Browser-only tool
Estimate image pixel density from real print or display size.
Drop in an image, enter the physical width or height, and get an instant PPI estimate with print guidance. Everything runs locally in the browser.

Physical size input
Enter width, height, or both. Aspect ratio can stay locked.
Upload an image to start. Once the image is loaded, the app will estimate PPI and show whether the selected size is suited for print or screen use.
Density estimate
X and Y values are shown separately, along with the limiting value used for print guidance.
Horizontal density — Pixels ÷ physical width
Vertical density — Pixels ÷ physical height
Effective print density — The lower of the two values
Print quality check Waiting for input Upload an image and add a physical size.
Common rules of thumb: around 300 PPI is strong for close-up print, 200–240 PPI is usually solid,
and 150 PPI can still work for larger pieces viewed from farther away.
Suggested max print sizes
These estimates are based on the image pixel dimensions alone.
At 300 PPI — Best for detailed print work
At 240 PPI — Balanced quality for most prints
At 150 PPI — Good for larger viewing distances
The max print size estimate updates as soon as an image is loaded.
What this helps with
- Check whether an image is dense enough for a planned print size.
- Compare a few common paper sizes without opening design software.
- Estimate how large an image can be printed before detail starts to soften.
- Keep image handling private by doing the work directly in the browser.
