TV Ophanghoogte & VESA Positie Calculator
Bereken het midden, de boven- en onderkant en de VESA-referentiehoogte van het scherm op basis van jouw werkelijke zichtlijn zittend.
Positive means the VESA centre is higher
How it works
How to use it: measure seated eye height and eye-to-screen distance. Choose a small upward sight angle if the screen centre must sit above eye level, then enter the manufacturer's VESA-centre offset.
Formula. Screen centre height = eye height + tan(sight angle) x viewing distance. Screen top and bottom add or subtract half the physical panel height.
Example. With a 65-inch TV, 40-inch eye height and zero-degree sight line, the centre is 40 inches high; the visible panel runs roughly 24.1 to 55.9 inches.
Current-input example
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 diagonal
- 65 in
- Seated eye height
- 40 in
- Eye-to-screen distance
- 96 in
- Sight angle above horizontal
- 0 deg
- VESA centre offset from screen centre
- 0 in
Primary result: Screen centre height: 40.0 in.
Before using the result
- 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.
Limitations
This calculates sight-line and screen geometry, not safe mounting. Use the TV and bracket drawings for chassis dimensions, VESA location and fasteners; verify wall structure, services, bracket capacity and local requirements before drilling.
Frequently asked questions
What does VESA offset mean?
Some TVs place the mounting-hole pattern above or below the visible screen centre. Enter that signed difference to turn screen-centre height into a bracket reference.
