I bought a big TV but it won’t hang up? Choosing the wrong rack is more troublesome than buying the wrong TV

Hanging a TV on the wall is something that many people want to do but dare not do when decorating - they are afraid that the wall is not strong enough, they are afraid of choosing the wrong hanger, they are afraid of drilling holes in the wrong position and causing the TV to become skewed, and what to do if it falls. In fact, as long as you understand a few key parameters, this matter is easier than imagined.

Rack type: three completely different uses

Fixed hanging rack

After installation, the TV is fixed without any angle adjustment.

Advantages: The strongest, cheapest, ultra-thin (the distance to the wall can reach 25mm)
Disadvantages: The angle cannot be adjusted after watching, and the viewing position is fixed
Suitable: Hang opposite the bed in the bedroom and opposite the sofa in the middle of the living room. The position is determined and no angle adjustment is required.

Tilt hanger

The angle can be adjusted up or down (typically ± 5–15°), but not left or right.

Suitable: The TV is positioned high (such as hanging above a fireplace) and needs to be tilted down for a comfortable viewing angle

Fully moving (rotating) hanger

It can tilt up and down + rotate left and right (usually ±90°), and the TV can be pushed away from the wall and pulled to different angles.

Advantages: Flexible, suitable for multi-viewing, L-shaped sofa layout
Disadvantages: Larger distance to the wall (at least 75–100mm), higher installation requirements
Note: High weight TV + swivel mount, more stringent requirements for wall and expansion bolts

VESA hole spacing: the most important parameter

VESA is the spacing standard for the mounting holes on the back of the TV, and the mount must match the VESA hole spacing of the TV.

Expression: VESA 200×200 means horizontal hole spacing 200mm, vertical hole spacing 200mm

TV dimensions	Common VESA hole spacing
32–43 inches	100×100, 200×100, 200×200
43–55 inches	200×200, 300×300, 400×200, 400×300
55–65 inches	400×400, 600×400
65 inches or more	600×400, 800×400, 800×600

How to check the VESA hole pitch of your TV:

Check the TV manual (usually on the specifications page on the back)
Check the product page on the official website and look for "Installation Interface Standards"
Directly measure the horizontal and vertical spacing of the four mounting holes on the back

Note: Mounts usually support a variety of VESA hole spacings. Make sure your TV's hole spacing is within the support range of the mount before buying.

Load-bearing capacity: There must be a margin

The maximum load-bearing capacity marked on the mount must be greater than the weight of the TV, and a safety margin of more than 50% is recommended.

TV Dimensions	Typical Weight
43 inches	6–10kg
55 inches	12–18kg
65 inches	18–28kg
75 inches	30–45kg
85 inches+	45–65kg

Example: A 65-inch TV weighs about 25kg, so you should choose a mount with a load capacity of ≥ 37.5kg (25×1.5).

Wall type: decide whether it can be hung and how to hang it

Concrete Solid Wall (Reinforced Concrete):

The strongest, you can directly use an impact drill to drill expansion bolts
There is no problem with load-bearing, as long as the expansion bolts are of the correct specifications, it can be hung

Brick Wall (Solid Brick):

Strong, expansion bolts can also be used
Be careful to avoid drilling holes in brick joints (brick joint mortar has low strength)

Hollow bricks or air-entrained concrete (ALC panels):

Poor load-bearing capacity, ordinary expansion bolts are unreliable
Special anchors for cavity walls (chemical bolts or flip bolts) must be used
It is recommended to consult the builder or property owner in advance to confirm the wall type

Gypsum board partition wall (light steel keel):

The load-bearing itself is extremely poor, and the thickness of the gypsum board is about 12mm
To hang a small TV (≤43 inches), you need to find the keel position and drive screws
When hanging a large TV (55-inch+), it is recommended to reinforce it in advance during decoration (add horizontal braces or steel plates)

How to determine wall type:

Concrete/brick walls have a dull sound when you flick the wall with your fingers; drywall has a loud hollow sound
Use magnets to find the location of keel screws (available on gypsum board partition walls)

Install height calculation

Most comfortable viewing height: Center of screen at eye level when seated, or 5–10° lower.

Calculation formula:

Eye height in sitting position is about 105–115cm (take 110cm as a reference)
Height of screen center from the ground ≈ 110cm
Mount mounting hole height = screen center height - Distance from top edge of TV to VESA center

Example: The height of a 55-inch TV is about 70cm, and the center of the screen should be about 110cm from the ground. Then the bottom edge of the TV is from the ground = 110 - 35 = 75cm

Common mistake: Hang the TV as high as the wall hanging in the hall (center at 150–160cm). Looking up for a long time will cause discomfort to the cervical spine.

Shopping list

Parameters	Confirmation matters
VESA hole pitch	Consistent with actual measurement on the back of the TV
Hanger type	Fixed/tilt/full motion, choose as needed
Maximum weight	≥ TV weight × 1.5
Wall type	Concrete/brick wall/gypsum board, determines installation method
Installation height	Screen center about 110cm
