Credit tiers: up to 4.2 MP = 1 credit; up to 16.8 MP = 3 credits.
Required pixels = print size in inches × PPI. For wall prints viewed from a distance, 150–200 PPI usually looks good; 300 PPI suits close-up photo prints.
| Print size | 150 PPI | 200 PPI | 300 PPI |
|---|---|---|---|
| 8 × 10 in | 1,200 × 1,500 | 1,600 × 2,000 | 2,400 × 3,000 |
| 12 × 18 in | 1,800 × 2,700 | 2,400 × 3,600 | 3,600 × 5,400 |
| 18 × 24 in | 2,700 × 3,600 | 3,600 × 4,800 | 5,400 × 7,200 |
If the aspect ratio of your image differs from the print (for example a square image on an 18 × 24 in poster), upscaling alone will not fix it — you will need to crop or add borders.
