Display Specs Lab
Calculate screen density and physical dimensions, compare displays, or prepare correctly proportioned digital content.
Use this when you need to
- Compare density across physical displays
- Calculate PPI, pitch and physical dimensions
- Prepare correctly proportioned social assets
What it does not replace
PPI does not measure brightness, color accuracy, refresh rate or overall panel quality. Viewing-distance estimates are orientation aids, not guarantees of perceived sharpness.

Density labels and retina distance are orientation aids, not guarantees of perceived quality. Vision, scaling, panel technology and content also matter.
Understand and Compare Resolution, Physical Size and Pixel Density
Resolution tells you how many pixels a display contains, while physical size determines how tightly those pixels are packed. Two screens can share the same resolution but look noticeably different because their diagonal measurements and pixel densities are not the same.
In Display Calculator mode, enter pixel width, pixel height, diagonal and viewing distance. Display Lab calculates exact and commercial aspect ratios, megapixels, PPI, physical width and height, pixel pitch, pixels per degree and an approximate retina distance. Comparison mode shows the relative density, pixel count and physical size of two screens.
Content Size mode keeps digital media separate from physical display calculations. Use its explicitly labeled Instagram, Facebook, TikTok, YouTube, Threads, X, and LinkedIn presets without assigning a misleading PPI value to a file that may appear on many screen sizes. Results can be copied, exported as a branded PDF report or compact PNG card, or shared through a URL containing the selected specifications. All exports are generated locally in the browser.
Use these measurements when choosing a monitor, comparing laptops, planning screen layouts or preparing media. Density descriptions and viewing-distance estimates are orientation aids rather than promises of image quality. PPI does not measure brightness, contrast, refresh rate, panel technology, operating-system scaling or color accuracy.
