The 7 Best Monitor Arms For A Thick Desk

If you buy something using the retail links in our articles, sometimes we earn a small affiliate commission. This does not impact the products we recommend.

Monitor arms are mounted to a desk by either a C-clamp (that slots over the desk edge), or a Grommet (that holds the arm in position using a hole in the desk surface).

The problem that comes with using a monitor arm on a thick desktop, or a desk that has full width drawers is that the C-clamp often isn’t wide enough to slot over the work surface.

In fact the widest C-clamp on an ‘off the shelf’ monitor arm can accommodate a 4″ desk thickness at the very most. 

This article will consider a range of single and dual monitor arms that are fitted with the widest C-clamps available, as well as looks into a couple of alternative ideas for how a monitor arm can be incorporated into your setup without compromising on the look of desktop.

Whilst the tables below focus on the best monitor arm for a thick desk, you might want to learn about how much weight a monitor arm can hold by checking out our full guide here.

The winner, and in our opinion best pick for a monitor arm for a thick desk goes to the Huanuo HNSS12. 

A solid performer across all categories, the HNSS12 has the capability of providing mobility to heavy screens up to 35″ in size, whilst securing everything in place with a clamp that slots over thick desktops up to 3.5″ in depth. 

The length of the arm when fully extended (almost 2 feet!) means this unit is better placed than any other to slot into a set-up on a multi-functional work space like a drawing table or craft station.

Simply attach the stand on the far corner of the desk and swing the monitor into action when needed.

Best Dual Monitor Arm For A Thick Desk

HUANUO HNDS6 Dual Monitor Arm
  • Increase Comfort & Productivity - This dual monitor stand raises monitors to eye level, improving posture, relieving strain on neck & shoulders while increasing productivity levels
  • Install In 10 Min or Less - The 1-piece gas spring arm simplifies the assembly. You just need to choose the proper mounting base and mount the monitors. The setup can be completed in 10 min or less
  • Optimize Your View and Workstation - The stand allows your monitor to swivel, tilt and rotate. Freely set your monitors to customized angle and position while saving up much valuable space on your desktop
  • Hold Your Monitor Stably - The solid construction and stable clamp/grommet base provide stable and secure holding for your monitors

Throughout all of our searching the Huanuo HNDS6 was the only monitor arm, single or dual, which offered the ability to attach to a desk with an edge thicker than 3.5″. 

As the primary design feature being assessed in this post, the ability to clamp onto at desk of up to 3.74″ in thickness meant  the HNDS6 won the ‘attach to the greatest width’ award by some margin.

Be mindful however that there are limitations on the weight bearing capabilities of this unit. Whilst 14.3lbs for each arm covers most monitors, it won’t cover them all. 

A further point to be aware of is that the fantastic articulated arms need about 6″ of room behind the desk to operate through all of their potential configurations.

They do however offer so many pivot points that you’ll likely have no issue customising a set-up that works for you whilst also allowing your desk to remain flush with a wall.

If you’re monitor is within the 95th percentile of weight and size (i.e. it’s no bigger than 32″ and weighs no more than 17.6lbs) then this arm should definitely make your shortlist.

Vivo have shown a little creativity by cleverly incorporating some neat blue LED lights into the casing of the GM1BB. A nice touch to if your gaming set-up features accents in blue or white. 

Of course, you don’t buy a monitor arm for its lights alone (they can be switched off by the way) and when measured and compared with others on this list the GM1BB is decent, if not a world beating unit. 

The ability to clamp onto a desk as wide as 3.5″ in thickness sure is useful but there are a little concerns raised amongst the reviews with build quality reportedly hit or miss with the weight of even light monitors causing the arm to sink.

It’s sometime too quick and easy to dismiss the idea of upgrading your monitor stand, especially if your monitor came with one as standard. 

Should the design of your workspace mean that a monitor arm just isn’t an option then an improved stand can still introduce a lot of the same benefits to your setup. 

Not only is the V001D just a beautiful design to look at, it brings with it functionality which introduces tilt and rotation. 

Handily too, the footprint of the stand is so minimal that the loss of desk real estate will barely be felt.

  • Wide Compatibility 17 to 32" Monitor Wall Mount - It’s built for monitor weights from 3.3-17.6lbs and should have backside mounting holes one of the four VESA sizes: 75x75mm / 100x100mm / 100x200mm / 200x200mm.
  • Premium Gas Spring Adjustment System - The built-in ultra-precision gas spring arm can smoothly adjust your monitor to any height and angle to meet your ergonomic requirements. The arm can extend up to 18.3 inches.
  • Full Motion Articulating Monitor Stand - This wall monitor arm supports up-down tilt ±90°, left-right swivel 180° and 360° rotation. Provide you with more comfortable viewing angle, help to reduce neck, shoulder and back pain, work more efficiently.
  • Save Space - Compared with the monitor clamped on the desk, the wall-mounted stand can save valuable space on the desktop. You don't need to worry about the bracket being close to the wall and cannot be extended. At the same time, it is more stable and will stay still while you are typing.

Sometimes making best use of a thick desk means not using it at all! 

If you need to maintain as much desk space as possible yet don’t have the luxury of having a work station that can host a monitor arm, then an alternative set-up using a wall mounted monitor stand could be your best option. 

If your desk is backed against a weight bearing wall the ERGEAR EGWSS1 will bring all the benefits of a monitor arm without the rather unsightly support pole. 

A huge range of motion provided by the long articulated gas spring arm means you’ll be able to bring the screen into a perfect viewing position from up to 18 inches away! 

This also creates the potential for it to be tucked well out of the way at the end of a shift (perfect for clean freaks!), or when you don’t want it in the way should you need the desk surface for another purpose.

Conveniently the size and weight limit of screens that can be held by the EGWSS1 is just as good as any of the desk based arms.

Round up

If you’ve been searching around for a monitor arm that can slot over a desk edge wider than 4″ the chances are you’ve come up empty handed. 

The design of many desks simply do not take into account the needs and wants to be retrofitted with a monitor arm. Occasionally you see some built in cable management features but those are the exception rather than the rule.

However the lack of suitable monitor arms shouldn’t get you down. Whilst they are the preferred choice to create a clean desk set-up they are by no means the only option.

Wall mounted monitor arms and after market stands provide the same tilt, swivel and rotate benefits whilst arguably looking even better. Don’t feel stuck when attempting to build yourself an ergonomic and productive work station.
