18×18 inches at 300 DPI is 5400×5400 pixels. The arithmetic is inches × DPI, so 18 × 300 = 5400 and 18 × 300 = 5400.
| Resolution | Pixel dimensions | Good for |
|---|---|---|
| 300 DPI | 5400 × 5400 px | Print. The standard buyers expect. |
| 200 DPI | 3600 × 3600 px | Acceptable at arm's length; visibly softer up close. |
| 150 DPI | 2700 × 2700 px | Too low for a print you are charging for. |
| 72 DPI | 1296 × 1296 px | Screen only. Never sell this as a printable. |
The ratio matters more than the size
18×18 is a 1:1 ratio. Every other print size that reduces to 1:1 can be cut from the same master file without redrawing anything — which is why sellers who work in ratios list far more sizes for the same effort than sellers who work in inches.
Before you list it
- Export at 5400×5400 px and confirm the file actually reports 300 DPI, not 72.
- Check the true pixel dimensions rather than trusting the DPI field — software often lies about it.
- If your source image is smaller than 5400×5400, upscaling will show. Rebuild or offer a smaller size.
