Choose a monitor arm if...
Your monitor has VESA 75 or 100 mounting holes, your desk edge can safely hold a clamp, and you want real adjustability — height, tilt, swivel — plus the desk surface fully cleared underneath the screen.

Monitor Arm vs Monitor Riser: Which One Should You Get?
If your monitor sits too low, the screen is too far back, or the stock stand is eating your desk, both a monitor arm and a monitor riser can fix it — but they fix it in very different ways. An arm floats the screen above a fully cleared desk. A riser is a simple platform that lifts the monitor a fixed few inches while giving you storage underneath.
The right choice comes down to three things: whether your monitor has VESA mounting holes, whether your desk edge can take a clamp, and how much height adjustment you actually need.

This guide is for remote workers deciding between the two most common ways to raise an external monitor on a small desk. It is research-based, not hands-on tested — model specs below are quoted from manufacturer and brand-listed sources, checked September 28, 2026.
What a monitor arm solves better
Full adjustability
A gas-spring arm lets you change height, tilt, and swivel with one hand. The HUANUO FlowLift, for example, lists a lift of up to 39.6 cm above the desk with tilt from −50° to +85° (per HUANUO's listing), so you can dial the screen to eye level and swing it around for video calls without rebuilding the setup.
The surface stays clear
An arm removes the stock stand entirely, so the whole area under the screen becomes usable desk space — keyboard, documents, a desk mat, whatever you actually reach for.
Cleaner cable routing
Most arms route power and display cables along the arm itself, which makes a small desk feel less visually crowded than a stand with cables trailing behind it.
What a monitor riser solves better
No mounting required
A riser is freestanding: you set it down and put the monitor on top. There are no VESA holes to check, no clamp to tighten, and no risk to a thin, glass, or otherwise clamp-unfriendly desk.
Storage underneath
The shelf a riser creates is usable space — 3M's MS80B is explicitly designed around columns that leave room underneath, and metal risers like BONTEC's include cable management and pen slots in the platform itself.
Simpler and cheaper
A riser is usually the least expensive way to raise a screen, assembles in minutes with basic hardware, and moves with zero effort when you rearrange the desk.
The spec reality check
Manufacturer specs make the tradeoff concrete. Arms give you range; risers give you a few fixed steps. Quoted from brand-listed sources, checked September 28, 2026:
Typical arm: wide range
HUANUO's FlowLift (HNSS6) lists 13–32 in monitors, 4.4–19.8 lbs, VESA 75/100, and up to 39.6 cm (about 15.6 in) of lift. ErGear's current single-arm listing states a similar envelope: 13–34 in, up to 19.8 lbs, VESA 75/100. Both offer C-clamp or grommet mounting.
Typical riser: fixed steps
3M's MS80B adjusts from 1 in to 5-7/8 in in 1-5/8 in increments and is rated to 80 lbs. BONTEC's metal riser offers three heights — 3.9 in, 4.7 in, 5.5 in — with a 44 lb (20 kg) capacity. Most risers land in the 3–6 in lift band.
What that means for ergonomics
The widely used ergonomic rule of thumb is the top of the screen at or just below eye level. If your monitor needs more than a few inches of lift to get there — common with taller people or low desks — a riser may top out before you do. Arms rarely have that problem.
Three checks that decide it
- Check the monitor's back panel. Look for the square four-hole VESA pattern (75×75 mm or 100×100 mm). If it is there, an arm is on the table. If it is not — common on very cheap or all-in-one style displays — a riser is the simpler route.
- Check the desk edge. Arms clamp to the back edge or bolt through a grommet hole, so the edge needs to be solid wood or similar, thick enough for the clamp (FlowLift lists 0.59–3.54 in), and free of crossbeams underneath. Glass tops, thin hollow-core slabs, and desks with a modesty panel usually rule the clamp out — see our clamp position guide and against-a-wall guide for the full checks.
- Check how much lift you need. Sit in your chair, close your eyes, open them, and note where your natural gaze lands. If the screen top is only a few inches below that line, a riser closes the gap. If it is much lower, only an arm gets you there without stacking books under a platform.
What to check before you buy either one
- Whether the monitor back has VESA 75 or 100 mounting holes.
- Whether the desk edge can hold a clamp safely — thickness, material, and clearance underneath.
- How many inches of lift the screen actually needs to reach a comfortable eye line.
- Whether the space under the screen matters to you — storage shelf versus fully clear surface.
- Whether you ever need to swing the screen toward you for calls or share it with someone beside you.
- Whether the desk may move or the setup will be rearranged often.
Final takeaway
If the monitor has VESA holes and the desk takes a clamp, a monitor arm is usually the better long-term upgrade: more adjustment, a fully clear surface, and cleaner cables. If either check fails — no VESA holes, a clamp-unfriendly desk, a rental you cannot modify — a monitor riser is the honest fix: a few inches of lift, storage underneath, and zero installation risk.
