How to find out how big you can print a photo
- Add the photo: its width and height in pixels are read automatically. Or type the pixel size if you only know it.
- Read the table: for each print size you see the resulting DPI, a quality rating and how much of the picture would be cropped to fill the paper.
- Click “Prepare” next to the size you want to save a print-ready copy: cropped to that shape (or with white borders) and set to the right DPI.
Quality ratings
| DPI on paper | Rating | What it looks like |
|---|---|---|
| 300 and above | Excellent | Sharp even when held close |
| 240–299 | Very good | Indistinguishable from 300 for most photos |
| 180–239 | Good | Fine for frames on a wall |
| 120–179 | Fair | OK from a distance (posters, canvases) |
| Below 120 | Poor | Visibly soft or pixelated |
Typical camera and phone photos
| Camera | Pixels | Sharp print (300 DPI) | Good print (200 DPI) |
|---|---|---|---|
| 12 MP phone | 4032 × 3024 | 13.4 × 10.1 in | 20.2 × 15.1 in |
| 24 MP camera | 6000 × 4000 | 20 × 13.3 in | 30 × 20 in |
| WhatsApp photo | 1600 × 1200 | 5.3 × 4 in | 8 × 6 in |
Why some sizes crop the photo
Print sizes have different shapes: 4 × 6 is 3:2 (like most cameras), 8 × 10 and 16 × 20 are 5:4, A4 and A3 are about 1.41:1, and phone photos are 4:3. To fill the paper, part of the photo must be cut off. The table shows how much; untick “crop” to keep the whole photo with white borders.
Frequently asked questions
How big can I print a photo?
Divide the pixels by the print resolution: at 300 DPI (the standard for sharp prints) a 3000 × 2000 px photo prints at 10 × 6.7 in. At 200 DPI it can go to 15 × 10 in and still look good; posters viewed from a distance can go lower.
What DPI do I need for printing?
300 DPI for small prints you hold in your hand (4 × 6, 5 × 7), 200–240 DPI is fine for 8 × 10 to A3, and 150 DPI or less is acceptable for posters seen from a metre or more away.
Why does my photo get cropped at some sizes?
Phone photos are usually 4:3 and camera photos 3:2, while prints such as 8 × 10 are 5:4. To fill the paper, part of the photo has to be cut off. The table shows how much; untick “crop” to keep the whole photo with white borders instead.
What does “Prepare” do?
It crops the photo to the shape of the print you picked (from the centre) and saves a high-quality JPG with the DPI set so the file prints at exactly that size.
Are my photos uploaded?
No. Everything happens in your browser, so your photos never leave your device.
