About the 3 × 4 cm photo maker tool
A 3 × 4 cm photo is 30 mm wide and 40 mm high: an upright rectangle in the classic 3:4 shape. It is asked for on many national ID cards, residence permits, student and work cards and forms in several countries. At 300 DPI it is 354 × 472 pixels, which is the file this page makes.
No single official rule covers 3 × 4 cm photos, so this page uses a guideline taken from passport photos: under ICAO's guidance, as published by Taiwan's Bureau of Consular Affairs, the head from the chin to the crown fills 70 to 80% of the photo height. On a 40 mm photo that is 28 to 32 mm. If your form gives its own head size or shows an example, adjust the crop with the zoom and drag until it matches before you create the photo.
Don't confuse 3 × 4 cm with 35 × 45 mm: the passport size is 5 mm wider and taller and a slightly different shape, and an office that asks for one won't take the other. There is a separate page for 35 × 45 mm photos, and the document list above the upload box has passport and visa photos with their own rules.
The maker replaces the background with plain white by default. Light grey and off-white are there for forms that want a light background, and light blue for the forms that ask for blue. Only the background is replaced; your face is not edited.
To print, choose a layout under the finished photo: a 4 × 6 inch print, a 5 × 7 inch print or an A4 page. The tool shows how many 3 × 4 photos fit on each and adds cut marks. Print at 100% or “actual size”, never “fit to page”, and measure one photo with a ruler: it should be 30 mm wide.
Frequently asked questions
How many pixels is a 3×4 cm photo?
354 × 472 pixels at 300 DPI. Printed at 100% (actual size), the photo measures 30 × 40 mm.
Is a 3×4 photo the same as a 35×45 photo?
No. A 3 × 4 cm photo is 30 × 40 mm, smaller than 35 × 45 mm and a slightly different shape. Use the size your form asks for; for 35 × 45 mm there is a separate page.
Does 3×4 mean centimeters or inches?
Almost always centimeters (30 × 40 mm) for ID photos. A 3 × 4 inch photo would be far too large for a document; check your form if it doesn't say.
