SwitchExplanation
Formula: pixel_pitch_mm = 25.4 / PPI. 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.
Pixels per inch (PPI): a screen-density quantity in this family that depends on the selected resolution profile.
Pixel pitch (mm): a screen-density quantity in this family that depends on the selected resolution profile.
This route is useful when comparing panel sharpness and physical pixel spacing for the fixed iPhone Pro 2796x1290 resolution profile.
This page is profile-dependent rather than universal because PPI, screen size, and pixel pitch depend on the selected resolution profile (iPhone Pro 2796x1290).
