Monitor Arm vs Monitor Stand: Which Should You Buy?

A monitor arm is the better choice if you switch between sitting and standing, share the desk, work on a shallow desktop or need to fine-tune height, depth and tilt often. A monitor stand or riser is the better choice if your monitor has no VESA mounting holes, your desk cannot take a clamp or grommet, or you set the screen once and rarely touch it. Both can put the screen where ergonomics guidance wants it: about an arm’s length away, with the top of the screen at or slightly below eye level. This comparison is research-based and draws on OSHA, CCOHS and university ergonomics programs; it is not a review of any specific product.

This is general workstation setup information, not medical advice. If you have neck, shoulder or eye discomfort, ask a qualified health professional about your setup.

What Is the Difference?

• A monitor arm attaches to the desk, usually with a C-clamp at the desk edge or a bolt through a grommet hole, and holds the monitor by the VESA mounting holes on its back. Jointed arms let you move the screen up, down, forward, back, and often tilt, swivel and rotate it.
• A monitor stand sits on the desktop. This covers the stand that ships with the monitor (some adjust in height, others only tilt) and separate risers or platforms that lift the screen to a fixed height, often with storage space underneath.

Where the Screen Should End Up

Whichever you choose, the goal is the same position. OSHA’s computer workstation eTool gives these targets:

• A viewing distance of 20 to 40 inches, and at least 20 inches.
• The top line of the screen at or below eye level, with the center of the screen normally 15 to 20 degrees below horizontal eye level.
• A screen tilted so it is perpendicular to your line of sight, usually tilted back no more than 10 to 20 degrees.

CCOHS puts it more simply: an arm’s length is usually a good estimate of how far the monitor should be, and the top of the screen should not be higher than your eyes. OSHA adds that bifocal users typically look through the bottom of their lenses and may need the monitor lower than these recommendations. Our guide to standing desk height shows how to measure your own eye height seated and standing.

Side-by-Side Comparison

What Ergonomics Programs Say

Duke University’s workstation standards, which are based on the ANSI/HFES 100-2007 standard, say monitors should be as adjustable as possible in height, depth and angle, and list two ways to get there: a monitor with built-in height adjustment or a monitor arm. The same document says monitor height can be adjusted with “adjustable monitors, monitor arms, risers, or platforms if needed,” and that monitors should sit directly on the work surface or a monitor arm, not on the computer or a docking station. OSHA makes the same point about stacking: placing the monitor on top of the computer case generally raises it too high for all but the tallest users.

The University of Washington’s furniture guidance adds a useful caution in the other direction. It notes that a riser holding the monitor can be moved to any preferred position on the table, while an articulating arm mounted at a fixed spot on the desk may keep the monitor from being placed in the preferred location in front of the user. In other words, an arm only helps if it is mounted where it can reach the right spot.

When a Monitor Arm Is the Right Call

• You alternate between sitting and standing. Your eye height changes between postures, so being able to move the screen quickly matters. Colorado State University’s ergonomics program reminds sit-stand users to check monitor height and viewing distance when they switch.
• You use a desk converter. Colorado State notes that desk-on-desk converters may restrict monitor height and viewing distance. Our desk converter setup guide covers screen placement on converters.
• Your desk is shallow. Duke’s standards call for a work surface at least 24 inches deep for adequate viewing distance, and the University of Washington suggests at least 30 inches when the keyboard sits at the front and the monitors at the back. An arm lets you push the screen back past the desk’s rear edge or pull it forward without a base in the way.
• More than one person uses the desk, or you often rotate the screen to portrait or swing it aside for paperwork.
• You use two monitors. Duke recommends placing dual monitors side by side, as close as possible, with the center between them lined up with the keyboard. A dual arm makes it easier to match the height of both screens.

When a Monitor Stand Is the Right Call

• Your monitor has no VESA mounting holes. Check the back of the monitor or its manual. Without them, an arm has nothing standard to attach to.
• Your desk cannot take a mount. Glass tops, thin or hollow desktops, desks with a deep rear lip or no gap behind them may not fit a clamp, and drilling a grommet hole is not an option on every desk. Check the arm’s listed desk thickness range against your desk.
• You set the screen once and leave it. If you only sit, and the monitor’s own stand or a riser gets the top of the screen to eye level, an arm adds little.
• You want storage under the screen. The University of Washington points out that the space under a riser can hold documents, keeping the area in front of you clear.
• You move the setup often, for example between rooms or desks, since a stand needs no mounting.

What to Check Before Buying Either One

• Monitor weight, both ends of the range. Arm makers list a minimum and a maximum weight per arm. For example, VIVO lists its STAND-V002O dual arm at 4.4 to 19.8 lb per arm. VIVO describes its arms as counterbalancing the monitor’s weight, so a screen outside the listed range may not hold its position. Use the monitor’s weight without its stand, from the manufacturer’s spec sheet.
• VESA pattern. The arm’s listed patterns (that VIVO arm lists 75 x 75 mm and 100 x 100 mm) must match the holes on your monitor.
• Desk thickness for the clamp and the grommet. These can differ. The same VIVO page lists a clamp range of 0.4 to 3.1 inches and a grommet range of 0.4 to 1.9 inches, while another section of that page says the clamp fits desktops up to 3.3 inches thick. When a listing disagrees with itself, go by the more conservative figure or check the installation manual.
• Screen size range listed by the arm’s maker, especially for ultrawide monitors; some makers sell separate arms rated for them.
• Height reach. Measure from the desktop to where the top of your screen should be, seated and standing if you use a sit-stand desk, and compare it with the stand’s or arm’s height range.
• Stability. On a standing desk, a heavy arm and monitor clamped at the back edge adds load at the top of the frame. Check the desk’s weight capacity and the arm maker’s instructions.

Frequently Asked Questions

Is a monitor arm better than a stand for ergonomics?

Not automatically. Ergonomics guidance cares about where the screen ends up: about an arm’s length away, with the top of the screen at or slightly below eye level. An arm makes it easier to get there and to readjust, which is why programs such as Duke’s list arms as an option. A height-adjustable stand or a riser can reach the same position if you rarely change it.

Can I use a monitor arm on a standing desk?

Yes, and it is a common pairing, since the arm rides up and down with the desk. Check that the clamp fits the desktop thickness, that nothing under the desk blocks the clamp, and that the combined weight stays within the desk’s listed capacity. Our standing desk guide lists desktop and capacity specs for each model.

What if my monitor has no VESA holes?

Use the included stand, a riser or a height-adjustable stand, and check the monitor maker’s guidance before trying any mounting workaround.

Should I put my monitor on books or on the computer tower?

Stacking can work as a temporary fix if the result is stable, but Duke’s standards say monitors should sit on the work surface or an arm, not on the computer or a docking station, and OSHA notes the computer case usually raises the screen too high. A purpose-made riser is steadier and easier to adjust.

How high should my monitor be when I sit in a properly adjusted chair?

Set the chair first, then the screen. Once your office chair is adjusted, place the top line of the screen at or slightly below eye level, and lower it further if you wear bifocals.

Conclusion

Pick a monitor arm if you change positions, share the desk, have a shallow desktop or use two screens, and confirm the VESA pattern, weight range and desk thickness first. Pick a stand or riser if your monitor lacks VESA holes, your desk cannot take a mount, or you set the screen once. Either way, finish by checking the result against the targets above: roughly an arm’s length away and the top of the screen at or below eye level.
