Enter values to calculate DPI, pixels, or print size.
Calculate DPI from pixel and physical size, pixel dimensions from print size and DPI, or print size from pixels and DPI. Supports inches, centimeters, and millimeters.
Use the DPI / PPI Calculator form near the top of this page. Enter the values you know, run the tool, and review the results panel. You can change inputs and run it again. Processing stays in your browser and is not uploaded to Utilnivo servers.
Example: open DPI / PPI Calculator, enter a realistic set of inputs for your situation, and note the primary result. Change one input—such as an amount, rate, or option—and compare how the output changes so you can choose a scenario that fits your needs.
Second example: try edge cases that matter for your task—such as zero values, a different unit system, or a second file—and confirm the tool shows a clear result or a helpful validation message.
DPI and PPI are treated the same here: pixels per inch. Choose a mode to find resolution from pixel and print size, pixel dimensions from print size and DPI, or print size from pixels and DPI. Units can be inches, centimeters, or millimeters.
This tool runs in your browser for convenience. Results are estimates or transformations based on the inputs you provide and may not cover every edge case.
Yes. This calculator treats DPI and PPI as pixels per inch for print and screen planning.
