What is the ergonomically correct monitor height for a monitor arm?

Per OSHA and ergonomic guidelines, the top edge of the monitor screen should be at or just below eye level — approximately 20"–24" from the user's eyes at the primary viewing angle. For most seated adults, this places the monitor center at approximately 4"–6" above the desk surface. Monitor arms allow fine-tuning this positioning, unlike fixed stands. Users who wear bifocal glasses may need the monitor slightly lower. At OfficeFurniture2go.com, we recommend an arm with ±15" height range for full adjustability — call 1-800-460-0858.
