What Size TV Mount Do I Need? Complete Guide
To find the right TV mount, you need to know two things: your TV's VESA pattern (the bolt spacing on the back) and its weight. Check the back of your TV or the manual — the VESA pattern is printed as something like "200x200" or "400x300."
That's the actual answer. Everything else is details, but those two numbers determine which mount fits your TV.
What the heck is a VESA pattern?
VESA stands for Video Electronics Standards Association. They standardized the bolt pattern on the back of TVs so mounts would be universal. The pattern is always described as width x height in millimeters.
When you look at the back of your TV, you'll see 4 screw holes arranged in a rectangle (sometimes a square). The distance between them is your VESA pattern.
You can measure it yourself with a tape measure: horizontal distance between the two top holes (in mm) x vertical distance from a top hole to the bottom hole below it (in mm).
Or just look it up. Here's what most common TV sizes use:
| TV Size | Typical VESA Pattern | Common Mount Size |
|---|---|---|
| 24-32" | 100x100 or 200x200 | Small |
| 40-43" | 200x200 | Small/Medium |
| 50-55" | 200x200 or 300x300 | Medium |
| 55-65" | 300x300 or 400x400 | Medium/Large |
| 65-75" | 400x400 or 600x400 | Large |
| 75-85" | 600x400 or 800x400 | Extra Large |
| 85"+ | 600x400 to 900x600 | Extra Large |
I say "typical" because manufacturers do whatever they want. We had a 55-inch TCL last week with a 400x200 pattern, which is unusual for that size. Always check your specific model.
The three types of mounts (and when each one makes sense)
Fixed mounts (flat/flush)
The TV sits flat against the wall with zero movement. Thinnest profile — usually about 1 inch from wall to TV back.
Use when: The TV is directly at eye level (center of screen at 42-48 inches from floor), you're mounting on a flat wall, and you'll always watch from the same spot.
Our pick: USX Mount Fixed Mount ($15-20 on Amazon). Stupid simple, holds up to 132 lbs, works with VESA up to 600x400. We've installed probably 600 of these.
Price range: $10-30
Tilting mounts
The TV can angle downward, typically 5-15 degrees. Profile is about 2-3 inches from the wall.
Use when: The TV is mounted higher than eye level (above furniture, above a fireplace), or the room has windows that cause glare you need to angle away from.
Our pick: Echogear EGLT1 ($25). Fits most TVs 32-70 inches, tilts 8 degrees, one-person installation.
Price range: $20-50
Full-motion (articulating) mounts
The TV extends from the wall on an arm, swivels left/right, tilts up/down, and sometimes rotates. Extension ranges from 8 to 28 inches depending on the model.
Use when: You watch from multiple spots (living room/kitchen), the TV is in a corner, you need to reduce glare from different angles throughout the day, or the TV is above a fireplace.
Our pick for most installs: Echogear EGLF2 ($80-90). Full motion, extends 22", fits 42-90" TVs up to 132 lbs. This is the mount on probably 40% of our full-motion installs. Smooth movement, solid build, good cable management clips.
For big TVs (75"+): USX Mount Full Motion for 75-100" ($55-70). Dual arm design distributes the weight better for heavy panels.

Weight rating matters more than size rating
Here's something I see customers get wrong constantly: they match the TV size to the mount size and ignore the weight.
A mount rated for 32-65 inch TVs might only handle 77 lbs. Most 65-inch TVs weigh 45-55 lbs, so that's fine. But some 65-inch models (looking at you, older Sony X950H at 74 lbs) cut it close.
Always check the weight rating. Then give yourself at least 20% margin. If your TV weighs 50 lbs, use a mount rated for at least 60 lbs.
We track this because it matters: in 6 years of doing this, the two mount failures we've seen were both weight-related. One was a 75-inch on a mount rated for 60 lbs. The other was an older 65-inch plasma (those things were heavy — 85+ lbs) on a standard mount.
How to check your TV's VESA pattern and weight
Three ways, from easiest to hardest:
The screw size is usually M6 for TVs under 55 inches and M8 for larger TVs. Most mounts include both sizes in the hardware pack.
One thing most guides skip: stud spacing
Your mount needs to attach to wall studs (unless you're going into brick/concrete). Standard stud spacing is 16 inches, but some homes — especially newer construction — use 24-inch spacing.
Most mounts accommodate 16" studs. Fewer handle 24" spacing. If your studs are at 24 inches, you need a mount plate wide enough to reach both studs, or a single-stud mount with a proper toggle bolt on one side.
We carry a stud finder on every job because the "16 inches from the last stud" rule fails about 30% of the time. Studs shift around windows, doors, corners, and outlets.
The quick-reference buying checklist
Before you order a mount, confirm these 4 things:
If all four check out, you're good. If any one is off, the mount is wrong.
FAQ
What VESA pattern is a 55-inch TV?
Most 55-inch TVs use a 200x200 or 300x300 VESA pattern. Samsung 55-inch models typically use 200x200. LG 55-inch models vary between 200x200 and 300x300. Always verify with your specific model number.
Can I use a mount that's rated for larger TVs on a smaller TV?
Yes. A mount rated for 40-85 inch TVs will work fine on a 50-inch TV, as long as the VESA patterns match. The mount just has a wider range of compatibility. There's no downside to going bigger on the mount rating.
Do all TV mounts fit all TVs?
No. TV mounts are specific to a VESA pattern range and weight rating. A mount designed for 100x100 VESA (small TVs) won't fit a TV with a 400x400 pattern. Always check both the VESA compatibility and the weight limit.
