Full API documentation

Explanation

Formula: PPI = 3605.5512754639894 x 2.54 / diagonal_cm. Why: this route fixes the resolution profile to Tablet 3000x2000, so diagonal pixels stay constant for every calculation.

Tablet 3000x2000: a fixed resolution profile with 3000 × 2000 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 Tablet 3000x2000.

This page is profile-dependent rather than universal because PPI, screen size, and pixel pitch depend on the selected resolution profile (Tablet 3000x2000).

Method & Display Profile

Method basis: fixed Tablet 3000x2000 pixel grid (3000 × 2000) with one constant diagonal-pixel count for this route.
Profile reference: Tablet 3000x2000 (3000 × 2000), 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.
