DPI PPI Calculator
Calculate dots per inch and pixels per inch for print and screen resolution.
Whether a specific image will print sharp at a given size and how densely packed the pixels are on an actual physical screen are two different questions answered by the same underlying math, one asking whether a file has enough resolution for a print job, the other describing a display device's own specification, like why a phone advertised as "retina" packs noticeably more pixels per inch than an older, lower-density screen. This tool calculates dots per inch and pixels per inch for both print sizing and screen resolution, covering a display's own pixel density alongside whether a specific image file will hold up at a given print size.

Useful for calculating a monitor or phone screen's actual pixel density from its resolution and physical size, checking whether an image has enough resolution for a specific print size, or comparing two screens' pixel density specifications directly.
