Official sizes for the US, UK, Australia and New Zealand
Passport photo size, to the millimetre.
A US passport photo is 2 × 2 inches. UK, Australian and New Zealand photos are 35 × 45 mm. The size is the easy part: the head has to fill the right share of it, and that’s what gets photos rejected.
US Passport: 2 × 2 in (51 × 51 mm), with 1–1⅜ in from the chin to the top of the head.

Passport photo sizes by document.
The printed size, how big the head must be, and the file online forms ask for. Online applications don’t all want the same crop as a print.

In every unit

Photo labs print at 300 dots per inch, so that’s the pixel size we use. A standard 4 × 6 in photo print is the cheapest way to get them.

Why size isn’t enough
Same size. Three heads.
All three are exactly 2 × 2 in (51 × 51 mm). Only one has the head the US Passport asks for. That’s why we don’t let you drag the crop: we find the top of your head and your chin, and crop to fit.
Cropped too loose, often because the phone was too far away.
1–1⅜ in (25–35 mm) from the chin to the top of the head.
Cropped too tight, often because the phone was too close.
Questions
Good to know.
What size is a passport photo?
It depends on the country. A US passport photo is 2 × 2 inches (51 × 51 mm), and so are US visa and Green Card photos. UK, Australian and New Zealand passport photos are 35 mm wide and 45 mm high. The head has to fill a set share of the photo too: 1 to 1⅜ inches from the chin to the top of the head for the US, 29 to 34 mm for the UK.
Is 2 × 2 inches the same as 51 × 51 mm?
Yes. Two inches is 50.8 mm, which the US State Department rounds to 51 mm. In centimetres that’s about 5 × 5 cm.
How many pixels is a 2 × 2 passport photo?
600 × 600 pixels at 300 dpi, the resolution photo labs print at. That’s also the file we give you for the US visa form (DS-160): a square JPG under 240 KB. An online US passport renewal takes a JPG, PNG or HEIC file between 54 KB and 10 MB.
What size is a UK passport photo?
Printed, 45 mm high and 35 mm wide, with 29 to 34 mm from your chin to the top of your head. Applying online, GOV.UK wants a digital photo of at least 600 × 750 pixels that you haven’t cropped, because it crops it for you. We give you that file too.
How do I print a passport photo at the right size?
Print at 100% or “actual size”, never “fit to page”, and measure one photo with a ruler before you cut. A 4 × 6 in photo print holds six 2 × 2 in photos (printed borderless) or eight 35 × 45 mm ones. For the UK, Australia and New Zealand, use a photo lab: Australia and New Zealand don’t accept inkjet prints, and the UK asks for a professional print.
Can I just crop any photo to passport size?
Only if the head ends up the right size. Cropping to 2 × 2 in or 35 × 45 mm is the easy part; a head that’s too small or too big for the frame is a common reason home-made photos are rejected. PassFino finds the top of your head and your chin and crops to fit your document, then checks the rest for free.
