What is the maximum monitor size that a standard office monitor arm can hold?

Most standard single-monitor office arms are rated for monitors up to 27–32 inches and 8–20 lbs. Some heavier-duty single arms support up to 34–38 inch monitors at up to 27 lbs. Dual arms typically each support up to 24–27 inches per head. Beyond 34 inches, you need to look specifically for heavy-duty display arms rather than standard office monitor arms. The limiting factors are: VESA pattern size (larger monitors may use 200x200mm vs. standard 75/100mm), weight (heavier = more torque on the arm joints), and physical size (arm reach and width need to clear the monitor's width).
