Pixels, DPI and print size
Pixels to print size calculator for POD artwork.
Convert pixel width and height into inches and centimeters at 300 DPI — or any custom resolution — and compare common print-on-demand canvas sizes before export.
Artwork dimensions
Enter the actual pixel size of the file and the DPI you want to evaluate.
Physical print size at 300 DPI
Formula: pixels ÷ DPI = inches. This is a mathematical conversion, not a guarantee that a print provider will accept the file or that the artwork will look sharp.
Quick reference
Common pixel dimensions and print sizes at 300 DPI
At 300 DPI, divide each pixel dimension by 300 to get inches. These values are mathematical references for popular POD canvas shapes; always compare the result with your provider's current template.
| Pixels | Inches at 300 DPI | Centimeters | Typical use |
|---|---|---|---|
| 4500 × 5400 px | 15 × 18 in | 38.10 × 45.72 cm | Large T-shirt artwork |
| 4500 × 5100 px | 15 × 17 in | 38.10 × 43.18 cm | Apparel print area |
| 4000 × 5000 px | 13.33 × 16.67 in | 33.87 × 42.33 cm | Portrait merchandise |
| 3600 × 4800 px | 12 × 16 in | 30.48 × 40.64 cm | T-shirts and posters |
| 3000 × 3000 px | 10 × 10 in | 25.40 × 25.40 cm | Square artwork |

Why it helps
Check the production details before they become listing problems.
Shows the exact mathematical relationship between pixel dimensions, DPI and physical print size.
Lets you compare the same artwork at different DPI values without resizing or uploading the file.
Includes common large-canvas presets as quick starting points, while keeping every value editable.
Reports megapixels so you can quickly understand the overall amount of image data in the canvas.
Simple workflow
How to use this free tool
- 1

- 2
Use 300 DPI as a common high-resolution reference, or enter the resolution required by your production workflow.
- 3
Compare the calculated physical size with your product template, then resize or regenerate if necessary.

Useful answers
Frequently asked questions
Is 300 DPI always required for POD?
No single DPI rule covers every product and provider. 300 DPI is a useful reference for many print workflows, but always follow the current template and requirements of the provider you use.
Does changing the DPI field resize my artwork?
No. The calculator only shows how the existing pixel dimensions translate into physical size. It never modifies or uploads a file.
Why can a large file still print poorly?
Pixel count is only one factor. Compression, upscaling, blurry source material, thin lines and low contrast can all reduce print quality even when the dimensions are large.
