The best monitor arms might be exactly what you need to perfect the comfort and ergonomic setup of your workspace, whether that’s in a home office or a business premises. It’s really important to have your screen at the right height and distance if you want to keep your back in great condition, and a monitor arm gives you total control of that.

As a general rule, you should sit far enough away from the screen that your fingertips can just about touch it, and your eyes should be level with the top of the display. You might need to tilt or swivel your screen to make sure that you don’t get any distracting glare. A monitor arm helps you achieve all of this, even if your screen of choice doesn’t include these kinds of ergonomic adjustments.

A monitor arm can also be perfect for keeping your desk clearer, leaving more space for other working material – everything from notebooks to graphics tablets. Most of the arms we’re featuring attach to the back edge of your desk, meaning there’s almost no footprint on the desk itself. Some monitor arms attach to the wall, leaving you with even more space. The arms will generally include cable management too, so it all stays neat.

Most monitors will be mountable using the VESA standard, but do double check to make sure yours is. All the monitor arms on this list are VESA compatible, so you shouldn’t have any mounting issues if that’s the case. But you'll need to check that the arm you want can support the weight of your screen, if it's a beast. iMacs can even be arm mounted, but you’ll need to get a VESA plate from Apple when you purchase, and you’ll need a strong arm for it.

The best monitor arms available now

Best monitor arms: 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

The AmazonBasics' Premium Single Monitor Stand is worthy number one for our list by doing its job well, being simple to use, and being well-priced. What more do you want from a tool, right? Setting it up is really straightforward, and then it's easy to extend and retract the arm, tilt it for a better angle, or rotate your screen from landscape to portrait; just give it a light touch. The the arm more a monitor outward up to 25in (64cm), and it offers a 13in (33cm) height range. 

You can secure the monitor arm to a wall, or attach it to the edge of a desk or table that's between 0.4in and 2.5in thick, with all the fittings you need included. When you're not using the screen, you can easily push the arm to fold itself back over the edge of the desk, keeping the space clear. It holds monitors up to 32 inches in size, and all but the heaviest models will be within its weight limit. You can tilt between 70 degrees back and 5 degrees forward. The cable management system is its weakest point, but it's still fine, and doesn't change how good a choice this is overall.

The only problem? Amazon seems to have been struggling to keep it in stock – if you see it in stock now, don't miss out! Otherwise, we have very similar models right here that will do the job…

Best monitor arms: Ergotron LX Desk Mount LCD Monitor Arm

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

This is absolutely one of the best monitor arms, and if you want a slightly better cabling system than the Amazon model and don't mind paying a little more, you might even be better off picking it. The Ergotron LX Desk Mount LCD Arm is lightweight yet tough; it's no problem to get set up; it's easy to move, and it can be folded away with no effort. 

Like the Amazon model, you can use it to extend your monitor up to 25 inches, and the height of the monitor up to 13 inches (although if you're especially tall, we'd recommend its sister model; number 07 on our list). We really like the cable management, and the industrial design is pretty good for this kind of thing. This one is only for desk mounting (either with the clamp or a grommet), not wall mounting.

03. NB North Bayou Monitor Desk Mount Stand

The best budget monitor arm

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 need one of the best monitor arms on a low budget, then NB's North Bayou Monitor Desk Mount Stand is our recommendation. It costs a lot less than the other models here, but will still hold your screen in place safely – it's just that the screen can't be as big and heavy as some of the arms here can take. 

The gаs spring system keeps it stable but makes it easy to adjust, and you can tilt your monitor between +35 and -50 degrees, rotate it from -30 to +85 degrees, turn your display between landscape and portrait, and share your screen with others through the swivel function. It can be installed via desk clamp or grommet, and overall we're astounded by the excellent value this monitor arm represents.

Best monitor arms: 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 your display is especially heavy, then the 3M Dual-Swivel Monitor Arm is the best monitor arm to look at, thanks to its listed weight capacity of 30lbs / 13.6kg. That is a lot of monitor to support, bearing in mind that even the 27-inch iMac (which has a whole computer attached!) only weighs about 20lbs. 

This sturdy and reliable model can be set up in two different ways: either clamp it to a desk that's up to 4.25in thick or use the grommet mount to fits desks up to 2.25in thick. Once you're set up, the monitor arm provides an impressive 18.5 inches of height adjustability (thanks to poly adjustments as well as arm adjustments), extends 19.5in / 49.5cm from the base, and lets you rotate your monitor from landscape to portrait. Best of all, it's hollow so you can run your wires through it, making for a very tidy cable management solution. On the negative side, it's a little fiddly to assemble in practice, and some find it quite stuff.

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

Looking for the best monitor arm to support two screen side by side? This setup is ideal for giving you a lot of working space on a smaller desk, and the Vari Dual-Monitor Arm is our pick. Each of its twin arms can support a screen up to 24 inches, that weighs up to 19.8 lbs / 8.9kg. That will limit your monitor options, so keep that in mind before you decide to go down this route.

Assume it still fits the bill, you'll be pleased to know that it offers a height adjustment range of 12 inches, and a maximum arm extension of 29 inches. The monitors even rotate through a full 360 degrees (just try not to bash them together while doing it). The clamp will work with desks up to two inches thick. It's a bit more tricky to assemble than many of the options here, but at least the box includes tools to help you do so. There's a built-in cable management clip, too.

Best monitor arms: 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

Is mounting monitors side by side too basic for you? If you need the option of stacking them on top of each other as well as side by side, then the Ergotron LX Dual Stacking Arm is the best monitor arm option for you. Again, you're looking at more restrictions on size (24 inches max) and weight (up to 20lbs/9kg), but the flexibility here is top notch.

It gives you height adjustment of up to 13 inches, and there's a tall model available if you're a tall model yourself, 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 arms: 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 more than six feet tall, then even the best monitor arms won't necessarily hit the height you need for full ergonomic perfection. This Ergotron model is one of several that combines an arm with an adjustable pole for extra height control. The Tall Pole version of the LX Desk Mount LCD Arm (which features as number two on our list) adds an extra 6.25in / 15.8cm of pole height in addition to the arm, so even basketball players should be able to get their workspace set up for total comfort. Beyond that, it comes with all the specs and benefits of the shorter model, as listed previously, albeit at a slightly higher price.
