Platform spec
Printify image requirements
Dimensions are decided by the product and the print provider, so there is no single Printify size — anyone quoting one is quoting a different platform. Prepare at 300 DPI across whatever print area the chosen provider uses. Files are capped at 100 MB for PNG and JPG, 20 MB for SVG.
Full specification
| 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 |
Why the recommended size matters more than the DPI figure
DPI is a ratio, and a ratio without a physical size tells you nothing. Rather than remembering "it needs 300 DPI", remember this platform's recommended pixel dimensions — get the pixel count right and the DPI follows. The reverse never works: a file tagged 300 DPI with too few pixels fails everywhere.
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.
Frequently asked questions
What size should an image be for Printify?
There is no single answer, and anyone giving you one is quoting a single product page. Printify sets dimensions per product and per print provider. Check the requirement on the specific product, or build one master at 4500 × 5400 and scale down.
What is the maximum file size on Printify?
100 MB, or 20 MB for SVG. Going over it is one of the few things that reliably stops an upload.
Can I upload a WebP to Printify?
No. Printify accepts JPEG, PNG, SVG. WebP is not on the list at any of the four platforms, and several design tools now export it by default — so this catches people who got everything else right. Re-export as PNG.
Is 300 DPI enough for Printify?
DPI on its own is not a quantity — it only means something once you fix a physical size. Printify advises 300 DPI, measured across the 15″ × 18″ print area, which works out to 4500 × 5400 pixels. A file tagged 300 DPI with fewer pixels than that is not 300 DPI where it counts.
Will Printify reject a low-resolution file?
No. Printify publishes no density at which an upload is refused; low resolution produces a warning at most. That is the trap — the file goes through, the product lists, and the problem surfaces when a customer opens the parcel.
Does Printify need a transparent background?
Yes. Without an alpha channel the white background is treated as ink, and on a dark garment it prints as a visible white box around the artwork.
How current are these numbers?
