Passport Photo Size Maker (2 x 2 in and 35 x 45 mm)

Passport photo dimensions

Passport and ID photos use fixed print sizes. This preset sets the pixel dimensions that match them at 300 dpi, which is the standard print resolution:

• US 2 x 2 inches works out to 600 by 600 pixels at 300 dpi.
• UK and EU 35 x 45 mm works out to 413 by 531 pixels at 300 dpi.

Pick the size, then use cover so the photo fills the frame and the overflow is cropped, or fit to keep the whole photo with padding. Save as JPG, which is what most photo printers and online applications expect.

Size, in mm, inches, and pixels

Most of the search traffic here is really one question: how many pixels is my passport size? Here are the two common formats side by side, in every unit, at 300 dpi.

Format	Millimeters	Inches	Pixels at 300 dpi
US passport	51 x 51 mm	2 x 2 in	600 x 600
UK / EU / most of the world	35 x 45 mm	1.38 x 1.77 in	413 x 531

So 35 x 45 mm is about 1.38 by 1.77 inches, and at print resolution that is 413 by 531 pixels. The US 2 x 2 inch size is 51 x 51 mm, or 600 by 600 pixels.

Passport size photo by country

"Passport size photo" means different things in different countries. Most of the world uses 35 x 45 mm, the United States uses a square 2 x 2 inch, and a few countries go their own way. Here is what the passport size photo comes to in pixels for each, at the standard 300 dpi print resolution.

Country	Millimeters	Inches	Pixels at 300 dpi
United States	51 x 51 mm	2 x 2 in	600 x 600
United Kingdom	35 x 45 mm	1.38 x 1.77 in	413 x 531
India	35 x 45 mm	1.38 x 1.77 in	413 x 531
EU and Schengen visa	35 x 45 mm	1.38 x 1.77 in	413 x 531
Australia	35 x 45 mm	1.38 x 1.77 in	413 x 531
Japan	35 x 45 mm	1.38 x 1.77 in	413 x 531
Canada	50 x 70 mm	1.97 x 2.76 in	591 x 827
China	33 x 48 mm	1.30 x 1.89 in	390 x 567

The 35 x 45 mm preset above covers every row in that group, which is most of the list. For Canada or China, resize by exact pixels on the home page using the numbers in this table.

If a form asks for 600 dpi instead of 300, double every pixel figure: US becomes 1200 x 1200, and 35 x 45 mm becomes 827 x 1063.

Passport photo file size in KB

Getting the dimensions right is only half of an online application. Most upload forms also cap the file size, and they reject the photo without saying which rule it broke.

The common caps are 20 KB to 50 KB for Indian government portals, around 240 KB for the US DS-160 visa form, and 1 MB or less for most other online applications. A 413 x 531 JPG usually lands near 60 to 120 KB straight out of a phone camera, so you often need to bring it down.

Set the pixel size here first, then take the result to the file-size page you need:

• Resize to 20 KB for the tightest Indian portal limits
• Resize to 50 KB for most government upload forms
• Resize to 100 KB for general online applications
• Resize to 200 KB for the DS-160 and similar

Do it in that order. Resizing the pixels after you have hit a KB target will push the file size back up and you will be doing it twice.

How the pixel size is worked out

Pixels come from two things: the physical size and the dpi (dots per inch). The math is simple once you see it: inches x dpi = pixels. A 2 inch side at 300 dpi is 2 x 300 = 600 pixels. For a size given in millimeters, divide by 25.4 to get inches first: 35 mm / 25.4 = 1.38 in, then 1.38 x 300 = 413 pixels. That is why this preset outputs 600 x 600 and 413 x 531. If an authority asks for a different dpi or a slightly different print size, resize by exact pixels on the home page instead.

Important

ResizePad sets the pixel size only. Official passport photos also have strict rules about head size and position, a plain light background, expression, and lighting. This tool does not check those. Confirm the exact requirements with the issuing authority, frame your shot to meet them, and use this preset to get the final pixel dimensions right. If you need to reframe, crop the photo first, then apply the preset.
