How to use it
- Click Choose a file and pick a photo of one person, or drop it on the box. Take a recent photo, facing the camera.
- Choose the Document. The frame changes to its size. Drag the picture to move it, and use Zoom until the head fills the size the rule asks for.
- Move the Crown line to the top of the head and the Chin line to the bottom of the chin. For the UK and ICAO documents the line is green when the head is inside the range.
- Click Download the photo for one photo, or Download a 10 × 15 cm sheet of copies for a print, and print it on photo paper.
The sizes and head rules of each document
The UK profile follows GOV.UK, "Get a passport photo: Printed photos". It says the photo must measure 45 millimetres high by 35 mm wide, and that the head, from the crown to the chin, must be between 29 mm and 34 mm high. The guidance also asks for a photo taken within the last month, printed on plain white photographic paper with no border, and unaltered by computer software.
The ICAO profile follows ICAO Doc 9303 Part 3, section 3.9.1.2. It says that submitted portraits should be 45.0 mm x 35.0 mm, and that the crown-to-chin length of the face shall be 70 to 80 per cent of the longest dimension of the portrait area. This tool takes the frame's height as that dimension. ICAO also asks for a portrait captured within the last six months, and for no more than three months before it should be accepted.
The Turkish profile follows two notes of the Turkish consulates general. The New York note, "Biyometrik Fotoğraf Özellikleri" for passport and identity card applications, says the photo must be 50 mm x 60 mm, show the whole face, have a plain white background and be no older than six months. The Berlin note (information note 413738, dated 27 January 2026 in its header) gives the same 50 mm x 60 mm, a plain white background and a photo taken within the last six months. Neither note gives a head size, so the Turkish profile shows the head but gives no verdict. The national office pages could not be read when these figures were checked, so confirm the details with the office before you apply.
How the frame and the head are measured
Each frame is written at 300 pixels per inch. The UK and ICAO frames of 35 mm by 45 mm are 413 by 531 pixels; the Turkish frame of 50 mm by 60 mm is 591 by 709 pixels. ICAO asks for printed photos that scan at 300 pixels per inch, so the page writes every photo at that resolution. The download is a JPEG at 95 per cent quality.
The head is measured between the two guide lines, not found by face detection. The distance between the lines, in pixels, is divided by the frame's height in pixels and multiplied by the frame's height in millimetres. For ICAO the same distance is shown as a share of the frame's height. The page checks the reading against the range of the UK and ICAO profiles and colours the lines green or red; for the Turkish profile the lines are blue, because there is no range to check.
The sheet is 10 by 15 cm at 300 pixels per inch, 1181 by 1772 pixels. The UK and ICAO sheets hold six copies of the 35 by 45 mm photo, two across and three down. The UK and ICAO copies are separated by a gap of 2 mm for cutting apart. The Turkish sheet holds four copies of the 50 by 60 mm photo, two across and two down, which makes 100 by 120 mm with 15 mm of white above and below. The copies touch with no margin at the sides, because 10 by 15 cm photo paper is printed borderless, and thin light-grey cut lines run between them.
Example: a UK printed photo
The frame is 413 by 531 pixels. With the default lines, the crown line is at 74 pixels and the chin line at 446 pixels, so the head is 372 pixels long. 372 divided by 531 is 0.7006, and 0.7006 times 45 mm is 31.5 mm. That is inside the UK range of 29 to 34 mm, so both lines turn green.
The UK download is 413 by 531 pixels. The sheet is 1181 by 1772 pixels with six copies, two across and three down.
Frequently asked questions
Is my photo uploaded when I use this tool?
No. Your browser reads the photo, places it in the frame and writes the new JPEG on your device. You can check this by turning off your internet connection after the page has loaded and making a photo.
Which size does the UK profile use?
The GOV.UK printed photo rule: 45 mm high by 35 mm wide, with the head from the crown to the chin between 29 and 34 mm. The UK profile uses that frame and that head range.
Does this tool check my photo against the official rules?
It measures only what you place: the frame, the zoom and the two guide lines. It does not detect the face, the lighting, the expression or glasses, so you still have to check those against the rule yourself.
Can I use this photo for a Turkish passport or identity card?
The frame is 50 mm by 60 mm, the size both Turkish consulate notes give. Those notes give no head size, so the head is not judged here. Confirm the details with the issuing office before you apply, because the national office pages could not be read when this was checked.
Can I use this photo for a US passport?
Not from this tool. The US embassy pages that state the 2 by 2 inch rule could not be opened, so the tool has no US profile. Check the size and head rule with the State Department or the embassy before you apply.
Why is the Turkish photo 591 by 709 pixels?
A photo of 50 mm by 60 mm at 300 pixels per inch is 591 by 709 pixels. It is written at the same resolution as the UK and ICAO photos, which ICAO Doc 9303 uses for printed photos scanned at 300 pixels per inch.
