Pixels to inches notes
Pixels do not have a physical size until a DPI value is chosen.
This page keeps the calculation visible so you can compare inch, centimeter and DPI values.

- 2Set the DPI value used for the conversion.
- 3Use the inch result for print or layout planning.
Privacy and limits
- Pixel-to-inch conversion depends on the DPI you choose.
- The calculator does not inspect printer profiles or physical paper margins.
- Image upload is optional and only reads dimensions locally.
Common use cases
- Preparing image dimensions for print shops
- Checking photo print sizes
- Translating design specs into physical units
Conversion notes
- Formula: inches equals pixels divided by DPI.
- Width and height are calculated independently.
- Use centimeters when the target form asks for metric dimensions.
Original test sample
- 1200 pixels at 300 DPI equals 4 inches.
- 2480 x 3508 pixels at 300 DPI is close to A4 size.
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.
