TV Mounting Height Calculator
Turn your TV size and seated eye height into screen-center, bottom and top measurements from the floor.
Your measurements
Size shortcuts only—not model availability or recommendations.
Distance, bracket offset & clearance
Measure this offset on your actual TV and bracket. Mounting-hole positions are not inferred from screen size.
A geometric obstruction check only. Follow manufacturer, fireplace and mount safety instructions for actual required clearances.
Measurements and results stay in this browser tab. They are not uploaded, saved or automatically included in feedback. Refreshing clears entries.
Enter TV diagonal and your seated eye height to see mounting measurements.
How it works
- Measure eye height from the floor while seated in your usual viewing position. Enter TV diagonal and aspect ratio.
- Use Center at eye level, or enable above-eye-level placement and enter horizontal viewing distance and an upward angle.
- Optionally enter the actual bracket reference offset or a minimum bottom height to check an obstruction.
- Copy your measurements and verify the TV chassis, mount instructions and any required safety clearances before installation.
A real example
Fictional room example: a 65-inch 16:9 screen is approximately 56.7 × 31.9 inches. With seated eyes 42 inches above the floor, eye-level placement gives a screen center of 42 inches, bottom about 26.1 inches and top about 57.9 inches.
If the measured bracket reference is 5 inches below screen center, enter an offset of -5 inches. The reference height is then 37 inches—not 42 inches. A 40-inch minimum bottom clearance requires a screen center about 55.9 inches high; at a horizontal viewing distance of 120 inches, the resulting upward center angle is about 6.6°.
Your seated eye height, not a universal mounting height
Sit where you normally watch and measure vertically from the floor to your eyes. Furniture, posture and the viewer change this measurement. Center-at-eye-level mode uses your measurement directly; it does not promise a universally perfect or medically recommended height.
A TV’s diagonal runs corner to corner across the visible image. Its aspect ratio determines physical height; half that height falls above and half below the chosen center. For the same eye height, a 55-, 65- or 75-inch TV has the same center but different bottom and top measurements.
Screen center and bracket reference are different
The calculator describes the visible screen rectangle. The chassis and bezel may be larger. Mounting holes or a bracket’s reference line can sit above or below screen center; measure that relationship using the actual television and mount instructions.
The signed offset is added to screen-center height: positive is above, negative below. Feet + inches mode uses separate fields for ordinary lengths; the optional signed bracket offset uses decimal feet. Do not treat screen-center height as an automatic drilling position.
Above-eye-level placement and obstructions
The optional angle mode uses center = eye height + horizontal distance × tan(angle). An angle of 0° matches eye-level placement. Angle shortcuts are convenient entries, not ideal-angle recommendations. No viewing-distance recommendation is supplied.
An obstruction sets a minimum bottom height. The minimum screen center is that height plus half the visible screen height. The check reports overlap and, if distance is available and the minimum center is above eye level, its resulting upward angle. It does not automatically change your selected placement.
For a TV above a fireplace, mantel or console, this is geometry only. Follow manufacturer, fireplace and mount safety instructions for actual clearance requirements. Heat, chassis dimensions and installation rules are outside this calculator’s scope.
Frequently asked questions
How high should I mount my TV?
Start with your actual seated eye height and use it as the visible screen center in the default mode. Review bottom/top dimensions and real installation constraints. This is a measurement plan, not a universal ergonomic guarantee.
Does a larger TV need a different center height?
At the same seated eye height, the default center is unchanged. A larger screen extends farther above and below that center. The diagonal shortcuts do not recommend models or mounting heights.
Where should I install the wall bracket?
Check the actual TV and mount. Enter the signed vertical offset from visible screen center to your bracket reference point; the calculator adds it to center height. It does not infer VESA or mounting-hole positions.
Can I calculate a TV mounted above eye level?
Yes. Enable the secondary mode, enter horizontal viewing distance and an upward center angle below 90°. The calculator shows the vertical rise, center, bottom and top.
Is the bottom-clearance check a fireplace safety calculation?
No. It only compares the visible screen bottom to a height you supply. Obtain actual safety clearances from manufacturer, fireplace and mount instructions, including allowance for the larger chassis.
Are measurements saved or uploaded?
No. This calculator uses page memory and runs locally in the browser. Refreshing clears entries. Copy Results uses your clipboard or a manual-copy fallback; feedback does not automatically include measurements or results.
