US Passport Photo Head Size Guide (1–1⅜ in / 25–35 mm)

The Exact Rule: 1 to 1⅜ Inches (25–35 mm) Chin to Crown

The U.S. Department of State requires that the head height in a passport photo — measured from the bottom of the chin to the top of the skull (not the top of the hair) — fall between 1 inch and 1⅜ inches (25 mm to 35 mm). The overall photo must be 2×2 inches (51×51 mm), so your head should occupy roughly 50% to 69% of the total frame height.

That range is deliberate. A head that is exactly 1 inch tall in a 2-inch photo takes up exactly 50% of the height, which is the minimum. A head that is 1⅜ inches tall takes up about 69% of the height, which is the maximum. Both ends of the range are acceptable — anything outside them is not.

Why does this matter for online renewal? The State Department's online portal runs automated checks on uploaded photos. Head size is one of the first things those checks evaluate. A photo that is slightly too zoomed-in (head too large) or slightly too far back (head too small) will be flagged before your application even reaches a human reviewer. Resubmitting costs time and can delay your renewal.

How to Measure Chin to Crown

Measuring head height in a photo sounds straightforward, but the definition of "crown" trips up many applicants.

Crown means the top of the bony skull, not the top of the hair. If you have thick, voluminous hair, fluffy curls, or a high bun, the top of your hairstyle may sit an inch or more above your actual skull. The State Department measures to the skull, so a large hairstyle does not count toward your head height. In practice, this means people with tall hairstyles need to leave extra space above their head in the frame — the cropped photo may look like it has a lot of "empty space" at the top, but that space is needed to keep the head within bounds when the measurement is taken at the skull.

Afros and natural hair that grows outward, rather than upward, are treated similarly: the measurement is chin to skull, not chin to outermost hair.

How to measure in practice:

1. Print the photo at 2×2 inches (or view it at 100% scale in an image editor at 2-inch canvas size).
2. Place a ruler vertically against the photo.
3. Mark the lowest visible point of the chin and the highest point of the skull (not the hair).
4. Read the distance. It must be between 1 inch and 1⅜ inches.

In pixels at 300 DPI — the standard for a 2×2 photo — a 600×600 pixel image corresponds to 2×2 inches. In that coordinate space, 1 inch = 300 pixels and 1⅜ inches = 413 pixels. So the chin-to-crown pixel height must fall between 300 px and 413 px at 300 DPI. Online tools like the PhotoPass checker handle this conversion for you automatically.

Common Framing Errors That Cause Rejection

Head size violations are among the most common reasons passport photos are rejected. Here are the specific mistakes to avoid:

Standing Too Close to the Camera (Head Too Large)

This is the most frequent error when people take selfies for passport purposes. When the phone is held at arm's length and pointed slightly upward, the face fills most of the frame. After cropping to 2×2, the head often exceeds the 1⅜-inch maximum. The photo looks fine to the eye — your face is clear and well-lit — but the head proportion fails the automated check.

Standing Too Far from the Camera (Head Too Small)

The opposite problem occurs when someone tries to avoid the "too close" trap and backs up too far. A 2×2 crop of a distant shot produces a head that is under 1 inch, which is below the minimum. Small heads also tend to suffer from pixelation when cropped and enlarged.

Selfie Arm Distortion

Holding a phone 12–18 inches from your face introduces perspective distortion. The camera is physically close to your forehead and far from your chin, which subtly distorts facial proportions. The State Department recommends having another person take the photo from a distance of 4–5 feet. At that distance, distortion is negligible.

Tilting the Head

Any significant tilt — chin up, chin down, or tilted to one side — changes the effective chin-to-crown measurement along the vertical axis of the photo. Even a 10–15 degree tilt can push a borderline photo out of spec. Keep your gaze level and your head upright, facing directly into the camera.

Cropping at the Wrong Point

Even if the raw photo has good proportions, incorrect cropping afterward can create violations. Cropping too tightly at the top (cutting into the skull) or leaving too much headroom (pushing the head too far down) both affect the chin-to-crown measurement in the final 2×2 frame. Some cropping tools let you drag the crop box manually, which introduces human error. Automated tools that detect facial landmarks and apply the correct crop are more reliable.

Hair Adding Apparent Height

As noted above, tall hairstyles are not counted in the head height measurement. However, they do affect how the photo needs to be framed. If you crop a photo so that your hair fills the top of the frame, the skull may actually be too high in the frame, leaving insufficient space at the bottom and causing the chin to be cut off or too close to the bottom edge. The result is a technically non-compliant crop even though the intent was to "use all the space."

How to Get It Right

The most reliable path to a compliant head size is:

1. Take the photo at the right distance. Have someone else take the photo from 4–5 feet away with the camera at eye level. Use a plain white or off-white background. Look straight ahead with a neutral expression.
2. Use an automated checker to measure head size. The PhotoPass checker analyzes your uploaded photo, detects chin and crown positions, calculates head height in the 2×2 frame, and tells you whether it falls within the 1 to 1⅜-inch range. If it doesn't, the tool flags the specific problem so you know whether to retake from farther back or closer.
3. Let the tool crop, not you. Once the checker confirms the proportions are acceptable, use it to generate the final cropped and sized 2×2 JPEG ready for upload. Manual cropping in photo apps introduces the risk of human error on framing.
4. Use the renewal page for end-to-end guidance. The PhotoPass US passport photo for online renewal page walks through every requirement — background, lighting, expression, head size, file format, and file size — so you can prepare the complete photo in one place.

Frequently Asked Questions

Does the measurement include the chin itself?

Yes. "Bottom of chin" means the lowest visible point of your jaw in the photo, which is the underside of the chin. The measurement runs from there to the top of the skull.

What if my head is naturally large or small?

Head size is measured in the photo, not in real life. If your skull is large, you simply stand farther from the camera to reduce its apparent size in the frame. If your skull is small, step a bit closer. The key is that the photo proportions are what matter, and those are controlled by camera distance and cropping.

Can I zoom in digitally after taking the photo?

Digital zoom degrades image quality and can result in a pixelated photo that is rejected for quality reasons even if the head size is correct. It is better to adjust physical distance from the camera and retake.

Does this rule apply to all U.S. passport applications, not just online renewal?

Yes. The 1 to 1⅜-inch chin-to-crown rule applies to all U.S. passport photos — in-person applications, mail-in renewals, first-time adult passports, and child passports alike. The online renewal portal simply automates the check that a human reviewer would otherwise perform.

My child's head is smaller. Do the same measurements apply?

Yes, the same 1 to 1⅜-inch rule applies to child passport photos. Because children's heads are smaller in absolute terms, the camera may need to be closer than you'd use for an adult, or the photo cropped more tightly. An automated checker is especially helpful here since eyeballing proportions for small faces is difficult.
