Running a laptop next to an external monitor is one of the most common home office setups, and one of the most awkward. The laptop screen sits low on the desk, the monitor sits higher on its own stand, and your neck bounces between two different heights all day. A monitor arm with a laptop tray fixes that by putting both screens on the same adjustable system, at matched heights and distances. This guide covers the arm designs that work, how to size the tray, and the mistakes that make laptop-plus-monitor arms wobbly or hot.

Quick answer: For most people in 2026, the best monitor arm for laptop and external monitor is the 13–14 in — our #1 rated choice. See the full ranked comparison, alternatives and buying advice below.
Three ways to put a laptop and monitor on arms
Dual arm with a laptop tray on one side
The most popular setup: a dual monitor arm, with the monitor on one arm and a VESA laptop tray bolted to the other. Both screens adjust independently, so you can line up the top edges. Pick a dual arm where each side has its own spring and weight range, because a laptop plus tray (often 3 to 6 pounds) and a 27-inch monitor (often 9 to 15 pounds) need very different tension.
Pole-mount arm with a tray and a monitor bracket
Pole systems use a vertical column with brackets that slide up and down. They are cheaper and easy to reconfigure, but height changes require loosening a collar rather than just moving the screen. Good for setups you set once.
Single monitor arm plus a separate laptop stand
If you use the laptop’s keyboard, it may not belong on an arm at all. A single arm for the monitor and a folding laptop stand beside it is simpler, and the laptop stays within reach. This only works if you use an external keyboard and mouse, or accept typing on a raised laptop.
Sizing the laptop tray

| Laptop size | Typical width | Tray width to look for | Typical laptop weight |
|---|---|---|---|
| 13–14 in | 11.5–12.5 in | At least 12 in | 2.5–3.5 lb |
| 15–16 in | 13.5–14.5 in | 14–15 in or adjustable | 3.5–5.5 lb |
| 17 in / gaming | 15–16 in | 16 in or wider, heavy duty | 5–7+ lb |
Add the tray’s own weight (usually 1 to 2 pounds) to the laptop weight and check that total against the arm side’s minimum and maximum. This matters because a lightweight ultrabook on a tray can fall below the minimum rating of arms designed for heavier monitors, making the laptop side drift upward.
Tray features that matter
- Ventilation: a perforated or open-frame tray lets the laptop’s bottom vents breathe. A solid plate can make fans run constantly.
- Retention: a front lip or adjustable side clips stop the laptop sliding when you tilt the tray toward you.
- Tilt range: enough to angle the laptop screen to match the monitor.
- Cable pass-through: a gap for the charging and USB-C cables so they do not pull the laptop.
Laptop open or closed?
With the laptop open on a tray, the laptop screen becomes a second display. Position it at the same height as the monitor’s top edge and close to the monitor so the gap between screens is small. Some people prefer the laptop in “clamshell” mode, closed, with only the external monitor in use; in that case a vertical laptop holder on the desk is usually better than a tray, and the arm can be a single monitor arm.
Ergonomics of matching two different screens
- Top edges level: line up the top of the laptop screen and the monitor so your eye line stays constant.
- Primary screen in front: put whichever display you use most directly in front of your nose, and the other slightly angled to one side, rather than centering the seam between them.
- Distance: the laptop screen is smaller, so bring it a little closer than the monitor or increase its scaling in display settings to match text size.
- External keyboard and mouse: once the laptop is on an arm, typing on it is uncomfortable. Budget for an external keyboard.
Connecting it all with one cable
If your laptop supports it, one USB-C or Thunderbolt cable to a dock or a USB-C monitor can carry video, charging and peripherals, which keeps the tray tidy. Route that cable along the arm with clips, leaving a loop at each joint so the tray can swing without tugging the port.
Buying checklist
- Monitor weight and laptop-plus-tray weight both fit within their arm sides’ ranges.
- Arm supports independent tension per side.
- Tray is wide enough, ventilated and has a retention lip.
- Clamp or grommet fits the desk, and the desk can handle two loaded arms.
- Reach is long enough to bring both screens to about arm’s length.
FAQ
Can I put a laptop tray on any monitor arm?
Most VESA laptop trays fit any arm with a 75×75 or 100×100 VESA plate. The real question is weight: the laptop plus tray must fall within that arm’s rated range or it will drift.
Is it bad to keep a laptop on a tray all day?
Not if the tray is ventilated and the laptop is not pressed against a solid surface over its vents. Watch temperatures on thin gaming laptops and consider a closed-lid setup if they run hot.
Bottom line
The best monitor arm for a laptop and external monitor is usually a dual arm with independent tension on each side and a ventilated VESA laptop tray. Match both weights to the arm’s ratings, level the top edges of the screens, and add an external keyboard so the raised laptop becomes a true second display.
