Explanation

Formula: PPI = 3079.2395165040343 x 2.54 / diagonal_cm. Why: this route fixes the resolution profile to iPhone Pro 2796x1290, so diagonal pixels stay constant for every calculation.

iPhone Pro 2796x1290: a fixed resolution profile with 2796 × 1290 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 iPhone Pro 2796x1290.

This page is profile-dependent rather than universal because PPI, screen size, and pixel pitch depend on the selected resolution profile (iPhone Pro 2796x1290).

Method & Display Profile

  • Method basis: fixed iPhone Pro 2796x1290 pixel grid (2796 × 1290) with one constant diagonal-pixel count for this route.
