Why DPI matters
"DPI" (dots per inch) is a measure of how much detail an image can reproduce at a printed size. A shirt graphic that's 1000 px wide will print crisply at 3 inches wide (≈333 DPI) but softly at 10 inches (≈100 DPI). The print standard is 300 DPI at final size. Below 200 DPI, detail breaks down visibly.
This tool computes the effective DPI given your image's pixel dimensions and the physical target size. It checks aspect ratio against the chosen preset and flags obvious issues like extreme file sizes or mismatched proportions.
FAQ
What DPI do I need for CD printing?
300 DPI at the final print size. For a 120 × 120 mm CD front cover, that means at least 1417 × 1417 px.
What about DTG t-shirt prints?
300 DPI at the final print area (usually 300 × 400 mm front). So ~3500 × 4700 px is ideal. 200 DPI still works for photographic art.
Is RGB or CMYK required?
We accept both. For Pantone-accurate spot printing, send artwork already in the correct color mode. For CD/DTG, RGB is fine — we convert automatically.
Does this tool upload my file anywhere?
No. All analysis runs locally in your browser — the file never leaves your device.
