TV Mounting Height Calculator
Estimate screen-center, bottom-edge, and top-edge mounting heights from eye height, viewing distance, viewing angle, and television height.
Formula
Screen center height = eye height + tan(viewing angle) x viewing distance.
About the TV Mounting Height Calculator
Estimate screen-center, bottom-edge, and top-edge mounting heights from eye height, viewing distance, viewing angle, and television height. This tool keeps the requested measurements separate and applies the named method instead of substituting an unrelated general estimate.
How the TV Mounting Height Calculator Works
The vertical sight-line offset is added to seated eye height, then half the physical screen height is added and subtracted for edge positions.
Formula
Screen center height = eye height + tan(viewing angle) x viewing distance.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Seated eye height (required) - enter in in.
- Viewing distance (required) - enter in in.
- Upward viewing angle (required) - enter in deg.
- Physical screen height (required) - enter in in.
Results Reported
The result panel reports the final answer and the intermediate quantities needed to check the calculation:
- Screen center height (in)
- Screen bottom height (in)
- Screen top height (in)
- Sight-line offset (in)

Accuracy and Limitations
Comfort depends on seating posture, recline, room use, and mount limits. Verify studs, cables, heat clearances, and manufacturer instructions.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
