45×60mm Photo — Pixels, Ratio and Print Layout

How Many Pixels Is a 45×60 mm Photo? (2026)

A 45 × 60 mm photo is 531 × 709 pixels at 300 DPI print resolution. The calculation is a single line: 45 ÷ 25.4 × 300 = 531.50 and 60 ÷ 25.4 × 300 = 708.66, which rounds to 531 × 709 at the nearest whole pixel. The same size becomes 1063 × 1417 pixels at 600 DPI.

Because of the fractions you will also see 531 × 708 pixels in some tools: one rounds the decimal up, another truncates it. The difference between the two is 0.08 millimetres, and no institution measures that, because acceptance is judged on the physical size rather than the pixel count. If you want to compare formats, the full table of document photo sizes sits on a single page.

Are 45 × 60 mm and 50 × 60 mm the Same Thing?

No. The two sizes share the same height (709 pixels at 300 DPI) but differ by five millimetres in width, and that moves the ratio from 3 : 4 to 5 : 6. The gap looks small yet changes the outcome: NVİ requires the biometric photo for a Turkish ID card application to be 50 mm × 60 mm on a plain white background, and states plainly that a photo in a different size may leave the application incomplete, or — even if the application goes through — may fail quality control during card production and be cancelled.

The reverse direction behaves the same way: shrinking a 50 × 60 file does not turn it into 45 × 60, because scaling preserves the ratio. The correct operation is a fresh crop, taking margin off the sides so the head position settles again. The full rule set for the biometric side lives on the 50 × 60 mm size page; this page only answers the size, pixel and print question for 45 × 60.

How Many 45 × 60 Photos Fit on a 10 × 15 Sheet?

Four, at true size. A “10 × 15” photo sheet is actually 4 × 6 inches, that is 101.6 × 152.4 mm, which equals 1200 × 1800 pixels at 300 DPI. Two columns of 45 mm take 90 mm and two rows of 60 mm take 120 mm; the remaining margin is distributed to the edges as cutting tolerance. The smaller 35 × 45 mm format fits eight times on the same sheet — the larger the photo, the fewer copies per sheet.

One detail makes 45 × 60 easier in practice: its ratio is 3 : 4, and most phone cameras natively shoot 4 : 3. A frame taken with the phone held upright therefore maps onto the 45 × 60 crop without distortion, whereas 50 × 60 and 35 × 45 always require margin to be taken off somewhere. Shooting vertically from the start rather than rotating a landscape frame also avoids losing resolution.

Which Values Apply When Uploading a 45 × 60 Photo?

Millimetres mean nothing in a digital upload; the system looks at pixel dimensions, file format and the kilobyte limit. Saying “I uploaded 45 × 60 mm” is therefore not enough: the file has to be 531 × 709 pixels, saved in the format the form accepts (usually JPEG) and, where one exists, inside the size range. PNG is lossless and preferred for printing; on forms with a size cap, JPEG at 90% quality or above is the safe band.

The clearest example that one person may need two different files — one for print, one for upload — is e-Okul: the Turkish Ministry of Education e-Okul guide requires the student photo added to the system to be 133 × 171 pixels (the 35 × 45 mm equivalent) in JPEG format, at least 20 and at most 150 kilobytes, and no older than six months. So the print a student hands to the file may be 45 × 60 mm while the digital image entering the system is a completely different pixel value; the process details are on the student ID and enrolment photo page.

Which Institutions Ask for a 45 × 60 mm Photo?

4.5 × 6 cm is the classic size of institutional files in Turkey, and official guides name it as such: in the university enrolment section of the ÖSYM YKS guide, the list of documents required for registration includes the item “12 photographs of 4.5 cm x 6 cm, if requested by the higher education institution”. Both halves of that sentence matter: the size is 4.5 × 6 cm, and whether it is requested at all is left to the institution.

In practice course and certificate programme registrations, association and club membership files, institutional archive files and job application files ask for the same size. Biometric documents sit outside it, however; you can check which size applies to which document on the Turkish biometric photo sizes by document page. The number of copies and the background colour always depend on the institution’s own notice — reading the form or the announcement is safer than assuming a number you saw on a page.
