Key takeaways
- The bracket almost never sits at screen centre. Measure the offset on the assembled mount and subtract it from your eye-level mark, or the finished TV lands higher than you planned.
- Seated eye level beats any number off the internet. Sit in the seat you actually watch from, mark your eyeline, and build every other measurement from that mark.
- VESA is centre to centre, in millimetres. Measure the four threaded holes yourself if the manual's gone missing — horizontal first, then vertical.
- 16″ stud spacing is a starting guess, not a guarantee. Confirm every stud you drill into, especially in older Toronto housing stock and renovated walls.
- A 24-hour cardboard mock-up catches mistakes for free. Tape a template to the wall before the drill comes out — it's the cheapest insurance in this whole job.
Most TV mounting complaints aren't installation problems. They're measurement problems that only show up after the bracket's already on the wall — the screen sits higher than you pictured, or the holes you drilled don't line up with anything solid.
This page covers the measurements that actually decide whether that happens: where to put the centre of the screen, how to translate that into a bracket-hole position, how to read a VESA pattern, how to find studs you can trust, and how to test the height before you commit to a hole.

How High Should You Mount a TV? Find Your Seated Eye Level First
Forget the "42 inches from the floor" number you've probably already seen — it's a fine starting guess, not a target. The real rule is that the centre of the screen lands level with your eyes when you're sitting in the seat you actually watch from, relaxed, not leaning forward.
Sit down. Have someone hold a strip of painter's tape level with your eyeline against the wall, and mark it. That single mark, taken from your actual sofa in your actual room, beats any formula, because sofa height, how far back you sit, and how much the cushions have settled over the years all shift the number. In a condo with a lower ceiling, or a deep sectional you sit further back in, that mark can land anywhere from 38″ to 46″ — measuring beats guessing.
Two situations shift that mark on purpose. A bedroom TV watched from bed while propped on pillows sits higher than a living-room set, because your eyeline is higher too. A screen forced above a fireplace has to tilt down to compensate for the height it's stuck at — measuring won't fix a bad location, only a tilting bracket will.
Why the TV Ends Up Higher Than You Marked It: The Bracket Offset
Here's the part most guides skip, and it's the reason re-drilled holes happen: the point where the TV actually hooks onto the wall plate is almost never level with the screen's vertical centre. Mark the wall at your eye-level height and drill there, and the finished screen often ends up an inch or two higher than planned — because you marked where the plate should sit, not where the screen centre lands once the TV hangs off it.
The fix is one extra measurement, done before anything touches the wall:
- Lay the TV face-down on a blanket or its own box, and measure the full panel height, top edge to bottom edge, ignoring the stand.
- Mark the panel's true centre line — half that height, measured from the top.
- Attach the bracket's arms to the VESA holes, exactly as the mount's instructions describe.
- Measure from your centre-line mark to the wall plate's top edge (or the hook point the manual calls out), with the arms attached. Write that number down — it's your offset.
- Subtract the offset from your eye-level mark. If the plate sits 3″ below the screen's centre once assembled, mark the wall plate 3″ lower than your eye-level height, not at it.
The arithmetic
Wall-plate mark = seated eye-level height − bracket offset. A 55″ TV with a 3″ offset and a 42″ eye-level target gets its wall plate marked at 39″, not 42″. Skip this step and the screen lands at 45″ instead — noticeably higher, and the only fix is unscrewing everything and starting over.
The offset's size and direction depend entirely on your specific mount — low-profile fixed brackets, tilting mounts and full-motion arms are all built differently, so there's no universal number to memorize. If you're still choosing hardware, our guide to fixed, tilting and full-motion brackets covers how much offset each style typically introduces.
How to Measure Your TV's VESA Pattern
VESA is just the spacing between the four threaded mounting holes on the back of the panel, in millimetres, written as width×height. It's in your TV's manual, but if that's long gone, you can measure it yourself in under a minute with the TV face-down.
Measure the horizontal distance between the left and right holes, centre to centre, then the vertical distance between the top and bottom holes, centre to centre. Round to the nearest standard size — TVs don't usually land on odd numbers.
| Screen size | Typical VESA pattern |
|---|---|
| Up to 32″ | 75×75 mm or 100×100 mm |
| Up to 55″ | 200×200 mm or 300×300 mm |
| 55″–65″ | 400×400 mm |
| 65″ and up | 600×400 mm or 800×400 mm |
Treat that table as a rough guide, not a substitute for measuring — manufacturers don't all follow it, and a mismatch between your mount's supported range and your TV's actual pattern is the single most common reason a bracket won't fit a newer set.
Finding and Marking Wall Studs at the Right Height
Once you know your wall-plate height, run a stud finder horizontally along that exact line, not above or below it — studs aren't guaranteed to stay perfectly vertical over their full height, especially in older houses. North American residential framing puts studs 16″ on centre, though some builds use 24″.
A stud finder reads density, so it flags plumbing, ductwork and drywall seams with the same confidence it flags actual timber. Confirm what it finds by lightly knocking along the wall — solid over a real stud, hollow either side of it — before you commit to a mark.
Toronto adds a couple of local wrinkles worth knowing before you start. Condo and newer-build walls are frequently poured concrete behind a thin skim of drywall — a stud finder won't find studs because there aren't any, and you're into concrete-specific anchors instead. Plenty of newer partition walls also use steel studs, which read differently on a standard stud finder and need the right bit and fastener. Older Toronto housing stock brings the opposite problem: lath-and-plaster behind the paint, which behaves differently under a stud finder and a drill than modern drywall — see our plaster wall mounting guide if that's what you're working with.
Whatever the wall type, mark the centre of every stud you plan to use, not just the first one you find. Confirm each one rather than assuming the 16″ interval holds all the way across.
The Cardboard Mock-Up: Test the Height Before You Drill
Every measurement above is still a prediction until you've looked at it in the room. Cut a piece of cardboard — a flattened moving box works fine — to the TV's actual width and height, and tape it to the wall at your calculated position with painter's tape.
Then leave it there. Walk past it, watch TV on the couch with it up, look at it after dark with the lights on. A height that looks right for thirty seconds standing in front of the wall can look wrong once you're actually sitting down for two hours. Give it at least a day before you trust it.
Check this before you drill, not after
If the mock-up sits over an outlet, a light switch, or a cold-air return, that's easier to solve on cardboard than on a drilled TV. The same goes for a stud position that lands right at the mock-up's edge instead of somewhere useful along it — better to shift the whole layout a few inches now.
Once the mock-up passes, transfer its centre line and edges onto your final marks, and confirm your stud and bracket-offset numbers still agree with it before you pick up the drill.
Measure It Yourself, or Call Someone Instead?
The measurements on this page cover a standard drywall wall, a standard fixed or tilting bracket, and a TV you can safely hold up on your own. If that's your situation, a tape measure, a stud finder and an afternoon get you there.
Call someone when the wall changes the rules: concrete or brick behind the drywall, steel-framed partitions, a fireplace surround, or a panel large enough that lifting it alone isn't safe. It's also worth a call if your VESA, bracket-offset and stud numbers don't agree with each other no matter how many times you re-measure — that usually means one of the three is wrong, and a second pair of eyes finds it faster than a fourth remeasure.

Frequently Asked Questions
How high should a TV be mounted?
Put the centre of the screen at seated eye level for the seat you actually watch from. In a typical living room that lands somewhere around 42″ from the floor, but it varies with sofa height and how far back you sit.
Sit down, have someone mark your eyeline on the wall, and build the measurements from that mark rather than from a number off the internet.
What is the best height for a wall mounted TV?
The best height is the one that puts the middle of the picture level with your eyes when you're seated and relaxed. Mounting higher than that is the most common regret we're called back to fix.
Two exceptions: a bedroom TV watched while propped up on pillows sits a little higher, and a screen above a fireplace has to be tilted down to compensate for the height it's forced into.
How do I measure my TV for a wall mount?
You need three things: the screen diagonal, the weight without the stand, and the VESA pattern on the back. All three are in the manual. The VESA figures are the centre-to-centre distances between the four threaded holes, in millimetres.
Why did my TV end up higher than I marked?
Because the point where the TV hooks onto the wall plate usually isn't level with the centre of the screen. Measure the vertical distance between the bracket's top rail and the middle of the panel, and offset your wall mark by that amount.
How far apart are wall studs?
Normally 16″ on centre in North American residential framing, though 24″ is used in some builds. Once you've found one stud, measuring at that interval usually predicts the next — confirm each one rather than assuming.
How far from the wall should the TV sit?
That's set by the mount, not by you: about an inch for a slim fixed bracket, up to three inches for a folded full-motion arm. It matters most in an alcove or a recess, where the mount's depth plus the panel's thickness has to clear the opening.
Do I need a laser level?
It helps, but a decent long spirit level does the job. What matters is checking level across both fixing points rather than at one end, because a bracket that's level over 6″ can still be visibly out over 24″.
How much clearance should I leave around the TV?
Enough for airflow at the top and sides, and enough below for a soundbar if you're fitting one. If the screen sits in an alcove or recess, check the mount's depth plus the panel's thickness against the opening before you drill anything.
