Passport photo size in pixels, cm and inches

Updated 26 October 2026 · 13 min read

Short answer

A US passport photo is a 2 x 2 inch square: 600 x 600 pixels at 300 DPI. The other common passport size is 35 x 45 mm (3.5 x 4.5 cm), used for UK passports, Schengen visas and Indian passport prints: 413 x 531 pixels at 300 DPI, or 276 x 354 at 200 DPI. When an online form sets its own pixels, use those: 600 x 600 to 1200 x 1200 for a US visa, at least 600 x 750 for a UK passport, 630 x 810 for an Indian passport.

Passport photo size depends on the country. The US 2 x 2 inch square is 51 x 51 mm, as the State Department writes it. The 35 x 45 mm photo is 3.5 x 4.5 cm, or about 1 3/8 x 1 3/4 inches (1.38 x 1.77 in), and it is the smallest size Ireland and Australia accept. Canada uses 50 x 70 mm, and a Chinese visa photo is 33 x 48 mm. Below are the sizes by country with their official upload rules, what “passport size” means in the US, India and the UK, the head size that goes with each frame, the formula for turning millimeters into pixels, and what DPI does and does not change.

Passport photo size by country in cm, inches and pixels

A print size only becomes a pixel size once you pick a print resolution, measured in DPI: dots, or pixels, per inch. This table converts each printed size an official page gives at 300 and 600 DPI, and adds the pixel size the office sets for an online upload, where it sets one. The link in each country row goes to the official page the numbers come from.

Country or document	In cm	In inches	Pixels at 300 DPI	Pixels at 600 DPI	Official upload size	Make or check it
US passport (State Department)	5.08 x 5.08 cm (51 x 51 mm)	2 x 2 in	600 x 600	1200 x 1200	No pixel size for online renewal: JPG, JPEG, PNG, HEIC or HEIF, 54 KB to 10 MB (State Department)	US passport photo

UK passport (GOV.UK)	3.5 x 4.5 cm	1.38 x 1.77 in	413 x 531	827 x 1063	At least 600 x 750, 50 KB to 10 MB (GOV.UK)	UK passport photo
Indian passport (Passport Seva)	3.5 x 4.5 cm prints	1.38 x 1.77 in	413 x 531	827 x 1063	630 x 810 (Passport Seva guideline); each mission sets its KB limit, such as 250 KB at the Embassy of India in Bern	Indian passport photo
Canadian passport (Canada.ca)	5 x 7 cm (50 x 70 mm)	2 x 2 3/4 in	591 x 827	1181 x 1654	Online renewal: 1200 x 1800 to 3000 x 4500, 3:2 in portrait, JPEG, 200 KB to 5 MB	Canadian file check
Australian passport (Australian Passport Office)	3.5 to 4 cm wide, 4.5 to 5 cm high	1.38 to 1.57 in wide, 1.77 to 1.97 in high	413 to 472 wide, 531 to 591 high	827 to 945 wide, 1063 to 1181 high	None on the photo page	Not made here
Irish passport (Ireland.ie)	At least 3.5 x 4.5 cm, at most 3.8 x 5 cm	1.38 x 1.77 in to 1.50 x 1.97 in	413 x 531 to 449 x 591	827 x 1063 to 898 x 1181	At least 715 x 951, color JPEG, up to 9 MB, not a scan	Not made here
New Zealand passport (New Zealand Passports)	Not given	Not given	Not given	Not given	900 to 4500 wide and 1200 to 6000 high, 3:4 portrait, JPG or JPEG, 250 KB to 5 MB	Not made here
Singapore passport (ICA)	Not given	Not given	Not given	Not given	400 x 514 for ICA e-Services, JPG, JPEG, HEIC, HEIF or PNG, up to 8 MB	Not made here
Schengen visa (German missions in India, Czech MFA)	3.5 x 4.5 cm	1.38 x 1.77 in	413 x 531	827 x 1063	None on the consulate pages we read	Schengen visa photo
Chinese visa (Chinese consulate in Los Angeles)	3.3 x 4.8 cm (written 48mmx33mm)	1.30 x 1.89 in	390 x 567	780 x 1134	None on the consulate page	Passport photo maker
A form that only says passport size	3.5 x 4.5 cm	1.38 x 1.77 in	413 x 531	827 x 1063	The form’s own, if it gives one	35 x 45 mm photo
A form that asks for 2 x 2 inches	5.08 x 5.08 cm	2 x 2 in	600 x 600	1200 x 1200	The form’s own, if it gives one	2 x 2 inch photo

The 600 DPI column is worked out from millimeters, not by doubling the 300 DPI one: 413 x 531 doubled is 826 x 1062, but 35 x 45 mm at 600 DPI rounds to 827 x 1063.

Some rows come with conditions:

GOV.UK says that if you take the photo on your own device during the application, you should not crop it, because the service crops it for you.
Canada accepts only photos taken by a commercial photographer, for prints and for online renewal, so our Canadian page checks the studio’s file instead of making one.
The Australian Passport Office does not recommend online passport photo services or mobile apps and recommends a professional photo provider, so we have no Australian format.
We have no Irish, New Zealand or Singapore format. Our 35 x 45 mm file is 413 x 531 pixels, smaller than Ireland’s 715 x 951 minimum, and it has neither New Zealand’s 3:4 shape nor Singapore’s 400 x 514 pixels.

What “passport size” means in the US, India and the UK

In the US, “passport size” means the 2 x 2 inch square. In India and the UK it means 3.5 x 4.5 cm. For an Indian passport applied for in India, the photo is usually taken at the Passport Seva Kendra, so you seldom bring a print; the Indian passport photo page explains when you need one and covers the 630 x 810 upload from abroad, as well as the square photo that India’s visa and e-Visa forms ask for. A mission abroad may also set its own print size: the Embassy of India in Buenos Aires asks for 2 x 2 inch passport photos. None of the official Indian pages we read asks for 35 x 35 mm. If your embassy or consulate names a size, follow its page.

Head and face size by country

The frame is only half of the rule. Each office also sets how big the head must be inside it:

Document	Printed size	Head or face size	Background
US passport	2 x 2 in (51 x 51 mm)	Head 1 to 1 3/8 in (25 to 35 mm), chin to top of head	White or off-white
US visa	2 x 2 in, or a square file of 600 to 1200 px	File: head 50 to 69% of the image height, eyes 56 to 69% of the height up from the bottom. Print: head 1 to 1 3/8 in	White or off-white
UK passport	45 mm tall x 35 mm wide	Head 29 to 34 mm, chin to crown	Printed: plain cream or light gray. Digital: plain and light-colored
Canadian passport	50 x 70 mm	Face 31 to 36 mm, chin to crown; digital: 45 to 50% of the photo height	Plain white or light-colored
Schengen visa	35 x 45 mm (German missions in India, Czech consulates)	Face 70 to 80% of the photo; eyes to bottom of chin at least 13 mm (Czech consulates)	White (German missions in India)
Indian passport	630 x 810 px; 4.5 x 3.5 cm prints for Diplomatic and Official passport forms	Face 80 to 85% of the photo	White
Chinese visa	33 mm wide x 48 mm tall (the consulate writes 48mmx33mm)	Head 28 to 33 mm tall and 15 to 22 mm wide	White

India’s guideline is written to ICAO standards, and the ICAO photo guide that the European Commission publishes asks for a photo 35 to 40 mm wide with the face taking up 70 to 80% of it.

How to convert mm to pixels

The formula is pixels = millimeters ÷ 25.4 × DPI, rounded to the nearest whole pixel. It works because an inch is exactly 25.4 mm. Here is 35 x 45 mm at 300 DPI:

Turn millimeters into inches: 35 ÷ 25.4 = 1.378 in, and 45 ÷ 25.4 = 1.772 in.
Multiply by the DPI, using the unrounded inches: 35 ÷ 25.4 × 300 = 413.39, and 45 ÷ 25.4 × 300 = 531.496.
Round to whole pixels: 413 x 531 pixels.

The same photo at 200 DPI is 35 ÷ 25.4 × 200 = 275.6 and 45 ÷ 25.4 × 200 = 354.3, so 276 x 354 pixels. For sizes in inches, skip the first step: 2 inches × 300 DPI = 600 pixels, so a 2 x 2 inch photo is 600 x 600. The same math applies when the US State Department asks for a printed visa photo to be scanned at 300 pixels per inch: a 2 x 2 inch print then becomes a 600 x 600 file, the smallest size its visa form accepts.

To go the other way, use millimeters = pixels ÷ DPI × 25.4. A 630 x 810 pixel file printed at 300 DPI comes out at 53.3 x 68.6 mm, bigger than a passport photo. To print it at 35 x 45 mm, the file needs about 457 DPI.

Why 413 x 531, 276 x 354 and 354 x 472 come up

These numbers appear on forms and in search results without an explanation. Each one is a print size at a particular DPI:

Pixels	What it is	Shape
413 x 531	35 x 45 mm at 300 DPI	7:9
276 x 354	35 x 45 mm at 200 DPI	About 7:9 (rounding moves it slightly)
827 x 1063	35 x 45 mm at 600 DPI	7:9 to the nearest pixel
354 x 472	30 x 40 mm (3 x 4 cm) at 300 DPI	3:4
600 x 600	2 x 2 in at 300 DPI, and the smallest US visa file	1:1
630 x 810	India’s Passport Seva guideline	7:9

So 354 x 472 is not a 35 x 45 mm photo. It is a 3 x 4 cm photo, slightly narrower for its height. Squeezing a 35 x 45 mm photo into 354 x 472 pixels makes the face about 4% narrower. If your form asks for 35 x 45 mm, use 413 x 531 at 300 DPI. If it really asks for 354 x 472, crop to that shape rather than stretching.

The 35:45 ratio, and why shape matters

35:45 simplifies to 7:9, so a 35 x 45 mm photo is about 0.78 times as wide as it is tall. 413 x 531 is exactly 7:9 (59 × 7 and 59 × 9), and so are 630 x 810 and 700 x 900. Any file with that shape prints at 35 x 45 mm once its DPI is set right, and more pixels only make a sharper print.

Other formats have their own shapes. The US photo is square (1:1). The UK online minimum of 600 x 750 is 4:5. Canada’s print is 5:7, while its digital file is what Canada calls 3:2 taken in portrait mode, 2 wide for every 3 tall. New Zealand asks for 3:4. Resizing a photo from one shape to another without cropping stretches the face, which is why passport tools crop first and resize second.

Does DPI matter for an online upload?

No. The upload rules in the size table at the top of the page set pixels, a file size or both, and none of them asks for a DPI value in the file. The DPI value stored in a file is only a note about how large each pixel should come out, which the PNG standard calls the intended pixel size. Changing it does not change a single pixel, so a 630 x 810 file is still 630 x 810 at 72, 300 or 600 DPI.

DPI does matter when you print. A 413 x 531 file marked 300 DPI prints at 35 x 45 mm, and the same file marked 200 DPI prints at about 52 x 67 mm. If your file has the right pixels but the wrong DPI, change image DPI sets a new value without touching the pixels. If a form gives the size in centimeters with a KB limit, resize in cm and KB sets both at once.

Head size in pixels

The head rules above convert to pixels the same way. These are the ranges inside a photo at the stated size, rounded inward so both ends stay inside the official range:

Format	Photo in pixels	Head in pixels
US passport, 2 x 2 in at 300 DPI	600 x 600	About 300 to 412 (1 to 1 3/8 in)
US visa file	600 x 600	Head 300 to 414; eyes 336 to 414 up from the bottom
US visa file	1200 x 1200	Head 600 to 828; eyes 672 to 828 up from the bottom
UK passport, 35 x 45 mm at 300 DPI	413 x 531	About 343 to 401 (29 to 34 mm)
Canadian passport print, 50 x 70 mm at 300 DPI	591 x 827	About 367 to 425 (31 to 36 mm)
Canadian online renewal file	1200 x 1800	810 to 900 (45 to 50% of the height)
Chinese visa, 33 x 48 mm at 300 DPI	390 x 567	About 331 to 389 (28 to 33 mm)

The Indian and ICAO percentages say how much of the photo the face should take up, but not whether that means height or area. Our tools read them as height, so in a 630 x 810 Indian passport photo the face from chin to the top of the hair is 648 to 688 pixels tall (80 to 85% of 810).

How to make a passport photo at the right pixel size

Find the rule for your form. If it names pixels and KB, as most online forms do, use those. If it names only a print size, you need that size at 300 DPI.
Open the matching format. The passport photo maker has every format linked in the size table at the top of the page; for Canada it checks the studio’s file instead of making a photo. There are also direct pages for 35 x 45 mm, 2 x 2 inch, Indian, US and UK passport photos, and for US visa and Schengen visa photos.
Choose Line it up for me, then tap the top of the head and the chin. The tool crops to the exact shape, sizes the head inside the range for that format and centers it.
Download the file or a print sheet. The 35 x 45 mm file is 413 x 531 pixels with 300 DPI stored in it, the Indian one exactly 630 x 810, and the US visa one 600 x 600. For prints, a 4 x 6 inch sheet holds eight 35 x 45 mm photos or two 2 x 2 inch photos, and an A4 sheet holds 30 or 15.
Check the file size. If the form sets a KB limit and the file is over it, compress to a size in KB with Exact size set to your pixel size, so the pixels stay the same.

Do not retouch or filter the photo: India’s guideline asks for photos unaltered by computer software. That is why, for official formats, the tool does nothing beyond cropping and resizing. It all runs in your browser, so the photo stays on your device.

Questions

What is the passport size photo size in pixels?

For the common 35 x 45 mm photo, 413 x 531 pixels at 300 DPI, or 276 x 354 pixels at 200 DPI. A US 2 x 2 inch photo is 600 x 600 pixels at 300 DPI. When a form names its own pixel size, use that instead: India's Passport Seva guideline asks for 630 x 810 pixels.

What is 35 x 45 mm in pixels? Is 45 x 35 mm different?

35 x 45 mm is 413 x 531 pixels at 300 DPI, 276 x 354 at 200 DPI and 827 x 1063 at 600 DPI, always width first. 45 x 35 mm is the same photo written height first, the way GOV.UK writes it: 45 mm tall and 35 mm wide. The 35 x 45 mm photo maker saves a 413 x 531 pixel file.

What is the size of a 2x2 photo in width and height?

2 inches wide and 2 inches tall, which is 5.08 x 5.08 cm (the US State Department writes 51 x 51 mm). In pixels that is 600 x 600 at 300 DPI, 400 x 400 at 200 DPI and 1200 x 1200 at 600 DPI. Make one with the 2 x 2 inch photo maker.

What is the passport size photo size in cm and inches?

3.5 x 4.5 cm, or 1.38 x 1.77 inches (about 1 3/8 x 1 3/4), in India, the UK and the Schengen area. A US passport photo is 5.1 x 5.1 cm (2 x 2 inches), a Canadian one 5 x 7 cm (2 x 2 3/4 inches) and a Chinese visa photo 3.3 x 4.8 cm (1.30 x 1.89 inches). Ireland accepts 3.5 x 4.5 cm up to 3.8 x 5 cm, and Australia 3.5 to 4 cm wide by 4.5 to 5 cm high.

Is 354 x 472 pixels a passport size photo?

Not a 35 x 45 mm one. 354 x 472 pixels is a 30 x 40 mm (3 x 4 cm) photo at 300 DPI, a slightly different shape. For 35 x 45 mm at 300 DPI you need 413 x 531 pixels. Use 354 x 472 only when your form asks for exactly that, and crop to it rather than stretching the photo.

What is the 35:45 ratio?

35:45 simplifies to 7:9, so the width is about 0.78 of the height. 413 x 531, 630 x 810 and 700 x 900 pixels all have that exact shape, so any of them prints at 35 x 45 mm at the right DPI.

What DPI should a passport photo be?

For an upload, DPI does not matter: the official upload rules we checked set pixels or a file size, never a DPI. For a print, the DPI decides how large the pixels come out. At 300 DPI, 413 x 531 pixels prints at 35 x 45 mm, and the US State Department asks for a printed visa photo to be scanned at 300 pixels per inch. You can change the DPI stored in a file without touching the pixels.

Can I just resize my photo to these pixel sizes?

Only if it already has the right shape and the head is the right size. Resizing a phone photo straight to 413 x 531 or 630 x 810 squashes or stretches it. Crop it first: the passport photo maker crops to the exact shape and sizes the head for the format you pick. Enlarging a small photo to reach a size such as 600 x 600 or 630 x 810 spreads the same detail over more pixels, so it does not get sharper, and the US State Department asks for a high-resolution photo that is not blurry, grainy or pixelated. If your photo is too small, take a new one.
