Image DPI Checker
Check if your artwork is high-resolution enough to print sharp.
| If you print at… | Largest sharp size |
|---|---|
| 300 DPI — standard, viewed up close | — |
| 150 DPI — large art, viewed from afar | — |
How to check your image’s DPI
- Upload your artwork. It stays on your device — nothing is sent anywhere.
- Enter the size you want to print in inches or centimetres.
- Read the DPI and the verdict. The table shows the largest size you can print and still look sharp.
What DPI do you actually need?
- 300 DPI — the print standard for anything viewed up close: printables, art prints, greeting cards, stickers, mugs and apparel.
- 150 DPI — fine for large pieces viewed from a distance, such as posters and banners.
- Below 150 DPI — usually looks soft or pixelated in print.
Why pixels matter more than the “DPI” saved in the file
Every image has a pixel size, like 3000 × 2400. Some files also store a DPI label (often 72 or 300), but that label does not change print quality on its own. What decides sharpness is simple: pixels ÷ print size = effective DPI. Print a 3000-pixel-wide image at 10 inches and you get 300 DPI; stretch it to 30 inches and you drop to 100 DPI. That effective DPI is exactly what this tool measures.
Frequently asked questions
Does this upload my image anywhere?
No. The whole check runs inside your browser using JavaScript. Your file is never sent to a server, so it stays completely private — you can even use it offline once the page has loaded.
What DPI do I need for Etsy digital downloads and printables?
300 DPI is the standard recommendation for printables, art prints, stickers and anything viewed up close. For large wall art viewed from a distance, 150 DPI is usually fine.
My file says 72 DPI — does that mean it is low quality?
Not necessarily. The DPI number saved inside an image file does not change how sharp it prints. What matters is the number of pixels divided by the print size. A 3000 × 3000 px image labelled "72 DPI" still prints at 300 DPI on a 10 × 10 inch print. This tool calculates that real, effective DPI for you.
What is the difference between DPI and PPI?
For digital artwork the terms are used interchangeably. PPI (pixels per inch) is technically the correct term for a screen image, while DPI (dots per inch) describes the printer. Buyers and marketplaces almost always say "DPI", so that is the term used here.
