PixelCalc

PixelCalc

PPI, megapixel, print size & aspect ratio math

PixelCalc computes screen pixel density (PPI), megapixels, print size at any DPI, and aspect ratios. Type a resolution or pick a device preset and get exact math — including where marketed specs disagree with the arithmetic.

Technology · Productivity · Web development

Features

- PPI and total megapixels for any resolution/diagonal

- Print dimensions at any DPI with real paper presets

- Aspect ratio from any width/height pair

- Device preset library with verified spec math

- Runs fully client-side, no signup

Use Cases

Check a monitor spec before buying · size an image for a 300dpi print job · verify whether a panel is really the advertised PPI · compare aspect ratios for video projects

Hi! I built PixelCalc because every PPI calculator I tried rounded the spec-sheet marketing numbers instead of showing the real math. It also flags where advertised PPI disagrees with the resolution/diagonal arithmetic — useful before buying a monitor. Happy to hear what presets you would add.
