Official 2×2 inch passport photo specifications and lighting rules
Use an evenly lit white or off-white background with no distracting shadows. Face the camera directly with a neutral expression and both eyes open; avoid filters, retouching, and perspective distortion.
For U.S. photos, head height from chin to top of hair should generally be 1–1⅜ inches, with eye height about 1⅛–1⅜ inches from the bottom. The oval is a framing aid—not automated biometric validation.
