G: TL;DR:
Yes—too high is the most common mistake.
For a normal seated setup at ~6–8 ft, you want the **center of the TV roughly at eye level (~40–42 inches from the floor)**. If it’s noticeably above that, it starts feeling awkward fast.

The core rule (the one that actually matters)

Aim for center of screen ≈ your seated eye level
For most adults sitting normally: ~40–42 inches from floor citeturn0search1turn0search8

Alternate phrasing (same idea):

Your eyes should land around the middle or slightly below middle of the screen citeturn0search9

What “awkward” actually looks like

You’ll feel it when:

You have to tilt your head upward instead of looking straight
Your eyes land in the bottom third of the screen or lower
It feels like watching a bar TV or waiting room screen

There’s a practical threshold:

Once your eye line drops below the bottom third of the screen, comfort starts to degrade noticeably citeturn0search9

For your specific setup (office, 6–8 ft)

That distance is normal—nothing special needed.

So your target is basically:

Sit in your chair
Look straight ahead (neutral neck)
Mark that height on the wall → that’s your screen center

Everything else (TV size, mount, etc.) just builds around that.

Quick sanity check numbers

These help you visualize before drilling:

Center of TV: ~40–42 inches from floor
That usually puts:
- Bottom of TV: ~22–28 inches (depends on size)
- Top: comfortably within eye range

If your mount plan puts the center closer to 50+ inches, you’re entering “this will feel off” territory unless you’re reclining or standing.

Third option (often overlooked)

There are cases where higher is fine:

Standing desk / frequent standing use
Reclined seating
Secondary/background TV

But for a desk + chair office setup, those don’t apply—so stick to eye level.

Practical trick (worth doing)

Tape outline test:

Put painter’s tape rectangle on the wall (TV size)
Sit normally
Adjust until it feels “invisible” to your neck

That will beat any formula.

If you want, give me your TV size and chair height and I’ll give you exact bottom-edge placement so you don’t have to eyeball it.
