×2 crop.
Even front light keeps both sides of the face similar in brightness and reduces chin or wall shadows that survive into the square frame. Avoid strong backlight and beauty filters. Shoot from eye level with a little headroom so the crop can meet the 1–1⅜ inch head band without cutting the crown or ears.
Typical failures include head height outside the 1–1⅜ inch band, tilted head, smile or open mouth, glasses glare, shadows on a white wall, low resolution soft files, and stretched conversions from 35×45. Re-crop with correct framing instead of squashing a rectangle into a square — the crop passport photo guide covers that workflow.
Printed 2×2 photos should be sharp at 300 DPI on photo paper for counters and renewals that still use hard copies. Digital uploads (including many DS-160 flows) need a square JPEG that meets portal pixel and file-size limits — often around 600×600 px. Export once from Passprint, then downscale only if a form requires a smaller file.
At 300 DPI, 2×2 inches is 600×600 pixels. That is the practical studio default for print sheets and most online forms. Starting from a high-resolution portrait helps ICAO-style face framing stay sharp after crop. Pair this size guide with the ICAO guide when you need international framing context beyond US inch measurements.
