Explanation

Formula: pixel_pitch_mm = 25.4 / PPI. Why: this route fixes the resolution profile to UWQHD 3440x1440, so diagonal pixels stay constant for every calculation.

UWQHD 3440x1440: a fixed resolution profile with 3440 × 1440 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 UWQHD 3440x1440 resolution profile.

This page is profile-dependent rather than universal because PPI, screen size, and pixel pitch depend on the selected resolution profile (UWQHD 3440x1440).

Method & Display Profile

  • Method basis: fixed UWQHD 3440x1440 pixel grid (3440 × 1440) with one constant diagonal-pixel count for this route.
  • Profile reference: UWQHD 3440x1440 (3440 × 1440 display grid).
  • Consistency rule: calculator output and common-value rows keep the same fixed display profile in both directions.
