How the U.S. passport photo process works
For a paper U.S. passport application, print a 2×2 inch photo (51×51 mm), with 1–1⅜ inches (25–35 mm) from chin to top of head. Take the photo within the last six months against a real plain white or off-white background. Snapfora prepares a print crop and provides estimated positioning guides; check the head size yourself. Online passport renewal uses a separate upload process: keep the original unedited digital photo and reposition or crop it in the official renewal application. The issuing authority decides whether the photo is acceptable.
