What size is a 2x2 inch passport photo in mm?

Exactly 50.8 by 50.8 mm. It is often quoted as 51x51 mm, which is a rounding of 0.2 mm per side. That is within tolerance, but the exact figure is 50.8 mm and this site uses the exact value.

What is the Canadian passport photo size in inches?

50 by 70 mm converts to 1.97 by 2.76 inches. Canada publishes only the millimetre figure, so ask a photo lab for 50x70 mm. Requesting 2 by 2.75 inches would produce a photo slightly out of specification.

Should I ask a photo lab for inches or millimetres?

Always give the unit the authority published. For US and Indian documents that is inches; for everything else it is millimetres. Converting and rounding introduces error, and photo tolerances are tight enough that a rounding of half a millimetre per side is worth avoiding.

How many pixels is a 2x2 inch photo?

600 by 600 pixels at 300 DPI, or 1200 by 1200 at 600 DPI. Both are accepted for US online submissions, where the permitted range is 600x600 to 1200x1200. Inches multiplied by DPI gives pixels directly, which is the one place imperial units are genuinely convenient.

Passport photo size in inches

Only the United States and India routinely specify photo sizes in inches. Everywhere else publishes millimetres, so these are exact conversions rather than official figures. Print settings and paper sizes are where inches matter most.

Photo sizes in inches

Converted at 25.4 mm to the inch and rounded to two decimal places. The millimetre column holds the officially published figure.

Where inches actually matter

Two situations. The first is US and Indian documents, where the specification itself is written in inches: a 2 by 2 inch photo with a 1 to 1 3/8 inch head height. The second is printing, because photo paper and lab print sizes are sold in inches almost everywhere, including in metric countries. A 4x6 print is a 4x6 print in Toronto and in Berlin.

That second point is why the print sheet option on this site offers 4x6 and 5x7 inch sheets alongside A4 and Letter. You will be handing the file to a kiosk that thinks in inches even if your photo specification is in millimetres.

Inches convert cleanly to pixels

The one real advantage of an imperial specification is that DPI stands for dots per inch, so pixels follow directly. A 2 inch photo at 300 DPI is 600 pixels. At 600 DPI it is 1200 pixels. No arithmetic required, which is why US digital requirements are stated as neat round numbers while metric ones are not.

Compare that with 35 mm, which needs dividing by 25.4 first, giving 413 pixels at 300 DPI. The awkward numbers you see in metric pixel requirements, like IRCC's 420 by 540, are rounded versions of exactly this calculation.

Do not convert and round

The most common mistake with imperial conversions is compounding a rounding error. If a 35x45 mm photo becomes "about 1.4 by 1.8 inches" and a lab then prints to that, you have 0.6 mm of error on the width and 0.7 mm on the height before the crop is even considered. Photo tolerances do not leave room for that, so quote the published unit.

FAQ

Questions, answered

1.38 by 1.77 inches. This is why the international standard feels awkward in imperial units and why no imperial-first country adopted it. If a US photo lab asks what size you need, ask for 35x45 mm rather than the inch conversion, because rounding to 1.4 by 1.8 inches puts you outside tolerance.
