Passport size photo size in cm, mm, inches and pixels
A passport size photo is 3.5 cm wide and 4.5 cm tall (35 × 45 mm), about 1.38 × 1.77 inches. India's passport application booklet uses the same size, asking for a "passport size photograph (4.5 cm length x 3.5 cm width)".
In pixels it depends on resolution. At 300 dpi, the usual print setting, 3.5 × 4.5 cm is 413 × 531 pixels, and that is what this page saves. Upload forms that only set a KB limit accept this size; enter the limit in Max file size (KB) and the file is compressed to fit.
