How to Measure Monitor Stand Holes Accurately
So, you’ve got a shiny new monitor arm or desk mount and you’re ready to get that screen off your desk. Great idea. But then you look at the mounting plate, see a pattern of holes, and your brain immediately goes, ‘Wait, what holes? What size? What spacing?’ It’s a legitimate panic, especially after I spent a solid $150 on a gas-spring arm that looked amazing but, surprise, didn’t fit the VESA holes on my old-school Dell monitor because I hadn’t bothered to check the damned pattern first.
Learning how to measure monitor stand holes isn’t rocket science, but it is fiddly. It’s the kind of thing where if you get it wrong, you’re not just annoyed; you’re potentially looking at returning parts, waiting for replacements, and generally feeling like an idiot.
This isn’t about some abstract theory. This is about real-world application when you just want your monitor to sit where you want it without wobbling or, you know, falling off.
What You Need to Know About Monitor Mount Hole Patterns
Alright, let’s cut to the chase. Most modern monitors and TVs adhere to a standard called VESA Mounting Interface Standard (MIS). This means there are specific hole patterns on the back of your display designed for mounting. You’ll typically find these patterns in a square or rectangular arrangement. The key measurements are the horizontal and vertical distances between the centers of these holes, usually measured in millimeters (mm).
Common VESA patterns include 75x75mm, 100x100mm, 200x100mm, 200x200mm, and larger ones for TVs like 400x400mm. Your monitor mount will also specify the VESA patterns it supports. If your monitor and mount’s VESA specs align, you’re golden. If not, well, that’s where the measuring comes in.
This is where a lot of people get tripped up. They see a mount that says it supports ‘up to 100x100mm’ and assume it’ll fit their 100x100mm monitor. Sometimes it does, but sometimes the mount has additional holes or larger slots to accommodate slightly off-spec or older patterns. Honestly, if the official VESA designation from your monitor’s manual or the manufacturer’s website matches the mount’s specs, you’re usually good to go. But if you’re in doubt, or dealing with an older piece of tech, grabbing a ruler is the smartest move.
The Actual Process: How to Measure Monitor Stand Holes
Don’t overcomplicate this. Get yourself a decent tape measure. A metal one is best because it’s rigid and won’t flex, but a flexible tailor’s tape measure can work in a pinch if you hold it really taut. Make sure it has millimeter markings, not just inches. You’re going to be measuring the distance between the centers of adjacent screw holes. Usually, this means measuring from the center of one hole directly across to the center of the next hole, either horizontally or vertically.
Step 1: Locate the VESA holes. They’re typically found in a square or rectangular pattern on the back of your monitor, often behind a plastic cover or near the base. Sometimes, the holes are just there, exposed. They are threaded, meaning they have little ridges inside for the screws to grip. (See Also: How To Monitor At Risk Students )
Step 2: Measure the horizontal distance. Place the ‘0’ mark of your tape measure at the center of one screw hole on the left. Stretch the tape measure straight across to the center of the screw hole directly to its right. Read the measurement in millimeters. Don’t measure from edge to edge of the holes; aim for the dead center.
Step 3: Measure the vertical distance. Do the same thing, but measure from the center of an upper screw hole straight down to the center of the hole directly below it. Again, keep the tape measure perfectly straight.
Step 4: Note the pattern. You should end up with two numbers, like 100mm x 100mm, or 75mm x 75mm, or even 200mm x 100mm. This is your monitor’s VESA pattern.
Here’s a little tip: If you’re using a flexible tape measure, try to align the ‘0’ with the very center of the hole and then gently curve the tape to the center of the next hole. It sounds fiddly, and it is. A rigid ruler or tape measure, held against a straight edge between the centers, is much easier. I once spent about twenty minutes trying to get a precise reading with a flimsy tape measure, only to realize I was off by 5mm because the tape had bowed. Frustrating doesn’t even begin to cover it.
When the Vesa Standard Isn’t the Whole Story
Here’s a contrarian take for you: Everyone talks about VESA standards, and yeah, they’re important. But sometimes, the *actual hole size* and the *depth of the threading* matter more than the spacing alone. Some monitor arms come with a whole assortment of screws, and they’re not just there to look pretty. They cater to different thread pitches and lengths needed for various monitor backs. I’ve had mounts where the 100×100 VESA pattern was correct, but the included M4 screws were too short to properly engage the threads in the monitor’s casing. The monitor felt loose, like it was just hanging on by a prayer. That’s not a good feeling.
So, while you’re measuring the spacing, also have a quick look at the screw holes themselves. Are they deeply threaded? Do they look standard? If you’re buying a mount and your monitor’s VESA pattern matches, but you’re still unsure, check the mount’s product page or manual for details on included screw sizes (M4, M5, M6 are common) and lengths. It’s like buying a car part; you need the right bolt size and thread pitch, not just something that vaguely fits the hole.
As a general rule, the American National Standards Institute (ANSI) oversees many of these hardware specifications, and while VESA focuses on the mounting interface itself, the screw dimensions are often implied by the display manufacturer’s design. So, it’s a bit of a layered approach to compatibility. (See Also: How To Monitor Cheators Secound Apps )
Common Pitfalls and How to Avoid Them
One of the biggest mistakes people make is assuming all holes are the same size. They are not. You need to know whether your monitor uses M4, M5, or M6 screws. M4 is typically for smaller monitors (75x75mm VESA), M5 for 100x100mm, and M6 for larger displays or some TV mounts (which often use 200x100mm or larger). The mount should come with a selection, but knowing this beforehand helps. I once bought a mount that only came with M4 screws, and my 100×100 monitor needed M5s. So I had to make a special trip to the hardware store, spending an extra $12 and wasting a good hour of my Saturday morning. Annoying.
Another issue? The monitor itself might have a recessed area around the VESA holes, or a plastic shroud that obstructs some mounts. Always check the depth of the mounting bracket and the clearance around the holes. Some mounts are flush, others have a bit of a standoff. If the shroud is too bulky, it might prevent the mount from sitting flush against the back of the monitor, creating instability.
I’ve seen people try to force screws that are too large or too short, stripping the threads in the monitor or just not getting a secure connection. This is like trying to jam a square peg into a round hole – it just doesn’t work and it damages both the peg and the hole. Always use the correct screw, and if the included ones don’t seem right, consult your monitor’s manual or the mount manufacturer’s support. Seven out of ten times, the included screws will have the right thread pitch and length if you sort them correctly.
When you’re measuring, don’t just eyeball it. The difference between, say, 95mm and 100mm might seem small, but it’s enough to make a mount incompatible. Use a ruler or tape measure with clear millimeter markings. Seriously, get a decent tool. The cheap plastic ones you get in some DIY kits are often inaccurate. For this, a sturdy metal tape measure is your best friend.
It’s also worth checking if the mount’s mounting plate has enough adjustability or slots to accommodate minor variations. Some higher-end mounts are more forgiving than basic ones. But don’t rely on that forgiveness; measure first.
How to Measure Monitor Stand Holes vs. Mount Compatibility
Think of it like fitting a custom kitchen countertop. You wouldn’t just measure the general area; you’d measure the exact cabinet dimensions, account for overhang, and check for any awkward angles. Measuring monitor stand holes is precisely that level of detail. The VESA designation is the general area, but the actual hole-to-hole measurement is the precise cabinet dimension.
When you’re looking at a monitor mount, it will list the VESA patterns it supports. For example, it might say ‘Supports VESA 75x75mm, 100x100mm, and 200x100mm’. If your monitor’s measured pattern is 100x100mm, and the mount supports it, you’re in business. If your monitor is 100x100mm and the mount *only* supports 75x75mm, it won’t work. Conversely, if the mount supports 100x100mm and larger, and your monitor is 100x100mm, it should fit. The key is that your monitor’s pattern must be *listed* as supported by the mount.

Some mounts have elongated slots instead of just holes. This is usually to accommodate slight variations or for easier alignment when you can’t get the angle just right. But the *center-to-center* measurement is still the primary spec. The slot just gives you a little more wiggle room if your measurement is slightly off or if the holes on your monitor aren’t perfectly aligned (which is rare but not impossible).
Don’t forget to check the weight capacity of the mount too. This is a separate spec from the VESA pattern, but equally important. A mount might have the right holes but be too flimsy for your heavy ultrawide monitor.

What If My Monitor’s Vesa Pattern Is Not Standard?
This is less common with modern displays but can happen with older equipment or specialized monitors. If your VESA pattern isn’t a common one (like 75×75, 100×100, 200×100, etc.), you might need to look for monitor arms or wall mounts that offer a wider range of adjustability or have a ‘universal’ mounting plate. Universal plates often have a grid of holes that can be adapted to various patterns. Always double-check the mount’s specifications to see if it explicitly lists compatibility with your specific, non-standard pattern, or if it’s designed for wide adaptability.
Can I Use a Wall Mount If I Don’t Know the Vesa Holes?
You absolutely need to know your VESA hole measurements before buying a wall mount. Wall mounts, like desk mounts, rely on the VESA standard for secure attachment. If you don’t measure and the mount doesn’t fit, you risk the TV or monitor not being securely attached, which is a massive safety hazard. It’s the same principle as attaching any heavy object to a wall; you need the correct interface. Grab a tape measure and find those holes.
What Tools Do I Need to Measure Monitor Stand Holes?
The essential tools are a tape measure or a ruler with millimeter markings. A metal tape measure is ideal for rigidity and accuracy. You might also want a small flashlight to get a clear view of the hole centers and the markings on your measuring tool, especially if the monitor is already in place. A pencil or marker can be helpful for marking the center points if the holes are large or recessed, but be careful not to scratch your monitor.
Conclusion
So, that’s the lowdown on how to measure monitor stand holes. It boils down to a simple measurement using a tape measure, but getting it right saves you a mountain of hassle. Don’t just guess; take the two minutes to get the millimeter measurements.
If you’re buying a new mount, always compare your monitor’s VESA specification (which you just learned how to measure!) against the mount’s supported patterns. It’s the first and most important compatibility check.
Honestly, the frustration of buying the wrong mount because you skipped this step is something I wouldn’t wish on anyone. Make sure you know how to measure monitor stand holes correctly before you click ‘buy’.
