Rechner für TV-Maße aus Diagonale

How to use it: enter advertised diagonal, aspect ratio and an estimated bezel width. The calculator separates visible panel dimensions from approximate outside dimensions.

Formula. Scale factor = diagonal / sqrt(aspect width² + aspect height²); multiply each aspect term by that factor.

Example. A 65-inch 16:9 panel is about 56.65 x 31.87 inches before the bezel.

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.

• 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.

Manufacturers quote nominal visible diagonal. Bezel, chassis, stand and speaker dimensions vary, so use the model's dimension drawing before buying furniture or drilling mounts.
