Passport photo dimensions
Thirty-five by forty-five millimetres is the most common passport photo size worldwide. This guide covers exact dimensions, pixel counts, country usage, and how Passprint enforces millimetre-accurate crops.
35×45 mm equals 3.5×4.5 cm. At 300 DPI that is 413×531 pixels. Generic editors crop to approximate ratios; passport offices measure the print with a ruler. Pair this page with the passport photo maker and the crop passport photo guide for end-to-end framing. Passprint automates the entire workflow from upload to print-ready sheet in just a few clicks.
Every export uses 35 mm width and 45 mm height at 300 DPI — not approximate ratios that drift when printed.
ICAO Doc 9303 recommends the head occupy 70–80% of the image height. Country presets apply stricter bands on top.
Multiple 35×45 copies align to a precision grid so trim lines stay straight on your cutter.
Use the diagram for millimetre and pixel checks, then compare 35×45 with the square US 2×2 inch and Canadian 50×70 mm standards before you crop.
| Spec | 35×45 mm | 2×2 in (US) | 50×70 mm (Canada) |
|---|---|---|---|
| Outer size | 35×45 mm | 2×2 in (51×51 mm) | 50×70 mm |
| Shape | Portrait rectangle (7:9) | Square | Taller rectangle |
| Typical use | India, UK, Schengen, many others | US passport & visa | Canadian passport |
| Head / face height | Country % / mm bands (often ICAO 70–80%) | 1–1⅜ in (25–35 mm) chin to crown | 31–36 mm face height (IRCC) |
| 300 DPI pixels (approx.) | 413×531 px | 600×600 px | 591×827 px |
| Background | Usually white / light plain | Plain white or off-white | Plain white or light |
Most 35×45 mm destinations expect a plain white or light backdrop with no patterns, shadows, or other people in frame. UK, India, and Schengen rules flag busy walls and coloured curtains. The white background guide covers AI replacement before you lock the 35×45 crop.
Even front light keeps both sides of the face similar in brightness and reduces chin or wall shadows in the 7:9 frame. Avoid strong backlight and beauty filters. Shoot from eye level with headroom so the crop can meet ICAO-style face-height bands.
Typical failures include face height outside the destination band, tilted head, smile, glasses glare, background shadows, soft low-resolution files, and stretched conversions from a square 2×2. Re-crop correctly instead of squashing — see the crop passport photo guide.
Printed 35×45 photos should be sharp at 300 DPI on photo paper. Digital uploads need a JPEG within portal pixel and file-size limits — often around 413×531 px. Export once from the passport photo maker, then downscale only if a form requires a smaller file.
At 300 DPI, 35×45 mm is about 413×531 pixels — the studio default for A4 sheets and most online forms. A high-resolution source keeps ICAO-style framing sharp after crop. See the ICAO guide for Doc 9303 context beyond outer millimetre size.
