Pixels = size in inches × DPI. Check your own image against the number before sending it to print.
How to calculate print size
Pixels = size in inches × DPI. The calculator handles any custom size.
| At 150 DPI | At 300 DPI | |
|---|---|---|
| A4 · 21 × 29.7 cm | 1,240 × 1,754 | 2,480 × 3,508 |
| A3 · 29.7 × 42 cm | 1,754 × 2,480 | 3,508 × 4,961 |
| Poster · 50 × 70 cm | 2,953 × 4,134 | 5,906 × 8,268 |
| Photo · 8 × 10 in | 1,200 × 1,500 | 2,400 × 3,000 |
| Tablecloth · 140 × 80 cm | 8,268 × 4,724 | 16,535 × 9,449 |
Multiply each side in inches by the DPI. A 60 × 90 cm print at 300 DPI needs 7,087 × 10,630 pixels. This calculator does the math for any size.
Divide the pixels by the DPI to get inches, then multiply by 2.54. 3,000 px at 300 DPI prints 25.4 cm wide. The Pixels ↔ Inches converter does this at any DPI.
300 DPI for anything viewed in the hand — cards, photo prints, fabric repeats. 150 DPI is fine for posters, banners and wallpaper seen from a distance.
DPI alone means nothing — it only becomes pixels when paired with a physical size. 300 DPI at A4 is 2,480 × 3,508 px; at 50 × 70 cm it is 5,906 × 8,268 px.
Either print smaller, accept a lower DPI, or add real pixels with AI Upscale — it sharpens to 2K, 4K or 8K without changing the picture.
