Print size notes
The print size result is calculated from pixels divided by DPI, then converted to centimeters.
Use the result to decide whether to resize, crop or choose a different print size before exporting.

How it works
- 1Enter the image pixel dimensions.
- 2Choose the intended print DPI.
- 3Compare the resulting print size against your target.
Privacy and limits
- The calculator uses math only and does not upload images.
- Printers, paper and image sharpness can affect the final visual result.
- Upscaling an image can make the print softer even when the size math works.
Common use cases
- Photo print planning
- Poster and flyer image checks
- Preparing images for documents or forms
Print notes
- Higher DPI means a smaller physical print from the same pixels.
- Lower DPI allows a larger print but can look softer up close.
- Printer scaling and margins can change the final physical output.
Original test sample
- A 3000 x 2400 image at 300 DPI should read as 10 x 8 inches.
- Try the same pixels at 150 DPI to see how the print size doubles.
Frequently asked questions
Are my images uploaded?
No. ImgShrink processes selected images in your browser and does not upload them to a server.
Which DPI should I use?
300 DPI is a common high-quality print target, 150 DPI can work for general print, and 72 or 96 DPI is mainly screen-oriented.
Is this a final print or document approval check?
No. The calculator gives pixel, DPI and physical-size math. Printers, passport offices and upload portals may apply extra rules.
Source and compatibility notes
DPI and print-size results use standard pixel-to-physical-size formulas. Document-photo presets are reference sizes, not a substitute for official submission rules.
