Before buying a monitor arm, should you prioritize weight or screen size?

When choosing a monitor arm, should you prioritize the allowed load capacity and monitor weight, or the monitor size?

While monitor weight and arm load capacity are crucial for stability and load-bearing, monitor size affects the arm's balance and flexible adjustability.

1. Monitor Weight and Arm Load Capacity

Manufacturers provide this specification to indicate the maximum weight the arm can support. This parameter is influenced by several mechanical factors, including material composition, joints, movement mechanisms, force calculations, inertial loads, safety tests, working environment, and more.

If the monitor is too heavy for the arm's limit, the arm cannot provide stable, safe support, potentially leading to damage, drops, breakage, and harm to equipment and users.

Therefore, you should choose arm models with a maximum load capacity 1-2 kg greater than your monitor's weight to increase the arm's durability and lifespan. If the arm's load capacity is 10 kg, the monitor can weigh 8-9 kg. This helps prevent the arm from constantly sagging or users having to overtighten screws, which indirectly reduces the arm's flexibility when moving it.

2. Monitor Size and Arm Support Capability

When manufacturers specify the maximum monitor size an arm can support, this affects the space users need for the monitor to move freely and at multiple angles as desired. Larger monitors require a sufficiently long arm to allow for movement and adjustment.

For example, if you have a large 32-inch monitor but only use an arm designed for 27-inch monitors (even if the 32-inch monitor weighs less than or equal to the arm's load capacity), you will still struggle to rotate the monitor vertically because the arm is not designed with sufficient height. In this case, the arm's flexibility is lost, isn't it?

Furthermore, the arm must be designed to be stable and well-balanced when adjusting the monitor, as larger monitors are more prone to losing balance or tilting if the arm does not support that size.

3. When buying a monitor arm, should you prioritize arm load capacity or monitor size?

Although weight is an important factor, monitor size cannot be overlooked. A large monitor might be lighter than a small one but still requires a longer arm to provide more flexible adjustment. Conversely, a small but heavy monitor will require an arm with a high load capacity.

Therefore, you should consider both factors when choosing a monitor arm. However, many users tend to focus only on the monitor's size in inches rather than its weight in kilograms. Thus, you can ask for assistance from staff to confirm if the arm you want to buy will be compatible with your current monitor at home.
