How to Measure VESA Pattern
If you are buying a wall mount, desk arm, or stand, knowing how to measure VESA pattern is the fastest way to confirm compatibility.
The VESA standard looks simple, but a few easy mistakes can lead to the wrong bracket size, poor fit, or unstable mounting.
VESA patterns are used by manufacturers such as Samsung, LG, Sony, Dell, HP, and ASUS to standardize the distance between mounting holes on TVs and monitors.
Once you understand the basics, you can identify the correct mount size in minutes and avoid returning hardware later.
What Is a VESA Pattern?
A VESA pattern is the rectangular spacing between the four mounting holes on the back of a display.
The pattern is usually listed in millimeters as width by height, such as 75 x 75, 100 x 100, 200 x 200, or 400 x 400.
The term comes from the Video Electronics Standards Association, the organization that helped standardize display mounting interfaces.
In practice, the pattern tells you which mounts, brackets, and arms will line up with your device’s screw holes.
- 75 x 75 mm: common on smaller monitors and lightweight displays
- 100 x 100 mm: one of the most common monitor patterns
- 200 x 200 mm: often used on mid-size TVs
- 400 x 400 mm and larger: common on many large TVs
What You Need Before Measuring
You do not need special tools to measure a VESA pattern.
A ruler or measuring tape marked in millimeters is enough, though a caliper can help with precise measurements.
- A ruler or tape measure
- A screwdriver, if a stand or bracket is blocking the holes
- Paper and pen to record the measurements
- The display’s model number, if you want to verify the manufacturer specs
Always measure the hole centers, not the edges of the holes or the outer frame of the device.
That detail is where many people make mistakes.
How to Measure VESA Pattern Step by Step
1. Locate the four mounting holes
Turn the monitor or TV around and find the four threaded holes on the back.
They are usually arranged in a square or rectangle and may be hidden behind a cover, stand, or decorative panel.
2. Measure the horizontal distance
Measure from the center of the left hole to the center of the right hole.
Record the distance in millimeters.
This is the first number in the VESA pattern.
3. Measure the vertical distance
Measure from the center of the top hole to the center of the bottom hole on the same side.
Record this in millimeters as the second number in the pattern.
4. Write the pattern as width by height
Combine the measurements into the standard format.
For example, if the holes are 100 mm apart horizontally and 100 mm vertically, the VESA pattern is 100 x 100.
5. Confirm thread size if needed
Some mounts also require the correct screw size and length.
Common VESA mounting screws include M4, M6, and M8, depending on the display size and manufacturer design.
If the screws are too long, they can damage internal components.
How to Measure VESA Pattern on a TV
TVs often have larger patterns than computer monitors, and the mounting holes may be recessed deeper into the panel.
If a stand or cover blocks access, remove it carefully before measuring.
For larger televisions, the VESA pattern may be printed in the manual or listed on the product specification page.
Brands like LG, Samsung, TCL, Hisense, and Sony usually include the pattern in the technical details, along with the recommended screw type and maximum load rating.
- Check the rear panel for hidden or recessed holes
- Look in the user manual or manufacturer spec sheet
- Verify the mount’s weight capacity as well as the hole spacing
If the TV is curved, unusually slim, or has an off-center stand, measuring directly becomes more important because the mounting area may not be obvious.
How to Measure VESA Pattern on a Monitor
Monitors often use smaller VESA patterns, especially 75 x 75 and 100 x 100.
Many office displays from Dell, Lenovo, HP, and Acer include a straightforward four-hole layout, but some ultrawide or gaming monitors use less common patterns or require an adapter plate.
If your monitor came with a proprietary stand, remove it to expose the mounting holes.
Then measure center to center in both directions.
If the holes form a square, both measurements will match.
If they form a rectangle, the two values will differ.
Some monitors advertise “VESA compatible” but still require a bracket to convert a nonstandard backplate into the standard hole spacing.
Checking the exact model number helps avoid confusion.
Common VESA Sizes and What They Mean
Understanding common VESA sizes makes shopping easier because many product listings describe compatibility by these standard dimensions.
- 75 x 75 mm: compact monitors, portable displays, small TVs
- 100 x 100 mm: mainstream monitors and many 24-inch to 32-inch displays
- 200 x 100 mm: some larger monitors and medium TVs
- 200 x 200 mm: smaller flat-panel TVs and some all-in-one displays
- 400 x 200 mm, 400 x 400 mm, 600 x 400 mm: larger televisions
Mounts sometimes support multiple patterns, such as 75 x 75, 100 x 100, and 200 x 200, using adjustable brackets.
That flexibility is useful, but the mount still has to support the display’s weight and depth.
How to Verify the Pattern Without Measuring?
If you do not want to measure manually, check the display’s manual, manufacturer website, or product box.
Search the model number along with “VESA mount” or “mounting interface.” Retailer spec pages from Amazon, Best Buy, Newegg, and major office supply stores often list the same detail, though the manufacturer source is usually more reliable.
Another option is to use the mount manufacturer’s compatibility lookup tool.
Brands such as Ergotron, Mount-It!, and Sanus often provide calculators or fit charts that match display models to mounting hardware.
Common Mistakes When Measuring VESA Pattern
- Measuring from hole edges instead of centers: this produces the wrong spacing
- Using inches instead of millimeters: VESA is standardized in millimeters
- Ignoring recessed holes: deep recesses can affect screw length and bracket clearance
- Assuming all four holes are the same on every display: some models use adapters or nonstandard layouts
- Skipping weight and tilt limits: hole spacing alone does not guarantee safety
It is also important to check whether the back of the display is flat enough for the mount.
Some TVs have curved backs, speaker housings, or cable covers that interfere with the bracket.
How to Choose the Right Mount After Measuring?
Once you know the VESA pattern, compare it with the mount’s supported range and weight rating.
A mount may fit the hole spacing but still be unsuitable if the display is too heavy, too large, or has an unusual depth.
- Wall mounts are ideal when you want a clean, fixed setup or a tilting/swiveling arm
- Desk mounts work well for monitors, especially in home offices and multi-monitor setups
- Full-motion mounts provide the most flexibility but require stronger hardware
For very large TVs, make sure the wall surface can support the load, especially if you are mounting to drywall, brick, or a stud wall.
Use anchors, lag bolts, or masonry hardware that matches the surface and the mount instructions.
Why Accurate Measurement Matters
Measuring correctly protects your display, saves time, and helps you avoid returns.
A mismatch can cause unstable mounting, stripped threads, or a bracket that simply will not line up.
When you know how to measure VESA pattern accurately, you can shop with confidence, compare mounts more efficiently, and install your screen with fewer complications.
