What is the maximum monitor size a monitor arm can support?

Monitor arm maximum size ratings are specified in two ways: weight capacity (in pounds or kilograms) and screen size (in inches diagonal). Most single-monitor arms support screens up to 27"–32" and 15–20 lbs. Premium arms support up to 34"–38" screens at up to 25–30 lbs. Ultrawide monitors (49" super-ultrawide) require a specialized heavy-duty arm with a reinforced clamp and counterbalance — these typically rate to 33+ lbs. Never exceed the arm's stated weight rating; an overloaded arm will drift out of position or fail structurally. Always verify both the screen size rating and the weight rating before purchasing.
