How the Nigerian passport photo process works
A Nigerian passport photo is 35×45 mm — at least 600×600 px for a digital file — on a plain white background with no shadows, taken to spec and submitted with your application to the Nigeria Immigration Service. The face should fill around 70% of the frame, visible ear to ear and forehead to chin, with roughly 3 mm of space above the hair, a neutral expression and no glasses. Nigeria is notably strict that the photo be very recent. Snapfora crops and sizes to 35×45 mm locally and flags head height and tilt, so you fix problems before you submit rather than after a rejection. It builds to the published spec but cannot guarantee acceptance — the issuing authority decides.
