What Vesa Size Means
VESA sizeshows the distance between the mounting holes on the back of a monitor. It is measured in millimeters (mm). This size helps to find the right wall mount or stand for your screen.
The VESA size is shown as two numbers, such as 100 x 100 mm. The first number is the horizontal distance. The second number is the vertical distance between holes.
Knowing the VESA size is important to ensure your monitor fits securely on a mount or arm. It helps avoid buying the wrong bracket.
- Common VESA sizes: 75 x 75 mm, 100 x 100 mm, 200 x 200 mm
- Check the monitor’s manual or back panel for VESA size
- Use a ruler or tape measure to find hole spacing

Tools Needed For Measurement
To measure the VESA sizefor your monitor, you’ll need a few tools. A measuring tapeis essential to find the exact distance between holes. Make sure it is flexible for easy handling.
A screwdriveris also necessary. It helps remove the monitor’s back panel if needed. Use a rulerto double-check the measurements. This ensures accuracyin your findings.
Take notes on a notepador use your phone. This helps you remember the dimensions. These tools make measuring the VESA size simple and precise.
Locating Vesa Mount Holes
VESA mount holes are small holes found at the back of a monitor. They are used to attach the monitor to a stand or wall mount. These holes form a square or rectangle pattern. The distance between the holes is important. It tells you the VESA size.
Most monitors have four holes. They are arranged in a square or rectangle. Use a ruler or tape measure to find the distance between holes. Measure horizontally and vertically from center to center.
Common VESA sizes include:
- 75 x 75 mm
- 100 x 100 mm
- 200 x 100 mm
- 200 x 200 mm
Some monitors may have no holes. These do not support VESA mounts. Check your monitor’s manual if unsure.
Measuring Horizontal Distance
Measure the horizontal distancebetween the four mounting holes on the back of the monitor. Use a ruler or tape measure. The measurement is usually in millimeters (mm). This distance tells you the width of the VESA mount.
Make sure to measure from the center of one hole to the center of the opposite hole. This is the standard way to find the VESA size.
- Common VESA widths are 75mm, 100mm, 200mm, and 400mm.
- Write down the exact measurement for later use.
- Do not guess or estimate; accurate measurement is key.
Measuring Vertical Distance
Measure the vertical distance between the mounting holes on the back of the monitor. Use a ruler or tape measure for accuracy. Only count the distance between the centers of the holes. This vertical space tells you the VESA size height.
Common VESA vertical sizes include 75 mm, 100 mm, 200 mm, and 400 mm. Match this measurement with the monitor mount or stand specifications. Make sure the mount supports the vertical hole spacing exactly.
- Place the ruler at the center of the top hole
- Measure straight down to the center of the bottom hole
- Record the measurement in millimeters
- Compare with VESA standards for compatibility

Common Vesa Size Standards
VESA sizes are the mounting hole patternson the back of monitors. They show the distance between holes in millimeters.
| VESA Size (mm) | Common Monitor Size | Use |
|---|---|---|
| 75 x 75 | 13″ to 24″ | Small monitors and TVs |
| 100 x 100 | 17″ to 27″ | Medium-sized monitors |
| 200 x 200 | 27″ to 32″ | Larger monitors |
| 400 x 400 | 32″ and above | Large TVs and monitors |
Check your monitor’s back for the hole pattern size. Use a ruler to measure the distance between holes in millimeters. This helps find the right mount or stand.
Choosing The Right Mount
Choosing the right mount starts with knowing the VESA sizeof your monitor. The VESA size is the distance between the mounting holes on the back of the monitor. It is usually measured in millimeters (mm).
Check the monitor’s manual or look for four screw holes in a square shape at the back. Measure the horizontal and vertical distances between these holes. Common VESA sizes include 75×75 mm and 100×100 mm.
Make sure the mount supports the same VESA pattern. Also, consider the monitor’s weight and size. The mount should hold the monitor firmly without bending or shaking.
- Check VESA pattern on your monitor
- Match mount’s VESA size with monitor’s
- Verify mount supports monitor’s weight
- Choose a mount type that fits your desk or wall
Tips To Avoid Measurement Errors
Measure the VESA size carefully to avoid mistakes. Use a ruler or tape measure that shows millimeters clearly. Measure the distance between the mounting holes from center to center. Check both horizontal and vertical distances to get the right size.
Keep the monitor flat on a table during measurement. This helps get accurate numbers. Avoid measuring at an angle. Double-check your measurements before buying a mount or stand.
- Do not guess the size; measure precisely.
- Use a straight ruler or tape for accuracy.
- Write down the numbers to avoid forgetting.
- Compare with the monitor manual if available.
Frequently Asked Questions
What Is Vesa Size On A Monitor?
VESA size refers to the distance between mounting holes on a monitor’s back. It ensures compatibility with monitor mounts and stands. Common sizes include 75x75mm and 100x100mm. Measuring it helps you choose the right wall mount or arm for your monitor.
How Do I Measure Vesa Size Accurately?
Use a ruler or tape measure to find the horizontal and vertical distance between mounting holes. Measure from the center of one hole to the center of the opposite hole. Record the width and height in millimeters for the VESA size.
Why Is Knowing Vesa Size Important?
Knowing your monitor’s VESA size helps you select compatible mounts or stands. It ensures secure and stable attachment. Without this, you risk buying incompatible accessories that won’t fit your monitor properly.
Can All Monitors Fit Standard Vesa Mounts?
Most modern monitors follow VESA standards, but some small or ultra-wide monitors may not. Check the manufacturer’s specs or look for mounting holes on the back. If no holes exist, the monitor likely doesn’t support VESA mounts.
Conclusion
Measuring your monitor’s VESA size is simple and important. It helps you find the right mount or stand. Just measure the distance between the mounting holes on the back. Use a ruler or tape measure for accuracy. Knowing this size saves time and avoids mistakes.
Now, you can set up your monitor safely and securely. Enjoy a clean and organized workspace with the right VESA mount. Keep these tips in mind for easy measuring next time.
