How to read this
- If the aspect ratio is wrong, the platform crops it. Matching the ratio matters more than matching the pixel count.
- Print assumes 300 dpi: divide the pixels by 300 for inches, then multiply by 25.4 for millimetres.
- On screen, dpi is irrelevant — only the pixel size counts. Dpi only means something when you print.
- Enlarging a small image makes it blurry. Start bigger than you need and scale down instead.
