Monitor Size Comparison & PPI Calculator
Compare screen sizes and pixel density
Physical size overlay
Screen outlines are scaled proportionally to their physical dimensions and centered on the same point. PPI uses the pixel resolution and diagonal; physical width and height use the aspect ratio you enter.
About monitor size and PPI
Monitor size is usually described by its diagonal, but diagonal alone does not tell the whole story. Screens with the same diagonal can have different widths, heights and workspace depending on their aspect ratio.
Pixel density, measured in pixels per inch (PPI), describes how tightly pixels are packed across a display. Higher pixel density can make text and fine details look sharper, while viewing distance and display scaling also affect comfort.
This comparison helps when choosing monitors, laptops, televisions and phones. Enter each screen’s resolution, diagonal and aspect ratio to compare pixel density and physical dimensions in one view.
