Best Monitor Arms (2026): Single, Dual & Ultrawide
A monitor arm lets you put the top of your screen at eye level, pull it closer or push it away, and free up desk space. The most important check is fit: your monitor's weight has to fall within the arm's rated range, and its mounting holes have to match. Here are five arms for different setups.

How to choose
Weigh your monitor without its stand
Look up the monitor's weight without the stand on its spec sheet. It must fall inside the arm's range: gas-spring arms have a minimum as well as a maximum, so a very light screen can drift up just as a heavy one sags.
Check the VESA pattern
Most arms fit 75 × 75 mm and 100 × 100 mm hole patterns. Some monitors (including certain Apple and curved models) need an adapter, so check before you order.
Know your target height
Our calculator estimates your seated eye height. Make sure the arm can lift the top of your screen to that height from your desk surface.
Check your desk edge
Clamp mounts need clearance behind the desk and a solid edge. Thin, glass or particleboard desks may need a reinforcement plate. A grommet mount uses an existing cable hole instead.
Curved and ultrawide screens need more
Large curved monitors are heavy and deep, which reduces an arm's effective capacity. Choose an arm rated for the size and weight, like the Ergotron HX.

The shortlist
Best overall single arm
1. Ergotron LX Desk Mount
The LX is the monitor arm most often recommended for good reason: smooth movement, a long reach and a long warranty from a company that specializes in mounts.
What we like
- Smooth, stable movement
- Long reach and good lift range
- Clamp and grommet mounts included
Trade-offs
- Costs more than budget arms
- Not for heavy ultrawide screens
Skip it if: Your monitor is over 25 lb or a large curved ultrawide.

2. HUANUO FlowLift Single Monitor Arm
A gas-spring arm at a fraction of the Ergotron's price (sold as FlowLift, model HNSS6). It covers most 13–32 inch monitors and is a popular first arm.
What we like
- Low price
- Gas-spring height adjustment
- Clamp and grommet options
Trade-offs
- Heavier 32 in curved monitors can be borderline
- Less refined than Ergotron
Skip it if: Your monitor is near 20 lb or deeply curved.

3. Ergotron HX Desk Mount
Built for big, heavy screens, including 49-inch super-ultrawides. It's the arm to look at if you own one of the monitors in our ultrawide monitor guide.
What we like
- Handles heavy ultrawides
- Ergotron build quality
- Tilt and swivel for large screens
Trade-offs
- Too strong for light monitors (minimum weight)
- Very deep curved screens may need Ergotron's heavy-duty pivot
Skip it if: Your monitor weighs under 20 lb.

4. Ergotron LX Dual Monitor Arm
Two LX-style arms on one pole for a pair of matching monitors. It frees up the whole back of the desk.
What we like
- One clamp for two screens
- Ergotron quality and warranty
- Easy side-by-side alignment
Trade-offs
- Pricey
- Best with two similar monitors
Skip it if: Your two monitors are very different sizes or weights.

5. VIVO Single Monitor Desk Mount (STAND-V001)
A simple pole mount with a tilting, swiveling arm. It isn't as quick to move as a gas-spring arm, but it's an inexpensive way to raise a screen and clear desk space.
What we like
- Very low price
- Simple and sturdy
- Clamp or grommet base
Trade-offs
- Height set with a collar, not one-handed
- Specs vary between VIVO variants
Skip it if: You move your screen around often during the day.

How high should my monitor be?
The top of the screen should sit at or slightly below eye level, about an arm's length away. Our calculator estimates your seated eye height from your body height.
Will a monitor arm damage my desk?
On a solid desk, no. Thin, glass or particleboard desktops can crack or dent under a clamp; a steel reinforcement plate spreads the load.
My monitor has no VESA holes. Can I still use an arm?
Often yes, with a VESA adapter bracket made for your monitor size. Check that the adapter's weight rating covers your monitor.
Do monitor arms work on standing desks?
Yes. Leave enough cable slack for the full height range, and count the monitor and arm weight toward your desk's lift capacity.
