About this free screen pixel density tool
Calculate pixels per inch from screen resolution and diagonal inches. Developer utilities inspect or transform data locally rather than contacting the address or service shown in your input. Use fictional samples while checking a format, keep credentials out of shared screenshots and validate the result against the receiving system. Successful parsing does not establish trust, security or schema correctness.
A practical example
A concrete example uses horizontal pixels: 1920; vertical pixels: 1080; screen diagonal (inches): 24. The result is Pixels per inch: 91.787799.
Before you rely on the result
Results use floating-point arithmetic and are rounded to six decimal places. Confirm units and required precision before using the result. Use the active screen diagonal, not frame dimensions.
