Checker
Printify size checker
All four of Printify's hard numbers, checked at once. The file stays in your browser.
Batch, auto-fix and exports
Everything above is free for one file at a time, and always will be. Doing it to a whole folder — batch checking up to 100 files, one zip with every platform file for every design, and a CSV report — is part of Seller.
Exports are padded and centred to each platform's size on a transparent canvas. Nothing is ever upscaled — a file enlarged to pass a dimension check still prints soft, which is the failure this tool exists to prevent.
Printify: the numbers that matter
| Dimensions | product → print provider → print area |
|---|---|
| Recommended density | 300 DPI |
| Large-format products | 120 – 150 DPI (leggings, blankets, tapestries) |
| Maximum PNG / JPEG | 100 MB |
| Maximum SVG | 20 MB |
| Authoritative source | the design template for the chosen product |
How this tool calculates DPI
It ignores the DPI tag written into the file and divides the pixel count by the 15″ × 18″ print area instead — which is the figure the platform actually enforces.
Frequently asked questions
What DPI does Printify require?
Prepare at 300 DPI across the print area. Printify is permissive about low-resolution uploads, so the risk sits in the finished product rather than at the upload step.
Do I need an account to check a file?
No. The whole check runs in your browser — no account, no upload.
