Adding one of the best monitor arms to your workspace can the final touch to make sure that you're comfortable and ergonomically sound for long sessions at your desk. It doesn't matter if you want the best monitor arm for a home office or for a commercial offer – they're a great idea either way. The might seem a bit much for the home, but there are really well priced options, and there's a good chance that future-you (and future-your-back) will thank you for it.

The best monitors arms give you fine 3D positioning of your screen, even if you monitor itself doesn't have good physical adjustments. It's said that you should be able to just touch the screen with your fingertips, and your eyeline should be level with the top of the display. Using tilt or swivel features can help to keep your screen clear of reflections, so you're not straining your eyes.

As an added bonus, the best monitors arms help to keep your desk and workspace clearer, because there's no monitor stand (although see our best monitor stands if you want one of those). That means more space for notebooks, graphics tablets or anything else you'd like freedom to store and position. Generally, our picks for monitor arms attach to the rear edge of your desk, and some attach to the wall, so you get a lot of desk space back. Most arms include cable management too, making everything pleasingly neat and tidy.

It's standard for monitors to be mountable with VESA standard mounts (though do double-check yours before buying), and all of the monitor arms on this list are VESA compatible. And most arms can comfortable support the average screen, but if you've got one that's especially large or heavy, check the weight the arm you're looking at supports. iMacs can even be mounted on arms, though you’ll need to ask Apple for a VESA plate to add to it when you buy it, and you'll want to buy a sturdy arm.

The best monitor arms 2021: the list

Best monitor arm: AmazonBasics Single Monitor Display Mounting Arm

01. AmazonBasics Premium Single Monitor Stand

Best monitor arm overall

Weight: 3.54kg / 7.8lbs | Dimensions: 65 x 15.2 x 41.1cm / 25.6 x 6 x 16.2in | Max monitor size: 32in | Max monitor weight: 25lbs / 11.3kg

Cable management system limited

We rate AmazonBasics' Premium Single Monitor Stand so highly because it'll do the job so well for the vast majority of people. It works well, and it's inexpensive – exactly what you want! It's easy to set up in the first place, and then and then only a light touch is needed to shift your screen around as needed. The arm can move a monitor outward up to 25in (64cm), and it offers a 13in (33cm) height range. 

This can be attached to the edge of a desk or table between 0.4in and 2.5in thick, or it can be attached to the wall – all the fittings for either option are included. When you don't need the screen and would like some extra space, you can easily push the arm back – it folds back over itself, so it tucks above the edge of the desk. It's compatible with screens up to 32, and can take all but the heaviest options. You can tilt between 70 degrees back and 5 degrees forward. The only weaker point is its cable management system, but it actually still works just fine, really.

There have been stock issues in the last year or so, but it seems to have settled down now – still, if you're keen on an arm and you see it in stock, maybe don't hang around too long.

02. Ergotron LX Desk Mount LCD Arm

The second best monitor arm overall

Weight: 3.6kg / 8lbs | Dimensions: 45.72 x 26.92 x 17.6cm / 18 x 10.6 x 6.93in | Max monitor size: 32in | Max monitor weight: 25lbs / 11.3kg

Good cable management

If you want a neater and easier cable-tidying system than the Amazon model above and are happy to pay a little extra for it, this is the arm for you. The Ergotron LX Desk Mount LCD Arm works like a dream: setting it up is no hassle at all, and it moves or can be folded away at the back of the desk with minimal effort. 

Just like the Amazon arm, it has 25 inches for forward and backwards extension, and the height can be moved within a 13-inch range (although if you're really tall, it has a variant model that's an even better choice – it's number 7 on this list). The industrial design is fairly nice, so with the good cable routing too, this is a good one for those who want clean aesthetics. The only potential downside is that this for desk mounting (either with the clamp or a grommet) only – you can't wall mount.

03. NB North Bayou Monitor Desk Mount Stand

The best monitor arm on a budget

Weight: 2.1kg / 4.6lbs | Dimensions: 38.5 x 28.5 x 9.5cm / 15.1 x 11.2 x 3.7in | Max monitor size: 30in | Max monitor weight: 19.8lbs / 8.9kg

Low price
Can't rotate 90 degrees

If you want one of the best monitor arms for the most affordable price, then grab NB's North Bayou Monitor Desk Mount Stand. It offers a good discount over the other models here, but will absolutely hold your screen where you need it. It won't take screens quite as big and heavy as some of the arms here, but that may not be a problem for you depending on your setup. And, admittedly, it looks like something that should be putting together car panels. 

It uses a gаs spring system to hold your monitor stable, but this keeps it easy to adjust. It enables you to tilt your monitor between +35 and -50 degrees, rotate it from -30 to +85 degrees so you can switch between landscape and portrait rapidly, and share your screen with others through the swivel function. It fixes to your desk via a clamp or grommet, though again there's no wall-mount option. It's just excellent value overall.

Best monitor arm: 3M Dual-Swivel Monitor Arm

04. 3M Dual-Swivel Monitor Arm

The best monitor arm for heavy monitors

Weight: 3.38kg / 7.45lbs | Dimensions: 46.7 x 22.9 x 13.8cm / 18 x 10.6 x 6.93in | Max monitor size: 27in | Max monitor weight: 13.6kg / 30lbs

Superior weight capacity
Great cable management
Challenging to assemble

If you've got a serious display with some serious weight to it, then the best monitor arm for you is the 3M Dual-Swivel Monitor Arm. It promises to bear the weight of a screen up to 30lbs/13.6kg, which is a huge amount in this context – keep in mind that a 27-inch iMac (which includes a whole computer, too!) only weighs 20lbs.

This rock-solid and reliable arm offers desk mounting, either via a clamp on desks up up to 4.25in thick, or a grommet in desks up to 2.25in thick. The height adjustment range of 18.5 inches (thanks to poly adjustments as well as arm adjustments) is especially impressive, and it extends up to 19.5in / 49.5cm from the base. You can also easily rotate your monitor from landscape to portrait. The hollow insides mean you can run your wires right through it, so it's good looking as well as tough (just like you). However, it's one of the more fiddly monitors here to get set up, and some find it a bit stiffer to move than the lighter-weight competition.

05. Vari Dual-Monitor Arm

The best monitor arm for dual monitors

Weight: 7kg / 15.4lbs | Dimensions: 4.25 x 14in / 10.8 x 35.5cm | Max monitor size: 24in per arm | Max monitor weight: 19.8lbs / 8.9kg per arm

Supports two monitors
Challenging to assemble

Need the best monitor arm to hold dual monitors side by side? The Vari Dual-Monitor Arm is our recommendation for getting the ergonomic benefits of an arm with the working space benefits of a dual-screen setup. Each of its two arms can hold a monitor up to 24 inches, and that weighs up to 19.8 lbs/8.9kg. That obviously limits the type of monitors you can attach much more than any of the single-arm monitors we've featured here, so bear that in mind.

However, if it still seems like a good fit for you, you'll love the height adjustment range of 12 inches, and the maximum arm extension of 29 inches. Both monitors can actually rotate through a full 360 degrees, as long as you don't knock them together while trying it. It's held in place by a clamp that will work with desks up to two inches thick, which again is a little more limiting than some options here. It's also more tricky to put together than many of the options here, but maybe that's no surprise when it's twofer. It comes with all the tools you need, at least, and there's a built-in cable management clip.

Best monitor arm: Ergotron LX Dual Stacking Arm

06. Ergotron LX Dual Stacking Arm

The most flexible dual-monitor arm

Weight: 7.18kg | Dimensions: 48.7 x 38.7 x 22.9cm | Max monitor size: 24 inches | Max monitor weight : 20 lbs (9.1 kg) per arm

Stack multiple monitors
Tall option available 
Sturdy design
Not cheap

Mounting monitors side-by-side not futuristic enough for you? The Ergotron LX Dual Stacking Arm enables you to put your screens one above the other, or side by side. No surprise that this comes with size restrictions again: you'll need to stick with monitors of 24 inches and under, and a weight of 20lbs/9kg and under. Beyond that, though, the flexibility here guarantees it's place in the best monitor arm list.

Well, not literally – it'll hold your monitors totally stable, while still offering height adjustment of up to 13 inches. There's a special tall model available if you're a tall model yourself, with extra range to that adjustment so make sure you get the right height. The foldable arms tuck away nicely when you're not using them despite the double-decker design. If you want to go all-out, then purchasing two arms and other accessories allows you to configure up to four monitors at once. 

Best monitor arm: Ergotron LX Desk Mount LCD Monitor Arm, Tall Pole

07. Ergotron LX Desk Mount LCD Monitor Arm, Tall Pole

The best monitor arm for tall people

Weight: 4.99kg / 11lbs | Dimensions: 58.4 x 18.4 x 28.6cm / 23 x 7.2 x 11.2in | Max monitor size: 34in | Max monitor weight: 25lbs / 11.3kg


If you're over six feet tall, then many of the best monitor arms may not offer the full range of height adjustment you need to nail the egonomics of your workspace. This Ergotron model is one of several that combines an arm with an adjustable pole for extra height control, and we think it's the best option for most people. 

The Tall Pole version of the LX Desk Mount LCD Arm (which you'll have seen at number 2 on our list) adds an extra 6.25in / 15.8cm of pole height in addition to range the arm has, so even Shaq should be able to get his monitor in just the right spot. Beyond that, its specs are the same as its smaller sibling, and it's just as good, though adding the pole costs you a little more (sorry, tall people).
