How to use this tool?
1. Check Max Size
Enter your image's pixel dimensions (e.g. 4032 x 3024). The tool calculates how large you can print it without it looking blurry.
2. Reverse Calculation
Switch to "Print Size → Pixels" mode. Select a target paper size (like A3), and we'll tell you the minimum resolution you need.
3. Viewing Distance
Use the value slider. A billboard seen from 3 meters away needs much less detail (PPI) than a magazine held in your hands.
