Preparing your files for great prints
Resolution, color space, brightness and file format — 5 things to check for sharp, accurate prints.
October 3, 20261. Enough pixels for the print size
Quick formula: pixels needed = size (cm) ÷ 2.54 × dpi.
| Size | Great (300 dpi) | Acceptable (150 dpi) |
|---|---|---|
| 10×15 cm | 1200×1800 | 600×900 |
| 20×30 cm | 2400×3500 | 1200×1800 |
| 40×60 cm | 4700×7100 | 2400×3500 |
Wall art is viewed from a distance, so 150 dpi is fine; hand-held prints should be close to 300 dpi.
2. Send originals, not compressed copies
Photos sent through chat apps and social networks are heavily compressed. Download the original file from your camera, Google Photos ("Download" original) or iCloud.
3. sRGB color space
Most photo printers work best with sRGB. If you edit in Lightroom / Photoshop, export as sRGB. [To be confirmed: does the lab accept Adobe RGB / CMYK files?]
4. Brighten slightly
Screens emit light, so photos look brighter than on paper. A photo that's a bit dark on screen prints even darker — raising exposure by about +0.3 to +0.5 usually works well.
5. File format
High-quality JPG (90–100%) is enough for most prints. The website accepts JPG, PNG and WebP up to 200 MB per photo.
