VESA Standards Explained: MIS-D, MIS-E & MIS-F

📅 Updated: 01/20/2026 ✍️ Editor: Julius E. ⏱️ Read time: approx. 9 min.

Are you looking for the right mount for your monitor or TV? Whether it's a desk mount for the home office or a sturdy TV wall mount for the living room – we break down the official VESA classifications (FDMI) technically so you know exactly what fits.

What does FDMI mean?

The official name of the standard is VESA FDMI (Flat Display Mounting Interface). The abbreviation VESA (Video Electronics Standards Association) refers to the organization that sets these standards. To avoid confusion caused by numbers alone, VESA divides mounts into letter classes (MIS = Mounting Interface Standard). This ensures that not only the hole spacing but also the load-bearing capacity of the screws is guaranteed.

Standard for PC & Office

VESA MIS-D (Small)

This is the most common standard for classic desk monitors and small TVs. Almost every desk monitor mount for the home office uses this format.

  • Hole pattern: Square
  • Dimensions: 75 x 75 mm or 100 x 100 mm
  • Screws: M4 thread
  • Typical Diagonal: 12 to 24 inches

Medium Size (Rare)

VESA MIS-E (Medium)

You will often find this standard on slightly larger, older monitors or medium-sized TV sets. It is not square, but rectangular. Pay close attention to the measurement here, as it is often confused with 100x100.

  • Hole pattern: Rectangular
  • Dimensions: 200 x 100 mm
  • Screws: M4 thread
  • Typical Diagonal: 23 to 31 inches

TV & Large Format

VESA MIS-F (Large)

For all large screens from 31 inches upwards. Here the spacing varies in 200mm increments. The screws are significantly thicker to securely hold the heavy weight of flat-screen TVs on the wall.

  • Hole pattern: Variable (square or rectangle)
  • Dimensions: 200x200 to 800x600 mm (in 200mm increments)
  • Screws: M6 or M8 thread
  • Typical Diagonal: > 31 inches

⚠️ Special Cases: Brands without VESA Standard

Many popular design monitors and all-in-one PCs have no VESA holes on the back. For these models, we develop specific adapters that click into the stand slot, creating a VESA mount (75x75).

Help: The plate doesn't fit into the recess?

Many gaming monitors have a recessed VESA mount. If your mounting plate is too large, use spacers (standoffs) and longer screws. These are usually included with our mounts.

Important before buying: Wall & Desk Condition

Not only the VESA standard counts, but also the surface. Whether it's a wall or a desk: The mount must sit securely.

1. Concrete & Solid Brick (Wall)

Here you can mount almost any bracket. Use the standard dowels supplied. These walls also carry heavy swivel arms without any problems.

2. Drywall / Plasterboard (Wall)

Cavity walls are the ultimate challenge. Normal dowels break out. You absolutely must find the studs or use special toggle bolts. We recommend flat mounts here.

3. Desk (Clamp & Grommet)

For a desk monitor mount, the thickness of the tabletop is decisive (mostly 1-8 cm).
Attention with cardboard honeycomb tables: Many cheap desks are hollow inside (honeycomb structure). A strong gas spring clamp can crush the top. Be sure to use a reinforcement plate or rely on solid wood/chipboard.

Installation Tools Checklist:
  • ✏️ Pencil for marking
  • 📏 Tape measure & spirit level
  • drill Drill (for wall)
  • 🔧 Screwdriver & wrench
  • 👀 Second person (for TV > 40 inches)

Tip: Many of our mounts have an integrated mini spirit level.

What about MIS-A, B and C?

Theoretically, these standards exist for very small displays (handhelds, tablets) under 12 inches, but play practically no role in the world of monitor and TV mounts. You will almost always need MIS-D or higher.

All VESA classes compared directly

Use this table to assign your measured hole spacing to the correct VESA designation.

Designation Hole Spacing (mm) Screw Screen Size (approx.)
VESA MIS-D 75 75 x 75 M4 12" - 23"
VESA MIS-D 100 100 x 100 M4 12" - 24"
VESA MIS-E 200 x 100 M4 23" - 31"
VESA MIS-F 200 200 x 200 M6 from 31"
VESA MIS-F 400 400 x 400, 400 x 200 M6 / M8 from 31"
VESA MIS-F 600+ 600 x 400, 800 x 600 M8 Large TVs

Frequently Asked Questions about VESA Standards

Do I need to know the exact designation (MIS-D)?+
Not necessarily. Retailers usually use the millimeter specifications (e.g., "VESA 100"). However, the MIS designation helps you to assign the correct screw size (M4 vs. M6) and weight class more quickly.
How do I measure the VESA distance correctly?+
Measure the distance between the four threaded holes on the back of your screen: First horizontally, then vertically in millimeters. A distance of 200mm width and 100mm height corresponds to VESA 200x100 (MIS-E).
Which screws do I need (M4, M6, M8)?+
That depends on the MIS class: MIS-D (up to 24 inches) almost always uses M4. MIS-E also mostly uses M4. From MIS-F (large TVs), thicker M6 or M8 screws are used.
What if I have MIS-F hole spacing but M4 screws?+
This is a special case. There are monitors that do not adhere exactly to the standard. In this case, the hole spacing is decisive. Screws are usually included with our mounts in various sizes or can be bought at a hardware store. It is important that the backplate of the mount fits.
My monitor has no holes - what now?+
For models without a VESA standard (e.g., many Apple iMacs or design monitors), there are special VESA adapters. These create an artificial VESA mount (usually MIS-D 75 or 100) so you can still use a monitor arm.
Are there adapters from MIS-D to MIS-F?+
Yes, there are VESA extension plates. You can use these to adapt a small mount (e.g., 100x100) to a large TV (200x200).
But be careful: Absolutely pay attention to the load capacity of the small mount! A large TV is often too heavy for a small monitor arm.
What is more important: inch size or weight?+
The weight is critical for safety. The inch size rather indicates whether the swivel range fits. A 32-inch monitor can theoretically fit on a MIS-D mount if it is light enough, but with MIS-F TVs, weight is often the limiting factor.
Can I use VESA 75 on a VESA 100 mount?+
Yes, almost all modern mounts in the MIS-D category have a so-called combo plate with holes for both standards (75x75 and 100x100). You simply use the inner holes.
What do I need to consider with curved monitors?+
Due to the curvature, the center of gravity shifts forward (leverage effect). When in doubt, choose a mount with a higher load capacity. You also often need spacers and longer screws so that the VESA plate does not "wobble" on the curved housing.
How long should the VESA screws be?+
Screws that are too long can damage the electronics inside! Screw them in carefully. If you feel resistance before the plate is tight: Stop! Use washers or shorter screws. Most manuals state the maximum penetration depth.
