Print guide
Standard photo print sizes: inches, millimetres and pixels
A quick reference for the sizes asked for most often at Indian photo and frame counters. Photo sizes are usually spoken of in inches; paper sizes like A4 are metric.
| Size | mm | Shape (W:H) | Pixels at 300 PPI |
|---|---|---|---|
| 4 × 6 in | 102 × 152 | 2:3 | 1200 × 1800 |
| 5 × 7 in | 127 × 178 | 5:7 | 1500 × 2100 |
| 6 × 8 in | 152 × 203 | 3:4 | 1800 × 2400 |
| 8 × 10 in | 203 × 254 | 4:5 | 2400 × 3000 |
| 8 × 12 in | 203 × 305 | 2:3 | 2400 × 3600 |
| 10 × 12 in | 254 × 305 | 5:6 | 3000 × 3600 |
| 12 × 18 in | 305 × 457 | 2:3 | 3600 × 5400 |
| A4 | 210 × 297 | ≈ 1:1.41 | 2480 × 3508 |
| A3 | 297 × 420 | ≈ 1:1.41 | 3508 × 4961 |
Pixels are shown portrait (width × height); turn them round for landscape. At 200 PPI you need two-thirds of these numbers.
How to read the table
- Same shape, different size: 4×6, 8×12 and 12×18 are all 2:3, the shape of many camera photos. A photo can usually go between them without new cropping.
- 8×10 is squarer. Expect a crop when an ordinary photo goes into it — see fit vs fill.
- Missing a size? Multiply each side in inches by 300 for the pixels, or use the calculator, which accepts any custom size in inches or millimetres.
Frame size vs print size
"An 8×10 frame" can mean the size of the photo it holds or the outside size of the frame, and a mount (mat) makes the visible window smaller than the print. Frame and mount sizes vary between suppliers, so measure the opening of the frames you actually stock and record that as the print size.
Mugs, T-shirts and other gift products have no standard print area — it depends on the blank and the printing method. Use your supplier's template or measure a sample.
