VESA Mount Compatibility Guide: 75x75 vs 100x100 Explained
VESA Mount Compatibility Guide: 75x75 vs 100x100 Explained
Key Takeaways
- VESA defines the standard hole pattern on the back of monitors. The two most common sizes are 75x75mm and 100x100mm.
- Most monitors 24 inches and larger use 100x100mm VESA, while smaller monitors often use 75x75mm.
- Checking your monitor's VESA pattern before buying a stand ensures compatibility and avoids returns.
- Low-profile, high-weight-capacity stands from Wearson support both VESA sizes and fit monitors up to 30 inches.
What Is VESA and Why Does It Matter for Monitor Stands?
VESA stands for the Video Electronics Standards Association, the organization that created the Flat Display Mounting Interface Standard (FDMI) in 1997. This standard defines the pattern of mounting holes on the back of flat-panel monitors, TVs, and displays. In 2026, virtually every monitor stand and arm on the market uses VESA compatibility as the primary compatibility check, making it the single most important factor when choosing a stand.
What Are the Standard VESA Mounting Patterns?
The two most common VESA patterns for computer monitors are 75x75mm and 100x100mm. The numbers refer to the horizontal and vertical distance between the four screw holes, measured in millimeters. A 75x75mm pattern has holes spaced 75mm apart in a square, while a 100x100mm pattern has 100mm spacing. Some larger monitors and TVs use patterns like 200x200mm or 400x400mm, but these are rare for standard home office displays.
| VESA Pattern | Hole Spacing | Common Monitor Sizes | Typical Weight Capacity |
|---|---|---|---|
| 75x75mm | 75mm apart | 10 - 24 inches | Up to 10 kg (22 lbs) |
| 100x100mm | 100mm apart | 17 - 30 inches | Up to 10 kg (22 lbs) |
| 200x200mm | 200mm apart | 32 inches and larger | Varies |
How Do I Check Which VESA Pattern My Monitor Uses?
Checking your monitor's VESA pattern takes less than a minute. Look at the back of your monitor for four screw holes arranged in a square. If you see two sets of holes (one smaller square inside a larger one), your monitor supports both 75x75mm and 100x100mm. Measure the distance between opposite holes if you are unsure. If the monitor is still in its box, check the specifications sheet or search online for your monitor model number followed by "VESA."
Most major brands, including Dell, LG, Samsung, Acer, and HP, list VESA compatibility in their product specifications. For monitors that do not have VESA holes, an adapter plate may be available, though these are not guaranteed for every model.
Does Every Monitor Stand Support Both VESA Sizes?
Not all stands support both sizes. Many budget-friendly stands support only one pattern. However, most mid-range and premium stands include both 75x75mm and 100x100mm compatibility, either through a single mounting plate with multiple hole positions or through interchangeable brackets. Wearson's monitor stands, for example, support both 75x75mm and 100x100mm VESA patterns across all models, making them compatible with the vast majority of home office monitors.
What Happens If My Monitor Does Not Have VESA Holes?
Some monitors, particularly ultra-slim or budget models, do not include VESA mounting holes. In this case, you have a few options. A VESA adapter kit can add mounting points to the monitor, though these are not universally compatible. Alternatively, a monitor riser or tray that the monitor sits on top of can provide ergonomic height without requiring VESA attachment. If you plan to use a monitor arm or a secure stand, check for VESA compatibility before purchasing.
How Does VESA Compatibility Affect Monitor Orientation?
VESA compatibility is the same regardless of whether you use your monitor in landscape or portrait mode. The mounting holes stay in the same position, and the stand or arm holds the monitor securely in either orientation. However, the center of gravity shifts when the monitor is rotated, which is why a low-profile stand with high weight capacity is recommended for portrait mode, especially with monitors 24 inches or larger.
Frequently Asked Questions
Can I use a 100x100mm stand on a 75x75mm monitor?
No, the hole spacing does not match. If your stand has a fixed plate with only 100x100mm holes, it will not align with a 75x75mm monitor. However, most quality stands include both patterns on the same bracket, so check your stand's specifications before assuming it supports only one size.
Do all monitors have VESA mounting holes?
No. While most standard monitors from Dell, LG, Samsung, and similar brands include VESA holes, some ultra-slim or budget models omit them. Always check the back of your monitor or the product specifications before buying a stand. If your monitor lacks VESA holes, an adapter may work, but it is not guaranteed.
Is VESA the same for monitor stands and TV mounts?
Yes, the VESA standard is universal across both monitors and TVs. The hole patterns are identical. However, TV mounts are designed for heavier loads and larger patterns (200x200mm and up), while monitor stands use smaller patterns. A TV mount will work with a monitor, but it may be bulkier than needed.
What screws do I need for VESA mounting?
VESA-compatible stands include the required screws in the package. Monitor manufacturers use different screw sizes (typically M4, M6, or M8), but most stands ship with a variety of screw lengths and types to fit common monitors. Wearson stands include both KM4 and KM3 screws with a screwdriver, covering most standard VESA installations.
Does VESA size affect weight capacity?
Not directly. The weight capacity of a monitor stand is determined by its construction materials and design, not by the VESA pattern size. A well-built 75x75mm stand can hold more weight than a poorly built 100x100mm stand. Always check the stand's rated weight capacity rather than assuming it is determined by the VESA pattern.
Conclusion
VESA compatibility is the foundation of any monitor stand purchase. Knowing whether your monitor uses a 75x75mm or 100x100mm pattern takes just a moment to check and ensures you buy a stand that fits. Most home office monitors fall into the 100x100mm category, but many support both patterns. A stand that covers both sizes, offers adequate weight capacity, and fits your desk space will serve you well through multiple monitor upgrades.
- Check your monitor's VESA pattern before buying a stand.
- Choose a stand that supports both 75x75mm and 100x100mm for maximum flexibility.
- Verify the stand's weight capacity matches your monitor's weight with a safety margin.
- Consider a low-profile stand for better stability with larger monitors.
- All necessary mounting hardware is typically included with the stand.
