Monitor Arm Buying Guide: VESA, Weight Capacity and Desk Clamps for Gamers

Your monitor's stand takes up space, often only tilts, and usually sits too low or too far back. A monitor arm fixes both: the screen floats above the desk, you set height, distance and angle freely, and you gain room underneath for your keyboard and a large mouse pad. To make sure the arm actually holds up, there are a few values you need to check before buying. In this buying guide, you'll learn what matters for VESA, weight capacity, desk mounting and the mechanism, and how to position your monitor ergonomically. At the end, you'll find five example models for different setups.

Transparency: We have not tested these monitor arms ourselves. Specs come from the manufacturers (Ergotron, HUANUO, Invision) and from verified amazon.de product pages (as of October 2026). We deliberately omit prices because they change constantly.

The most important criteria at a glance

1. VESA pattern: 75 × 75 or 100 × 100 mm

Monitor arms attach to the four threaded holes on the back of your monitor. The VESA FDMI standard defines that pattern. For monitors, Part D (MIS-D) is what counts: 100 × 100 mm is the preferred pattern for displays up to 14 kg, while 75 × 75 mm is intended for smaller displays that typically weigh less than 8 kg. Almost all desk-mounted monitor arms support both.

How to check your monitor:

• Measure the hole pattern or look for "VESA 100" or "VESA 75" in the spec sheet.
• Recessed mount? If the holes sit in a recess, you need longer screws and spacers. Amazon Basics explicitly advises choosing the screw length based on the mounting depth of your monitor.
• No VESA? Then a regular monitor arm won't fit directly – plan for that before you buy.

2. Weight capacity: maximum and minimum

Every arm has a weight range, for example 2–9 kg or 1.8–10 kg. Both limits matter: if the monitor is too heavy, it sags. If it's too light, the spring pushes it up. What counts is the weight of the monitor without its stand – many manufacturers list both values in the spec sheet.

The screen size is only a guideline. Ergotron's LX Pro spec sheet even states that the listed screen size may be exceeded as long as the weight stays within the capacity. With large curved and ultrawide monitors, checking the weight is especially important. For choosing the monitor itself, see our gaming monitor buying guide.

3. Desk mounting: clamp or grommet

Most arms attach to the edge of the desk with a C-clamp. The alternative is a grommet mount through a hole in the desktop, such as an existing cable pass-through. Check before buying:

• Desk thickness: Each manufacturer lists a range, for example 1.0–10.8 cm for the Amazon Basics arms or 1–6 cm for the Ergotron LX Pro clamp.
• Space behind the desk: Even if your desk is right against the wall, the clamp still needs room at the edge.
• Desk construction: ARCTIC recommends adding a reinforcement plate for desktops with a honeycomb structure or hollow chambers so the clamp doesn't damage the panel.
• What's in the box: Not every arm includes both options. For the Ergotron LX Pro, for example, the grommet mount is sold separately.

4. Mechanism: gas spring or spring system

To let you move the monitor with one hand, a spring counterbalances its weight. Many arms use a gas spring, such as the HUANUO HNSS6 and the Invision MX450. Ergotron calls its system Constant Force. Either way, the tension has to match your monitor. HUANUO, for example, points out that the tension is set low at the factory and has to be increased after mounting. Always adjust the tension once the monitor is already attached to the arm.

5. Range of motion and extras

Typical specs are tilt (up/down), swivel (left/right) and rotation (turning to portrait). A 360° rotation is handy if you want to use a second monitor in portrait mode for chat, Discord or a stream overlay. Other extras: cable management inside the arm, a quick-release for the monitor, a rotation stop that keeps the monitor from hitting the wall, or an indicator for the tension setting.

6. One or two monitors

For two monitors, there are dual arms sharing one pole. Make sure each arm has enough capacity on its own and can be adjusted independently. Alternatively, you can mount two single arms if the desk edge has enough room.

Positioning your monitor: height and distance

A monitor arm only helps if you set it up properly. The German Social Accident Insurance (DGUV) and the US Occupational Safety and Health Administration (OSHA) give similar recommendations:

• Height: According to the DGUV, the top line on the screen should never be above the horizontal line of sight. OSHA recommends placing the top of the monitor at or slightly below eye level; the center of the screen is then normally 15 to 20 degrees below horizontal eye level.
• Distance: The DGUV names at least 50 cm, with 50 to 65 cm having proven effective for typical reading tasks. OSHA generally names 50 to 100 cm.
• Alignment: The monitor sits directly in front of you. OSHA advises keeping it no more than 35 degrees to the left or right.
• Tilt: Tilt the screen so you look at it as close to perpendicular as possible. According to OSHA, 10 to 20 degrees is usually enough.

Your seating position matters just as much. Set up your chair first, then the monitor – tips in our gaming chair buying guide. You can use the freed-up desk space for a larger mouse pad, see the gaming mouse pad buying guide.

Checklist before you buy

1. Does my monitor have VESA 75 or 100 – and is the mount recessed?
2. How much does it weigh without the stand – is that within the arm's range?
3. How thick is my desktop, and is it solid or hollow?
4. Clamp or grommet – and are both included?
5. One or two monitors, landscape or portrait too?

FAQ

Does every monitor fit a monitor arm?

No. The monitor needs a VESA hole pattern, usually 75 × 75 or 100 × 100 mm for desk arms. Its weight without the stand also has to be within the arm's capacity range.

Why does my monitor drift up or down on its own?

The spring tension doesn't match the weight. Increase the tension if it sags and reduce it if it creeps up. If the monitor is below the minimum weight, this often can't be compensated.

Will a monitor arm work on any desk?

Only if the desk thickness matches the arm and the desktop is sturdy. For desktops with a honeycomb structure or hollow chambers, ARCTIC recommends a reinforcement plate.

How high should the monitor be?

According to the DGUV, the top line on the screen should not be above eye level. OSHA recommends the top of the monitor at or slightly below eye level.

Can I put an ultrawide monitor on an arm?

Yes, if VESA and weight fit. Ergotron notes that the listed screen size may be exceeded as long as the weight stays within the limit. For heavy models, there are arms with a higher capacity such as the Invision MX450.
