How to Measure TV Mount Hole Positions

The short answer

To measure TV mount hole positions accurately, establish the TV’s screen center, locate the centers of its VESA holes, and transfer those measurements through the mounted bracket to the wall. Do not assume the wall plate’s holes align directly with the TV’s holes: a mount may introduce vertical or horizontal offsets, especially when it has rails, hooks, tilt hardware, or swivel arms.

Before drilling, verify four things against the TV and mount manuals:

• The TV’s VESA pattern matches the mount’s supported patterns.
• The TV weight, including any accessories attached during installation, is within the mount’s stated capacity.
• The wall and fasteners are suitable for the mount and the intended load.
• The bracket’s screw, spacer, rail, and locking arrangement matches the TV.

If you are still choosing hardware, browse TV mounts and compare the mount’s installation drawings with your TV measurements.

What you need to measure

Gather:

• The TV and its model-specific specifications
• The mount’s installation manual and dimension drawings
• A tape measure or steel ruler
• A level
• Pencil or removable marking tape
• A straightedge or framing square
• A stud finder where applicable
• A helper for holding and checking the bracket
• The correct screws and spacers supplied or specified for the TV and mount

Measure in millimeters when possible. Small errors are easier to track when all measurements use the same unit.

Understand the two different hole patterns

A TV mount installation normally involves two separate geometries.

The TV-side VESA pattern

VESA measurements describe the horizontal and vertical distance between the centers of the threaded holes on the back of the TV. For example, a pattern written as 400 × 200 means:

• 400 mm between the left and right hole centers
• 200 mm between the upper and lower hole centers

These are center-to-center dimensions, not the outside dimensions of the mounting rails or brackets.

Record:

• Horizontal VESA spacing
• Vertical VESA spacing
• Distance from the VESA pattern to the top, bottom, and side edges of the TV
• Whether the holes are recessed
• Whether the rear of the TV needs spacers for clearance

Treat the manufacturer’s specifications as verified information. Do not estimate a VESA pattern from the outside dimensions of the TV.

The wall-side mounting pattern

The mount’s wall plate has its own hole locations. These may be:

• A fixed set of holes
• Long vertical or horizontal slots
• Multiple hole groups
• A rail system
• A plate that attaches to arms or hooks

Measure the wall plate from a clear reference point, such as its centerline or a specified edge. Then identify how the TV-side brackets hang on, hook onto, or attach to the wall-side assembly.

The distance from the TV’s VESA hole centers to the mount’s hanging point is the critical transfer measurement. Use the mount’s drawing when available rather than assuming the bracket is centered.

Establish the TV and screen center

The geometric center of the TV is found by dividing each outside dimension by two:

Screen center height = TV height / 2

Screen center width = TV width / 2

The VESA pattern is not always centered on the TV. It may sit higher, lower, or slightly off-center because of the TV’s internal components and rear housing. That is why measuring from the TV edge to the VESA holes matters.

Measure from the same edge each time. For example:

• Top edge to the center of the upper VESA holes
• Left edge to the center of the left VESA holes
• Bottom edge to the center of the lower VESA holes

If the two sides or top and bottom measurements differ, do not average them automatically. Check whether the TV’s housing is asymmetrical or whether the holes are recessed and difficult to identify.

Choose the target screen height

Decide where the TV’s screen center should sit before transferring any bracket marks. The correct height depends on viewing position, seating, furniture, speakers, windows, and clearances.

A useful planning approach is:

Top of TV = desired screen center height - (TV height / 2)

Then:

Bottom of TV = top of TV + TV height

These are planning calculations, not universal mounting rules. A comfortable viewing height in one room may be unsuitable in another. Account for:

• Eye level from the primary seating position
• A console or media cabinet
• A soundbar or center speaker
• Radiators, fireplaces, and ventilation
• Doors, windows, and cabinet doors
• The mount’s tilt range and any required clearance
• Cable bend space behind the TV

Keep the target centerline visible on the wall with a level horizontal mark. This line is a reference, not necessarily the location of any wall fastener.

Convert VESA measurements into wall marks

The safest way to transfer measurements is to use a coordinate system.

1. Mark the intended horizontal centerline of the screen.
2. Mark the intended vertical centerline of the TV.
3. Mark the TV’s VESA hole centers relative to those centerlines.
4. Attach the TV-side brackets to the TV, or hold them in their exact installed orientation.
5. Measure from the VESA hole centers to the mount’s hooks, rails, or wall-plate reference point.
6. Transfer that offset to the wall plate.
7. Place the wall plate so its final hanging position puts the TV center where intended.

A simple vertical calculation is:

Wall-plate reference height = desired screen center height + bracket offset

The sign depends on the mount’s design. If the wall-plate reference point sits above the TV’s VESA center when the TV is hanging, the offset moves upward. If it sits below, it moves downward. Confirm the direction by checking the mount in its actual orientation.

For the TV’s top and bottom edges:

Top edge height = TV center height - (TV height / 2)

Bottom edge height = TV center height + (TV height / 2)

These calculations help check the result, but the mount’s own hooks, rails, and adjustment range still determine the final wall marks.

Use a full-size template when possible

A paper, cardboard, or manufacturer-supplied template can reduce transfer errors. Mark the following on the template:

• TV centerline
• Screen top and bottom
• VESA hole centers
• Mount hooks or attachment points
• Wall plate holes or slots
• Cable and rear-clearance zones

Hold the template level at the planned position and confirm that the wall fastener locations fall where the wall structure can support them. A template is a layout aid, not proof that a particular wall or fastener is suitable.

Verify wall structure before drilling

Accurate measurements cannot compensate for an unsuitable wall attachment.

Identify the wall type and follow the mount manufacturer’s approved method for that construction:

• Wood studs: Locate the actual stud centers and confirm that the wall plate’s usable holes can align with them.
• Concrete or masonry: Use fasteners and drilling methods specified for the masonry type and mount.
• Metal studs: Do not assume they can support a TV mount without an approved reinforcement or attachment system.
• Drywall alone: Do not treat drywall anchors as automatically suitable for a TV mount. Check the mount instructions and the wall construction first.
• Plaster or unusual wall finishes: Account for the finish thickness and the condition of the material before selecting fasteners.

Never move a wall mark to a convenient location if doing so leaves the mount unsupported. If the wall plate does not align with suitable structural attachment points, reassess the mount, location, or reinforcement method before drilling.

Check screw depth, spacers, and rear clearance

The screw must fit the TV’s threaded insert and the mount’s bracket thickness without damaging the TV or failing to engage adequately. Do not select a longer screw simply because it appears to provide more engagement.

Check:

• Thread diameter and pitch specified for the TV and mount
• Required screw length for the TV’s rear recess
• Bracket thickness
• Spacer thickness
• Washer placement
• Whether the screw bottoms out in the TV before clamping the bracket
• Whether the screw contacts internal components
• Clearance around cable ports and the rear housing

Use only the screw and spacer combinations approved by the TV or mount documentation. If the supplied hardware does not fit correctly, stop and obtain confirmed replacement hardware rather than forcing the screw.

Tighten fasteners according to the manufacturer’s instructions. Avoid over-tightening, which can damage the TV’s threaded inserts or distort the bracket.

Account for tilt, swivel, and cable clearance

Measure the TV in the mount’s intended operating position, not only when it is flat against the wall.

A tilt or full-motion mount may need space for:

• HDMI, power, antenna, and network cables
• Cable connectors and strain relief
• Ventilation openings
• The TV’s rear housing
• Movement of the arm or tilt mechanism
• Access to the locking screws or release handles

Leave enough bend radius for cables. Do not compress a cable behind the TV or allow the mount to pinch it during adjustment.

For a swivel mount, check the full left and right travel before finalizing the location. The screen may need additional side clearance, and the mount may require a stronger or different wall attachment than a low-profile fixed mount.

Dry-fit and verify before drilling

A dry fit is a planning check using the assembled bracket without committing to holes.

Confirm:

• The wall plate is facing the correct direction.
• The bracket’s top and bottom are not reversed.
• The TV-side rails are at the intended spacing.
• The mount’s hooks or locking points are fully understood.
• The TV centerline lands on the planned wall centerline.
• The screen top and bottom clear nearby objects.
• The cables can be connected without sharp bends.
• The wall marks align with suitable structural attachment points.
• The bracket does not obstruct vents, ports, or controls.

Use a level in both directions. Check the wall, wall plate, and TV reference lines separately; a level wall plate does not guarantee a level TV if the TV-side brackets are installed unevenly.

Final locking and post-installation checks

After the mount is attached and the TV is hung or secured, complete the mount’s locking procedure. A TV that appears to be supported may not be fully engaged if its hooks, safety screws, or retention latches are not closed.

With a helper supporting the TV:

1. Confirm that both sides are seated on the mount.
2. Engage every required safety screw, latch, or locking mechanism.
3. Check that the TV cannot lift off or shift unexpectedly.
4. Confirm that cables are not trapped or under tension.
5. Test tilt or swivel movement gently within the stated range.
6. Recheck that the screen is level and centered.
7. Stop if the TV moves independently of the bracket or if any fastener does not tighten normally.

Do not use the TV as a lever to correct a badly positioned wall plate. Remove and reposition the installation only according to the mount’s instructions and with the TV supported.
