Check your monitor's weight and VESA pattern first, then choose an arm whose weight range includes it. Gas spring arms move smoothly and suit frequent adjustment; mechanical arms are cheaper and fixed. Confirm your desk can take a clamp or grommet mount and is thick and sturdy enough. Arms free up desk space and make it easy to keep the screen at eye level.
A monitor arm puts your screen exactly where your eyes want it and frees up space below.
Check your monitor
| Check | Where to find it |
|---|---|
| Weight without stand | Spec sheet |
| VESA pattern | Back of the monitor or manual |
| Screen size and curve | Spec sheet |
Choose the arm
- Weight range: the monitor must sit within it, not at the extreme ends.
- Gas spring vs mechanical: gas springs move easily and hold position; mechanical arms are cheaper but stiffer.
- Single, dual or stacked setups for multiple screens.
- Reach and height so the top of the screen sits at eye level.
Mounting
- Clamp: attaches to the desk edge; check maximum desk thickness.
- Grommet: goes through a hole in the desk.
- Desk strength: thin glass or particle board may need a reinforcement plate.
Finish the setup
Route cables through the arm’s channels and leave slack for movement on a standing desk.

Common questions
What is VESA?
A standard pattern of mounting holes on the back of monitors, such as 75 x 75 mm or 100 x 100 mm.
My monitor has no VESA holes. What can I do?
Some brands sell adapters for specific models. Check before buying an arm.
Can I use a monitor arm on a standing desk?
Yes. Make sure cables have enough slack and the desk's weight capacity includes the arm and monitor.
Do ultrawide monitors need special arms?
Often. They can be heavy and wide; choose an arm rated for the weight and screen size.
