How sharp a display actually looks, combining resolution with its physical size.
The same 1920×1080 resolution looks noticeably sharper on a 24-inch monitor than stretched across a 55-inch TV — PPI captures that difference by factoring in the physical screen size, not just the pixel count.
PPI (pixels per inch) describes a screen's pixel density; DPI (dots per inch) technically refers to printers — the terms get used interchangeably in casual conversation, but this calculator specifically computes screen PPI.
Pixel density (PPI)
91.788
Higher PPI means sharper, crisper detail — most phone screens are 300+ PPI, most desktop monitors are 90-110 PPI.

Diagonal resolution in pixels
√(1920² + 1080²)= 2202.9072 pxDivide by physical diagonal size
2202.9072 ÷ 24 in= 91.7878 PPIResult
Pixel density (PPI): 91.788
A 1920×1080 screen at 24" diagonal has a pixel density of 91.7877987534291 PPI.
