How does a monitor arm affect desk weight distribution?

A monitor arm redistributes the monitor's weight from the center of the desk (where a monitor stand sits) to the desk edge (where the clamp attaches). For desks with a particleboard or MDF core, this concentrated edge loading is generally within the desk's structural capacity for monitors under 20 lbs. For heavier monitors (20–30+ lbs), use a wide clamp jaw that distributes force over a longer edge span, or use a grommet mount that directs force vertically through the desktop rather than at the edge. Glass desks require wide mounting plates and must be rated for the arm's clamping pressure.
