UK What a VESA mount size means
VESA mount sizes are the hole patterns defined in the Flat Display Mounting Interface (FDMI) standard from the Video Electronics Standards Association, also called the VESA Mounting Interface Standard (MIS). A screen that follows it has four threaded holes in its back, arranged in a square or rectangle, so any bracket, arm or wall plate with the same pattern will fit it.
The size is written as the horizontal distance between hole centres, then the vertical distance, in millimetres. A VESA 100 screen has holes 100 mm apart each way (100 × 100). The first version, published in 1997, covered the 100 × 100 pattern and the smaller 75 × 75. In 2006 the standard was extended with larger patterns for heavier screens, so it now runs from tiny 50 × 20 plates to large squares for big displays.
The standard is the same in the UK, Europe and North America. Screw threads are metric everywhere; only the published weight limits are commonly quoted in pounds as well as kilograms.
VESA mount sizes chart
The standard groups the patterns into parts, each with a screw size and a maximum display weight. The table summarises them; the weights are the published limits for each part, rounded.
| VESA part | Hole pattern (mm) | Screws | Display weight up to | Typical use |
|---|---|---|---|---|
| MIS-B | 50 × 20 | M4 | About 2 kg (4.4 lb) | Very small screens and devices |
| MIS-C | 75 × 35 | M4 | About 4.5 kg (10 lb) | Small displays |
| MIS-D, 75 | 75 × 75 | M4 | About 8 kg (17.6 lb) | Small monitors and panel PCs |
| MIS-D, 100 | 100 × 100 | M4 | About 14 kg (30.8 lb) | Most desktop and industrial monitors |
| MIS-E | 200 × 100 | M4 | About 22.7 kg (50 lb) | Mid-size screens |
| MIS-F (M6) | 200 × 200 and up, in 100 mm steps | M6 | About 50 kg (110 lb) | Large monitors and TVs |
| MIS-F (M8) | 200 × 200 and up, in 100 mm steps | M8 | About 113.6 kg (250 lb) | Large-format displays |
Part F patterns are squares in steps of 100 mm, such as 300 × 300, 400 × 400 and 600 × 600, though many large TVs use non-square patterns such as 400 × 200 or 600 × 400. If a screen is heavier than its part allows, the next larger part should be used. A bracket rated for a pattern must also be rated for the weight of the screen plus anything fixed to it, such as a camera, a soundbar or a small PC.
How to measure your VESA pattern
If the datasheet does not state the pattern, it takes a minute to check with a ruler.
-
//
Measure horizontally first. Measure in millimetres from the centre of one hole to the centre of the hole beside it, then from that hole to the one above or below it. Write the result as width × height.
-
//
Check the screw size. Patterns up to 200 × 100 use M4 screws; larger ones use M6 or M8. The screen maker’s screws take priority over those supplied with a bracket.
-
//
Check the screw depth. Too long a screw can damage the housing; too short a screw strips the thread. Recessed or curved backs may need spacers.
-
//
Check the weight. Weigh the screen with its accessories and compare it with the bracket’s rating, not just the pattern.
VESA mounting on industrial monitors and panel PCs
Many industrial monitors and panel PCs carry a VESA pattern, typically 75 × 75 or 100 × 100 on screens up to around 24 inch (24″), with 200 × 200 and larger on big-format displays. That lets one screen be fixed to a desk arm, wall bracket, machine pole, cart or vehicle mount without a custom bracket. Our chassis and VESA mount panel PCs and chassis monitors are built for this, with a full enclosure on all sides so the whole system can hang in free air.
Industrial sites ask more of a mount than an office does. On machines and vehicles, vibration can loosen screws, so use thread locker or locking washers and check the fixings during maintenance. In washdown areas, the bracket and screws should be stainless steel so they do not rust before the screen does. Our white paper on mounting an industrial computer covers wall, DIN rail and machine mounting in more depth.
VESA vs panel, rack and open frame mounting
VESA is one of four common ways to fix an industrial screen. Each suits a different installation, and many models are offered in more than one style.
-
//
VESA mount. Fixed from the back on an arm, wall plate or pole. The screen stands in free air, so it can be moved or angled and serviced from behind.
-
//
Panel mount. Fitted into a cut-out in a cabinet door or machine panel and clamped from behind, with a gasket that seals the front. A good fit where the screen must sit flush and the cabinet protects the back. See our panel mount PCs.
-
//
Rack mount. Fixed into a 19 inch rack with front ears, with its height given in U, the rack unit. Suited to control rooms and equipment racks.
-
//
Open frame. No outer bezel, so the screen can be built into a kiosk, machine or custom enclosure. Our open frame panel PCs are made for OEM builds.
Quick answers on VESA mount sizes
VESA mounts: common questions
Are all VESA mounts 100 × 100?
No. 100 × 100 is the most common size for monitors, but 75 × 75 is widely used on smaller screens and 200 × 200 or larger on bigger ones.
Will a VESA 200 × 200 mount fit a 400 × 400 screen?
Only with an adapter plate. The plate must cover both patterns and be rated for the screen’s weight. Many larger brackets have slotted arms that already fit several patterns.
What does VESA stand for?
Video Electronics Standards Association. The same body also publishes the DisplayPort and DisplayHDR standards.
What does VESA compatible mean?
The screen has a standard hole pattern. It can take any bracket with the same pattern and a high enough weight rating.
Can I mount a screen that has no VESA holes?
Sometimes, with an adapter kit. Kits that clamp the screen’s edges exist for some models, but check the weight rating and that the clamps do not cover vents or controls.
We supply panel PCs and monitors with the VESA pattern, panel cut-out or rack ears the installation needs, and fit the mount, configure and test each system as standard before it ships.
