Printful requires 300 DPI at print size. For standard t-shirt front prints, that's 4500x5400 pixels. Each product has different requirements — check Printful's guidelines for specific products.
Why does Printful say my image quality is low?
Printful warns when your image is below 300 DPI at the product's print size. Use this resizer to scale up your design, then apply the Sharpen tool to improve clarity.
