How High to Mount a TV With the Ideal TV Height Formula
If you need to know how high to mount a TV on the wall 📺, this TV mounting height calculator helps you find the ideal TV height. Have you ever asked yourself: how high should I mount a TV? If so, this is the perfect place to get the answer.
It doesn't matter if you've just scheduled a binge-watching session or simply want to see a single movie or sporting event. Our tool tells you the best height for the TV, considering the viewing distance and the tilt angle (also known as the reclining angle). It works in both imperial (inches) and metric (centimeters) units. Let's start!

The Ideal TV Height Formula
There is an easy way to estimate how high a TV should be mounted. Here is the optimal TV height formula:
TVH = WH + HWD × tan(Φ)
where:
- TVH is the ideal TV height (the center of the screen);
- WH is the watching height — the level of the viewers' eyes 👀;
- HWD is the horizontal watching distance 📏; and
- Φ is the tilt angle.
You can derive this equation by applying an appropriate trigonometric function (the tangent) to the right triangle formed by your line of sight. Yup, here is the practical use of trigonometry in real life!

How to Find the Best Height for a TV
As we know how high to hang a TV, it's reasonable to ask why the TV mounting height equation remains as it is.
One of the crucial factors is the watching height. We assume it's best to watch a screen when it's at the same height as your eyes — at least when you are sitting straight. If your head tilts back when sitting on the sofa or the armchair 🛋️, the ideal TV height naturally increases.
"How high should I mount my TV then?" — you may ask. Our TV mounting height calculator is here to help!
When the tilt angle is zero, the TV mount on the wall equals the watching height. If the tilt angle is greater than zero (usually between 10° and 20°), then you can imagine three lines that form a right triangle 📐:
- The horizontal distance between the viewer and the TV;
- The vertical one from eye-level to the center of the TV; and
- The one between your eyes and the TV's center (your line of sight).
The ratio between the vertical and horizontal lines equals the tangent of the tilt angle, so the additional height above eye-level is h = HWD × tan(Φ). Finally, the total height of the TV on the wall is the sum of these values — precisely the ideal TV height formula from the section above.
How to Use Our TV Mounting Height Calculator
- Pick your measurement system — imperial (inches) or metric (centimeters).
- Enter the watching height — the height of your eyes above the floor when you're seated (typically around 42 in / 107 cm).
- Enter the horizontal watching distance from your seat to the TV wall.
- Enter the tilt angle Φ — how far you recline / look upward. Use 0° if you watch sitting perfectly straight, or 10°–20° for a relaxed sofa position.
- Optionally, tick "Add TV size" and enter your TV diagonal and aspect ratio to also get the exact bottom-edge mounting height — the number you actually measure from the floor when hanging the bracket.
The calculator returns the ideal height of the screen center, plus the top and bottom edges of the TV when you provide a screen size.
Worked Example
Suppose your eyes are 42 in above the floor, you sit 120 in (10 ft) from the wall, and you recline at a 15° tilt angle:
- Extra height above eye-level: h = 120 × tan(15°) = 120 × 0.2679 ≈ 32.15 in
- Ideal TV height (center): TVH = 42 + 32.15 ≈ 74.15 in (188.3 cm)
For a 55" 16:9 TV (screen height ≈ 27 in), the bottom edge sits at about 74.15 − 13.5 ≈ 60.7 in from the floor.
Frequently Asked Questions
How high should a TV be mounted?
As a rule of thumb, the center of the TV should be at your seated eye level — usually 42 in (107 cm) from the floor. If you recline, add HWD × tan(Φ) to raise the screen center to match your upward gaze.
What is the tilt angle?
The tilt angle Φ is how far your line of sight points upward from horizontal when you look at the screen center. Sitting straight it is 0°; relaxing on a sofa it is often 10°–20°. Physically tilting the TV panel down toward you lets you use a larger angle comfortably.
Does the TV size matter for mounting height?
The center height does not depend on TV size, but the bottom-edge height does. A bigger screen means the bottom edge sits lower for the same center height, so enter your diagonal and aspect ratio for an exact bracket measurement.
How high to mount a 65-inch TV?
The center still goes at your (tilt-adjusted) eye level. For a 65" 16:9 TV the screen is about 32 in tall, so the bottom edge sits roughly 16 in below the center height you calculate here.
