Asking "how high should I mount my TV?" is the wrong question. The right question is: "how high should the center of my TV be?" Every other measurement (top of TV, mount holes, bracket position) flows from that one number. Here's the formula our installers use on every job, plus a quick-lookup chart for the most common TV sizes.
The One Rule: Center of TV at Seated Eye Level
The science is settled. Studies on neck strain and viewing comfort consistently show that the center of the screen should sit at the eye level of a seated viewer. For most adults on most couches, that's 42 inches from the floor.
This is also the standard our team has used across 10,000+ installs in Metro Atlanta — and the one customers come back and thank us for.
The Formula
To find the height of the bottom of your TV (which is what matters when you're at the wall with a level):
Bottom of TV = Seated eye level − (TV screen height ÷ 2)
Where:
- Seated eye level = typically 42" for adults on a standard 18"-tall couch
- TV screen height = roughly 0.49 × diagonal size for 16:9 TVs (we'll do the math for you below)
Quick Calculator: Bottom of TV Height by Size
Use these numbers if your seated eye level is the standard 42":
- 43" TV: Screen height ~21". Bottom of TV at 31.5" from floor
- 50" TV: Screen height ~24.5". Bottom of TV at 29.75"
- 55" TV: Screen height ~27". Bottom of TV at 28.5"
- 60" TV: Screen height ~29.5". Bottom of TV at 27.25"
- 65" TV: Screen height ~32". Bottom of TV at 26"
- 70" TV: Screen height ~34.5". Bottom of TV at 24.75"
- 75" TV: Screen height ~37". Bottom of TV at 23.5"
- 77" TV: Screen height ~38". Bottom of TV at 23"
- 82" TV: Screen height ~40.25". Bottom of TV at 21.9"
- 85" TV: Screen height ~42". Bottom of TV at 21"
- 98" TV: Screen height ~48". Bottom of TV at 18"
For ergonomic comfort, never let the bottom of any TV drop below 18"–20" off the floor — kids, pets, and toes will find it.
Adjustments for Your Specific Situation
Tall couches (sectional + recliner)
Your seated eye level might be 44"–46". Add the difference to every number above.
Bar-height seating
Counter stools and bar seating put eyes at 50"–55". Re-run the formula with your actual eye level.
Bedroom TVs (viewing from bed)
Reclined viewing eye level on a king mattress is roughly 36". Mount the center of the TV around 36" — meaning a 65" TV's bottom edge sits at about 20" from the floor.
Above a fireplace
You almost certainly can't follow the formula — the mantel forces the TV higher. Use a tilt mount with 10°–15° downward angle, or solve it properly with a MantelMount pull-down that drops the TV to ergonomic height for actual viewing.
Far seating distance
If your couch is 12+ feet from the TV, you can mount slightly higher (add 4"–6") because the steep viewing angle softens.
Couch-to-TV Distance: The Other Half of the Equation
For best viewing comfort, follow the THX recommended distance:
- 43" TV: 5.5 ft viewing distance
- 55" TV: 7 ft
- 65" TV: 8.5 ft
- 75" TV: 10 ft
- 85" TV: 11 ft
- 98" TV: 13 ft
If you're closer than these distances, your TV is "too big" — but the height formula still applies.
Mounting the Bracket vs. Mounting the TV
The numbers above are for the bottom edge of your TV. Your bracket goes behind the TV — usually with the bracket center 4"–8" above the TV bottom. Always test-fit by holding the TV against the wall before drilling. (Or skip the math and call us — we use a laser level on every Metro Atlanta install.)
Common Mistakes
- Eye-level for standing viewers: Don't do this — you'll spend 99% of viewing time looking up.
- Matching the height of an old smaller TV: Bigger TVs need lower bottom edges to keep centers at eye level.
- Using showroom heights: Stores mount TVs high to avoid theft and damage. Useless for home reference.
- Forgetting the soundbar: If a soundbar sits below the TV, the TV needs to go up by the soundbar height.

Frequently Asked Questions
How high should a 65-inch TV be mounted?
Bottom edge at ~26 inches from the floor — putting the center at standard 42-inch seated eye level.
How high should a 75-inch TV be mounted?
Bottom edge at ~23.5 inches from the floor for standard couches.
Is 60 inches too high for a TV?
For most living rooms with couches, yes — 60 inches to the center puts the bottom of a 65" TV at 44", which causes neck strain over long viewing.
What if my fireplace forces the TV too high?
Use a tilt mount with 10°–15° downward angle, or install a MantelMount pull-down to bring the screen to ergonomic height.
Does the height change for a bedroom TV?
Yes. For viewing from bed, mount the center of the TV at ~36 inches — about 6 inches lower than a living room install.
