Full API documentation

Explanation

Formula: diagonal_cm = (2789.251512502951 / PPI) x 2.54. Why: this route fixes the resolution profile to iPhone Retina 2532x1170, so diagonal pixels stay constant for every calculation.

iPhone Retina 2532x1170: a fixed resolution profile with 2532 × 1170 pixels, used as the density basis for this page.

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

Diagonal size (centimeters): 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 Retina 2532x1170.

This page is profile-dependent rather than universal because PPI, screen size, and pixel pitch depend on the selected resolution profile (iPhone Retina 2532x1170).

Method & Display Profile

Method basis: fixed iPhone Retina 2532x1170 pixel grid (2532 × 1170) with one constant diagonal-pixel count for this route.
Profile reference: iPhone Retina 2532x1170 (2532 × 1170), 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.
