Fonctionnement

How to use it: enter two TV diagonals and one seat distance. The overlay and metrics compare how much wall space, visible area and horizontal viewing angle each setup creates.

Formula. Width and height come from 16:9 diagonal geometry. Area increase = (B area / A area - 1) x 100. Viewing angle uses 2 x atan(width / (2 x distance)).

Example. Moving from 55 to 75 inches increases visible area by about 86%, not merely the 36% increase suggested by diagonal alone.

Avant d’utiliser le résultat

  • Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
  • Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
  • When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.

Limites

This compares physical screens, not picture quality, price, brightness, panel technology or room aesthetics. Manufacturer chassis dimensions and stands remain model-specific.

Questions fréquentes

Why does area grow faster than diagonal?

For the same aspect ratio, both width and height scale with diagonal, so area scales with diagonal squared.
