What is passport size photo size in cm?

3.5 x 4.5 cm in India, the Schengen area and the UK. The United States is the exception at 5.1 x 5.1 cm, which is 2 x 2 inches.

What is the passport photo aspect ratio?

35:45, which reduces to 7:9, for a 35 x 45 mm photo. The US 2 x 2 inch photo is square, a 1:1 ratio, so the same crop cannot serve both.

How many pixels is a passport size photo?

413 x 531 pixels at 300 DPI for 35 x 45 mm, and 600 x 600 pixels for 2 x 2 inches. Multiply the size in inches by 300 to get the pixel count for any other size.

Why does my correctly sized photo print too large?

The file is being printed at a lower DPI than 300, usually 72. Ask for actual size rather than fit-to-page, or scale to print at 300 DPI.

How much of the photo should the head cover?

About 70 to 80 percent of the height, roughly 32 to 36 mm on a 45 mm tall photo, with the eyes sitting slightly above the middle.

Passport Size Photo Dimensions

Every measurement in one place — millimetres, centimetres, inches and the pixel count at 300 DPI. Find the row that matches your form, then read why the pixel number matters as much as the print size.

Print size and pixel size are not the same thing

This is the confusion that sends most people looking for a dimensions page. A form asks for a 35 × 45 mm photo, the upload box rejects the file, and the error message says nothing about millimetres. That is because a digital file has no physical size at all. It has a pixel count. Millimetres only exist once the file is printed, and how big it prints depends entirely on the DPI the printer is told to use.

The bridge between the two is one line of arithmetic: pixels = inches × DPI. At the 300 DPI photo labs and passport offices expect, 35 × 45 mm becomes 1.38 × 1.77 inches, which becomes 413 × 531 pixels. Send that same file to a printer set to 72 DPI and it spreads across more than four times the paper — the usual reason a lab print refuses to fit the box on the form.

The three standards that cover most forms

India, 35 × 45 mm. The default for the passport itself, Indian visas, and any form that says nothing more specific than "passport size". Portrait, a 7:9 ratio, plain light background, head filling roughly 70 to 80 percent of the height.

United States, 2 × 2 inches. The odd one out, and square: 51 × 51 mm, 600 × 600 pixels, a 1:1 ratio. The State Department also measures the head itself at 1 to 1.4 inches from chin to crown, so an Indian crop pasted into a US application is normally too tight.

Schengen, 35 × 45 mm. The same footprint as the Indian size, which is why one crop often serves both, though consulates are stricter about even lighting and a background with no shadow or texture behind the shoulders.

File size limits are a separate rule

Correct pixels do not guarantee a successful upload. Passport Seva caps JPEGs at 300 KB, and state exam portals often cap at 50 KB or even 20 KB. Set a target size in the maker below and it compresses to fit while keeping the 413 × 531 grid intact, instead of pushing the photo through a second website that quietly resizes it again.
