The 2×2 inch standard
US passport photos must be 2×2 inches, equal to 51×51 mm and 600×600 pixels at 300 DPI. Print math is simple: 2 inches multiplied by 300 dots per inch gives 600 pixels per side.
Getting the pixel count and DPI right means a photo lab or home printer produces a correctly sized print. Everything is resized locally, so your passport headshot never leaves your device before you print or upload it.
Composition rules for US photos
The photo needs a plain white or off-white background with even lighting and no shadows. Your head, from the bottom of the chin to the top of the hair, should measure between 1 and 1 and 3/8 inches, roughly 50 to 69 percent of the frame height.
Face the camera straight on with a neutral expression and both eyes open. Resizing to 2×2 inches sets the frame; correct head size and background keep the photo from being rejected.
