Full API documentation

Explanation

Formula: PPI = 2631.8054639353572 x 2.54 / diagonal_cm. Why: this route fixes the resolution profile to Android FHD+ 2400x1080, so diagonal pixels stay constant for every calculation.

Android FHD+ 2400x1080: a fixed resolution profile with 2400 × 1080 pixels, used as the density basis for this page.

Diagonal size (centimeters): a screen-density quantity in this family that depends on the selected resolution profile.

Pixels per inch (PPI): a screen-density quantity in this family that depends on the selected resolution profile.

This route is useful when estimating screen sharpness, reading distance suitability, and display density for Android FHD+ 2400x1080.

This page is profile-dependent rather than universal because PPI, screen size, and pixel pitch depend on the selected resolution profile (Android FHD+ 2400x1080).

Method & Display Profile

Method basis: fixed Android FHD+ 2400x1080 pixel grid (2400 × 1080) with one constant diagonal-pixel count for this route.
Profile reference: Android FHD+ 2400x1080 (2400 × 1080), so size, PPI, and pixel-pitch values all stay tied to the same display grid.
Consistency rule: calculator output and common-value rows keep the same fixed display profile in both directions.
