DPI & Print Size
Compute pixel size, print size, and image resize math
About this calculator
The DPI & Print Size Calculator relates pixel dimensions, DPI, and physical print size. Enter an image's width and height in pixels with a target DPI to get the print size in inches and centimetres, the total megapixels, and a print-quality verdict using standard print-shop buckets: draft below 150 DPI, ok to 225, good to 300, and excellent at 300 DPI and above. Non-positive dimensions or DPI return an error. Useful for photo printing and prepress checks.

Frequently asked questions
How does the DPI & Print Size tool work?
Enter or paste your input and the tool processes it directly in your browser, showing the result immediately. Nothing you type is uploaded to a server — the entire computation happens on your device.
When would I use the DPI & Print Size tool?
It is handy for development, debugging, design and administration tasks — whenever you need this transformation or check done quickly without installing anything or trusting a third-party service with your data.
How reliable are the results?
The tool implements the relevant standard or specification directly, so its output matches what compliant software produces. Edge cases such as empty or malformed input are reported clearly instead of failing silently.
Can I share a specific result with someone else?
Yes. Your input updates the URL, so copying the address bar and sharing the link reopens the tool in the same state for whoever clicks it.
