About the DPI Calculator
The DPI Calculator computes dots per inch from a resolution (pixel width × height) and a screen/print diagonal (inches). DPI/PPI determines display or print sharpness. It also shows the dot pitch (mm).
Useful for print design, monitor choice, and asset preparation.
FAQ
Is this DPI Calculator accurate?
Yes. It uses standard formulas and runs directly in your browser at full JavaScript precision (plus BigInt/decimal.js for large numbers where needed).
Is my data sent to a server?
No. All calculations happen entirely on your device. No values are sent to or stored on our servers.
