I wrote this page because people keep landing on this site with the same question: "10x15 in pixel". A print shop or a photo machine asks for a 10x15 photo, your phone talks in pixels, and nobody tells you how the two fit together. Here are the numbers, a small calculator, and a quick way to check if your photo is good enough before you pay for the print.
Tap a size or type your own. Everything runs on your phone. Nothing is uploaded.
DPI means dots per inch: how many pixels go into one inch of paper. More DPI, sharper print. For photos, 300 is the normal choice. Below 150 most people start to see soft edges.
| DPI | Pixels (portrait) | Good for |
|---|---|---|
| 72 | 283 x 425 | Screen only, too small to print |
| 96 | 378 x 567 | Screen only |
| 150 | 591 x 886 | Okay print, looks fine from arm's length |
| 200 | 787 x 1181 | Good print |
| 300 | 1181 x 1772 | Best — what print shops expect |
| 600 | 2362 x 3543 | Not needed for a 10x15, the file only gets heavier |
Pick a photo from your phone. The page only reads its size, the picture never leaves your device. Or type the pixel size yourself.
The check assumes a 10 x 15 cm print. It looks at pixels only — it cannot see if the photo is blurry, dark or shaky.
A 10x15 print has the shape 2 : 3. Most phone photos are 3 : 4, a little wider and shorter. So when you print one as 10x15, the machine has to cut a strip off the top and bottom (or the sides). Heads and feet are often the first things to go.
The fix is simple: crop the photo to 2 : 3 yourself before you print, so you decide what gets cut, not the machine. Our Crop Image tool does that in the browser.
One more small thing. Some shops print exactly 10 x 15 cm, others print 4 x 6 inch, which is 10.2 x 15.2 cm. The difference is about 2 mm, so either file works. Just keep text and faces a little away from the edge.
For a 10x15 that you hold in your hand, 300 DPI is the target and 200 is still nice. A normal phone camera today makes photos of 3000 pixels or more on the short side, which is far more than 1181. So with a fresh phone photo you are almost always fine.
Where it goes wrong is with photos that were sent over chat apps. Many apps shrink photos to save data, sometimes down to around 1000–1600 pixels. That can still print okay, but it is worth checking above before you pay.
What is 10x15 cm in pixels?
1181 x 1772 pixels at 300 DPI. At 200 DPI it is 787 x 1181, and at 150 DPI 591 x 886.
Is 10x15 cm the same as 4x6 inch?
Almost. 4 x 6 inch is 10.16 x 15.24 cm, so it is 1200 x 1800 pixels at 300 DPI. Shops treat the two as the same size.
Can I print a 1080 x 1920 photo as 10x15?
Yes. On the short side that gives about 274 DPI, which looks good. The shape is different though (9 : 16), so a lot will be cut off. Crop it to 2 : 3 first.
Does a bigger file mean a better print?
No. What matters is the number of pixels, not the KB or MB. A well-compressed photo with enough pixels prints just as well.
Written 7 October 2026. The numbers on this page are maths, not opinion: inches × DPI = pixels, and one inch is 2.54 cm.
