A US passport photo is square: 2 x 2 inches, or 51 x 51 mm. Within that square the head has to fall inside a specific size and position range, which is where most home-made photos go wrong. Always confirm the current rules with the US Department of State before submitting.
A US passport photo is square, unlike the rectangular format most of the world uses. The figures below are the ones that matter when cropping.
| Requirement | Specification |
|---|---|
| Photo size | 2 x 2 in (51 x 51 mm) |
| Head height | 25-35 mm (chin to crown) |
| Background | Plain white or off-white |
| Minimum resolution | 300 DPI for a printed photo |
| Digital resolution | 600 x 600 pixels minimum, at 300 DPI |
| Eye height from the bottom edge | 1 1/8 to 1 3/8 in (28-35 mm) |
| Colour | Colour, not black and white |
| Age of photo | Taken within the last 6 months |
| File format for online submission | JPEG |
Head size and eye position are where most home-made US photos fail, and they are not the same as centering your face in the frame. Within a 2-inch square, the head from chin to the top of the head has to measure between 1 and 1 3/8 inches — so roughly 50% to 69% of the image height — with the eyes between 1 1/8 and 1 3/8 inches up from the bottom edge.
In practice that means a head-and-shoulders framing with visible space above the head, not a tight crop on the face. Selecting the United States in the passport photo tool applies these ratios to your crop.
For a paper application, print at 2 x 2 inches on photo-quality paper — most print services offer a 4 x 6 sheet that fits several copies. For an online application, submit the JPEG at 600 x 600 pixels or larger.
Requirements differ for children, for visas, and for other travel documents, and the official guidance is the authority on all of them. Check the US Department of State photo requirements before submitting, and if a photo is rejected, that is also where the reason will be explained.
2 x 2 inches, equivalent to 51 x 51 mm — a square, unlike the 35 x 45 mm rectangle used by many other countries. At 300 DPI that is 600 x 600 pixels.
Measured from the bottom of the chin to the top of the head, between 1 inch and 1 3/8 inches (25–35 mm), with the eyes roughly between 1 1/8 and 1 3/8 inches from the bottom of the photo.
A plain white or off-white background with no shadows, patterns, or objects behind you. Even lighting from the front avoids the shadow that causes many rejections.
Glasses are not accepted except with a signed medical note. Remove them for the photo rather than risk a rejection over glare or frames covering the eyes.
The most common reasons are shadows on the face or background, wrong head size or position, a non-neutral expression, glasses, low resolution, and digital retouching. Check each of those before submitting.
