SwitchExplanation
Formula: pixel_pitch_mm = (diagonal_inches x 25.4) / 4405.814340164597. Why: this route fixes the resolution profile to 4K UHD 3840x2160, so diagonal pixels stay constant for every calculation.
4K UHD 3840x2160: a fixed resolution profile with 3840 × 2160 pixels, used as the density basis for this page.
Diagonal size (inches): 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 4K UHD 3840x2160 resolution profile.
This page is profile-dependent rather than universal because PPI, screen size, and pixel pitch depend on the selected resolution profile (4K UHD 3840x2160).
