One Of The Largest Passport Photo Formats
5x7cm is physically bigger than most countries' 3.5x4.5cm standard.
Brazil's Polícia Federal requires a 5 x 7cm (50 x 70mm) photo — the same larger physical size used by Canada — rather than the more common 3.5 x 4.5cm ICAO format. Don't reuse a photo sized for another country without recropping.
Within that larger frame, your face (chin to crown) should still measure 31-36mm and occupy roughly 70-80% of the photo's height, with both shoulders visible at the bottom edge.
