Rechner für TV-Größenvergleich

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.

The result above uses these exact values. This snapshot is included when the page is printed so the output can be checked against the original measurements.

TV A diagonal

55 in

TV B diagonal

75 in

Viewing distance

96 in

Target viewing angle

36 deg

Primary result: Screen area increase: 86.0 %.

• 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.

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