A monitor arm lifts the screen off the desk, which gives you the depth back for a keyboard, notebook or laptop, and it lets you set the screen at the right height. The three single-monitor arms we compared are close in what they do; the differences are the weight range, the largest screen each lists, and how each one clamps to your desk. The WALI lists the widest range (up to 26.4 lb and 34-inch screens), while the HUANUO FlowLift and the VIVO both list 4.4 to 19.8 lb.
We have not tested these arms. Specifications come from the Amazon listings, checked on September 29, 2026. Where a listing does not say, we say so.
Three single-monitor arms compared
| HUANUO FlowLift | WALI Single Monitor Arm | VIVO Single Monitor Stand | |
|---|---|---|---|
| Screen size (as listed) | 13 to 32 inches | 13 to 34 inches (regular up to 32) | 17 to 32 inches |
| Stated weight range | 4.4 to 19.8 lb | Up to 26.4 lb flat, 19.8 lb curved | 4.4 to 19.8 lb |
| VESA patterns | 75 x 75 and 100 x 100 mm | Standard mounting holes (the bullet points we read do not name the patterns) | 75 x 75 and 100 x 100 mm |
| Movement (as listed) | Gas spring, stable at any angle | Extends 19.3 in, rises up to 17.3 in above the desk, swivel 180 degrees each way, tilt +70 and -45, rotate 360 | Mechanical spring, tilt 90 degrees either way, 180-degree swivel, 360-degree rotation |

Check your monitor against the three arms
Enter your screen’s diagonal size and weight from its specifications (the weight is usually listed without the stand), and the thickness of the desk edge where you will clamp it.
Will your monitor work with these arms?
Screen size and weight from your monitor spec, and the thickness of your desk edge.
Compares your numbers with the limits in the listings. The HUANUO listing we read does not give a clamp thickness. Check VESA compatibility as well.
The three arms
HUANUO FlowLift Single Monitor Mount (13 to 32 Inch)
A one-piece gas-spring arm that the listing says holds 4.4 to 19.8 lb on VESA 75 x 75 or 100 x 100 mm, stays put at any angle, and takes about 3 minutes to install. It lists both C-clamp and grommet mounting and a maker’s test of 20,000 movements.
- Good for: a typical 24 to 27 inch monitor and a quick, tool-light setup.
- Keep in mind: the weight range tops out at 19.8 lb, so heavy or ultra-wide screens are out, and the bullet points we read did not give a clamp thickness range.
WALI Adjustable Single Monitor Arm (13 to 34 Inch, up to 26.4 lb)
The widest range of the three: up to 34-inch screens and 26.4 lb for flat screens (19.8 lb for curved). The listing says the arm extends 19.3 inches, rises 17.3 inches above the desk and swivels, tilts and rotates. It lists a clamp or grommet mount for desks 0.39 to 2.76 inches thick.
- Good for: a larger or heavier screen, or a monitor you need to pull toward you.
- Keep in mind: it is the most complex of the three to position, and the reach of 19.3 inches means the arm needs clear space behind and to the side. The bullet points do not name the VESA patterns, so check them.
VIVO Single Monitor Stand, Mechanical Articulating Arm (17 to 32 Inch)
A mechanical-spring arm for 17 to 32 inch screens between 4.4 and 19.8 lb with VESA 75 x 75 or 100 x 100 mm. The listing lists a 180-degree swivel, 360-degree rotation and a tilt of 90 degrees either way, with a C-clamp for desk tops up to 3.1 inches thick and an optional grommet mount.
- Good for: a simple arm for a mid-size monitor on a thick desk.
- Keep in mind: the listing warns that the back of the arm extends past the edge of the desk, so it needs space against a wall.
How to choose a monitor arm for a small desk
- Weight and size first. Use the tool above. A monitor outside the arm’s stated weight or size range will droop or not fit.
- VESA. Check that your monitor has the mounting holes the arm uses (75 x 75 or 100 x 100 mm). If it does not, you cannot use the arm.
- Your desk. The desk edge must be thick enough and strong enough to clamp. Thin, glass, hollow or lipped edges may not work. If the desk has a rear crossbar or a shelf, the clamp may not fit.
- Screen height. OSHA says the top of the screen should be at or slightly below eye level (OSHA monitor guidance). The arm has to be able to reach that height, so measure yours.
- Viewing distance. The preferred distance is 20 to 40 inches from your eyes. An arm lets you move the screen back on a shallow desk.
- Wall clearance. Some arms extend beyond the back edge of the desk when folded. Leave space or choose a shorter arm.
If you are also planning cables, see our cable management guide. To raise a monitor without an arm, see the notes in how to maximize space on a small desk.
Frequently asked questions
Do monitor arms work on small desks?
Yes, if the desk edge can take a clamp. An arm frees the surface under the screen for other items.
How do I know if my monitor fits an arm?
Check the screen size, the weight and the VESA mounting holes on the back. All three must match the arm’s limits.
How high should a monitor be?
OSHA says the top of the screen should be at or slightly below eye level, and the preferred viewing distance is 20 to 40 inches.
Can I use a monitor arm on a glass or thin desk?
Not usually. Check the maker’s clamp thickness range and the strength of the desk edge.
Are gas-spring arms better than mechanical-spring arms?
They work differently. Gas springs adjust smoothly to the weight, while mechanical springs balance the load by design. Check the weight range for each.
