Reclaim desk space and fix your posture in one upgrade.
A good monitor arm frees the deepest part of your desk, lets you set exact eye-level height, and makes ultrawide and multi-monitor setups actually workable. It's one of the highest-impact upgrades per dollar in the whole desk setup world.
The catch: weight ratings, VESA compatibility, and clamp design vary wildly, and an under-specced arm slowly sags. Our guides sort arms by what they can genuinely hold — including heavy 34-inch and 49-inch ultrawides.
Monitor Arms
You don't need to spend Ergotron money to get your monitor off the desk. Four single arms under $50 — compared on the capacity, reach and warranty their makers actually publish.

Two screens, one mount — and one number the listings bury: several of these arms publish a combined weight cap lower than twice their own per-arm rating. Six dual mounts sorted by layout, load and warranty.

Ultrawides are heavy, and most arms quietly aren't rated for them. Five arms that hold 34- to 49-inch screens without sagging — matched to monitor weight.

Monitor Arms
Every monitor arm ships with a clamp and most also include a grommet base, and the box tells you nothing about which one your desk can actually take. Here is the decision, measured — including the desks where the honest answer is neither.

Check your monitor's weight without the stand, then leave headroom. Ultrawides commonly weigh 15–25 lbs — many popular arms top out below that.
Most monitors use 100×100 or 75×75 mm. Some thin or curved displays need an adapter plate — check before you buy.
Clamps need a few inches of clear underside desk lip; grommet mounts are more secure on thin or crowded desks.
Gas-spring arms adjust fluidly through the day; post-style arms are cheaper and stiffer but often more stable for heavy screens.
