Quick answer: A monitor arm frees up desk space and lets you set your screen at eye level for better posture. Before buying, check four things: your monitor's VESA pattern (usually 75x75 or 100x100mm), its display-only weight fits the arm's capacity range with headroom (aim for about 1.5 times the weight), the mount type suits your desk (a clamp works for most, a grommet for a permanent or heavier install), and the mechanism — a gas-spring arm gives the smoothest adjustment. Ultrawide and heavy monitors need a heavy-duty arm, because a light one will sag over time. Get those right and an arm is one of the best desk upgrades you can make.
Monitor arm buying guide: short answer
- VESA pattern: confirm your monitor uses 75x75 or 100x100mm (or wider for ultrawides).
- Weight: use the display-only weight and buy ~1.5x headroom.
- Mount: clamp for most desks, grommet for a permanent or heavy install.
- Mechanism: gas spring for smooth, frequent adjustment.
- Heavy or ultrawide? Choose a heavy-duty arm so it won't sag.

Why use a monitor arm?
A monitor arm improves your posture and reclaims desk space by floating the screen off a stand. A typical stand occupies 8 to 10 inches of desk depth and locks the screen to one height, whereas an arm clamps to the desk edge and lets you set the top of the screen at or just below eye level, an arm's length away — the position that reduces neck and shoulder strain over long days. It also frees the space beneath for a keyboard, notes, or a laptop, makes cable routing cleaner, and enables arrangements a stand can't, like pushing the screen back, pulling it forward for detailed work, or rotating it to portrait. For a sit-stand desk, an arm keeps the screen correctly placed as you change posture. Our home office setup guide covers ergonomics more broadly.
1. Check VESA compatibility first
VESA is the standard pattern of four screw holes on the back of a monitor, and your arm must match it — usually 75x75 or 100x100mm. These two patterns cover the large majority of 24-to-32-inch monitors, while ultrawides (34 to 38 inches) often use 200x100mm and very large displays use wider patterns that may need an adapter plate. Before buying an arm, look at the back of your monitor to find the holes and confirm the pattern; if a plastic cover or the stand bracket hides them, they're usually underneath. Be aware that a few monitors use proprietary stands without a standard VESA mount and can't be converted, and that no adapter can bridge a fundamental pattern mismatch — so verify this first, before anything else.
2. Match the weight, not just the size
Choose an arm by your monitor's display-only weight — not its size — and add headroom so it holds position for years. Manufacturers list three weights: gross (with packaging), net (with stand), and display-only; only the display-only figure matters for an arm, since the stand comes off. Arms have a supported weight range, and a monitor that's too light drifts upward while one that's too heavy sags, so aim for roughly 1.5 times your monitor's real weight for stability. Screen size alone is misleading, because two 27-inch monitors can weigh very differently once you remove the stand. Curved and ultrawide panels deserve extra caution: the curve shifts mass forward and creates leverage that makes a standard arm sag even within its poundage rating, so they need a heavy-duty arm. You can usually find the display-only weight in the monitor's specs.
3. Clamp vs grommet mount
A C-clamp suits most desks and is easy and reversible; a grommet mount is more rigid and permanent for heavier setups. A clamp grips the back edge of your desk, so it needs a flat, accessible edge with about 2 inches of clearance behind the desk and a thickness within the clamp's range — it's the best choice for renters and anyone who rearranges often, since it leaves no marks. A grommet mount bolts through a hole in the desk (an existing cable hole or one you drill), sitting flush and feeling more planted, which helps with heavy or dual setups. Most arms include both fittings in the box. One important caution: thin, hollow-core desks can crack or compress under clamp pressure, and heavy arms should never be clamped directly to glass — use a reinforcement plate or a freestanding base for those surfaces.
4. Gas spring vs mechanical vs fixed
Gas-spring arms give the smoothest one-handed adjustment; mechanical-spring arms hold a set position well; fixed arms are the cheapest but don't float. A gas-spring (pneumatic) arm uses a pressurized cylinder to move smoothly across height, depth, and tilt and to hold wherever you leave it, which is ideal if you adjust often or use a sit-stand desk, and it's the better pick for heavier and ultrawide screens. A mechanical constant-force spring works similarly through a tension screw and suits a set-and-forget setup. A fixed or static arm is just a rigid pole with a VESA mount — positioned once at assembly. Don't assume "gas spring" means high quality, though: cheap cylinders can leak and droop within a year or two, so look for well-reviewed, higher-grade arms if you want lasting smoothness.
What adjustments do you need?
Decide which movements you'll actually use — height and tilt are essential, while swivel, portrait pivot, and extension add flexibility. An articulated arm with two or more joints lets you move the screen horizontally and vertically and adjust its angle without tools, which covers most needs; height and tilt matter most for setting a healthy eye-level position. Swivel helps you turn the screen toward a colleague, portrait pivot (rotation) is great for reading long documents and code, and extension or retraction lets you pull the screen close for detail work or push it back for space. Nice extras include integrated cable-management channels to hide wires and, on some arms, a built-in USB hub. Match the movements to your work rather than paying for features you won't touch.
Single, dual, or multi-monitor arm?
Pick the arm count for your setup now, but plan ahead — a single arm for one screen, a dual arm for two, and pole systems that expand for more. Most arms hold one monitor; a dual arm mounts two on a shared base and is the tidy way to align a pair at matching height, provided its per-screen capacity covers your heaviest monitor. If you might add a third screen later, some pole-based systems let you add arms without replacing everything. For a two-screen workspace, a dual arm makes the alignment and desk-space benefits especially worthwhile — see our dual monitor setup guide. Whichever count you choose, apply the same VESA, weight, and mount checks to each screen the arm will carry.

Quick recommendation
Buy a monitor arm by matching it to your specific monitor and desk, in that order. Confirm the VESA pattern (75x75 or 100x100mm for most screens), find your monitor's display-only weight and choose an arm rated for about 1.5 times that with room to spare, and pick a mount your desk can take — a clamp for most, a grommet for a permanent or heavy install, and a reinforcement plate for thin or glass surfaces. A gas-spring, articulated arm is the most versatile for everyday adjusting, and ultrawide or heavy panels want a heavy-duty version so they won't sag. Check the VESA and weight on your Kuycon monitor's product page, match it to an arm from the monitor arms collection, and you'll gain desk space and a healthier, more comfortable screen position.
Frequently asked questions
How do I choose a monitor arm?
Match the arm to your monitor's VESA pattern and display-only weight, then to your desk's mount type. Confirm the VESA holes (usually 75x75 or 100x100mm), pick an arm rated for about 1.5 times your monitor's real weight, and choose a clamp or grommet mount your desk supports. A gas-spring, articulated arm suits most people; heavy or ultrawide screens need a heavy-duty arm.
What VESA size do I need for a monitor arm?
Most monitors use 75x75 or 100x100mm, which nearly all arms support. Check the four screw holes on the back of your monitor to find the pattern; 100x100mm is standard for 24-to-32-inch displays and 75x75mm for smaller ones. Ultrawides may use 200x100mm and could need an adapter plate, so verify before buying.
How much weight should a monitor arm hold?
Around 1.5 times your monitor's display-only weight, so it holds position over time. Use the display-only figure (without the stand), not the gross or net weight. Arms have a supported range: too-light monitors drift up and too-heavy ones sag. Buying with headroom keeps the screen stable for years rather than months.
Is a clamp or grommet mount better?
A clamp is best for most desks; a grommet is more rigid and permanent. Clamps grip the desk edge, install without tools, and are reversible — ideal for renters. Grommets bolt through a hole for a cleaner, more planted feel, better for heavy or dual setups. Most arms include both, so match to your desk edge and how permanent you want it.
Are gas-spring monitor arms better?
Gas-spring arms are better for frequent adjustment; mechanical arms are better for set-and-forget. A gas spring moves smoothly with one hand and holds any position, which suits sit-stand desks and heavier screens. A mechanical spring works well if you rarely reposition. Quality varies, so choose a well-made arm — cheap gas cylinders can leak and droop within a year or two.
Will a monitor arm fit my monitor?
Yes, if your monitor has a standard VESA pattern and its weight is within the arm's range. Check the back for 75x75 or 100x100mm mounting holes and confirm the arm supports that pattern and your monitor's display-only weight. A few monitors use proprietary stands without VESA and can't be arm-mounted, so verify before buying.
Do monitor arms work with ultrawide monitors?
Yes, but ultrawides need a heavy-duty arm. Their width and curve shift weight forward, creating leverage that makes standard arms sag even within the rated weight. Look for a heavy-duty gas-spring arm with a stronger tilt joint and the correct VESA pattern (often 200x100mm), and consider a grommet mount for extra stability.
Can any monitor go on an arm?
Almost any modern monitor can, as long as it has a VESA mount. The vast majority of monitors use 75x75 or 100x100mm patterns and mount easily. The exceptions are some models with proprietary, non-VESA stands that can't be converted. Check the back of your screen for the four mounting holes before buying an arm.
Will a monitor arm damage my desk?
It can on thin, hollow-core, or glass desks if you're not careful. Clamp pressure can crack particleboard or compress hollow-core tops, so use the included pad or a reinforcement plate and avoid overtightening. Never clamp a heavy arm directly to glass. Solid wood and quality laminate handle clamp and grommet loads well.
Do I need a single or dual monitor arm?
Single for one screen, dual for two, and expandable pole systems for more. A dual arm mounts two monitors on one base and makes it easy to align them at matching height, as long as its per-screen capacity covers your heaviest display. If you may add screens later, a pole-based system lets you expand without replacing the whole arm.
Are monitor arms worth it?
Yes — an arm is one of the highest-value desk upgrades for comfort and space. It lets you position the screen at the right height and distance, reducing neck and shoulder strain, and frees the desk area a stand occupies. It also makes dual setups tidy and sit-stand desks practical. As long as it matches your monitor and desk, it pays off daily.
How do I know my monitor's weight?
Check the specifications for the display-only weight, or weigh it without the stand. The spec sheet or manual usually lists gross, net, and display-only weights — use the display-only figure for an arm. If it's not listed, remove the stand and weigh the panel on a scale. Using the wrong weight leads to an arm that sags or drifts.
