Start with compatibility
A monitor arm is useful only when its clamp, weight range, and mounting pattern match your equipment. Record the monitor weight without its original stand, screen size, VESA pattern, and desktop thickness before comparing products.
- Confirm that the desk edge can accept a clamp or grommet mount
- Check for a metal frame or cable tray beneath the mounting point
- Keep the monitor inside the manufacturer's published weight range
Measure the space the arm needs
Small desks often sit against a wall. Some arms swing behind the desk when the screen is pulled forward, so a compact desk can still require several inches of rear clearance. Measure the desk depth, wall gap, and desired eye position.
- Low-profile arms suit desks close to walls
- A tall pole can help stack screens without using extra depth
- Route cables with enough slack for the full movement range
Choose the right adjustment style
Gas-spring arms move frequently and easily, while pole-mounted arms can be simpler and more stable for a screen that rarely changes position. The better choice depends on behavior, not the number of advertised adjustments.
- Frequent sit-stand movement favors easy height adjustment
- A fixed work position may not justify a complex mechanism
- For two screens, compare total load and side-to-side width
