How much vertical range does a monitor arm actually give you?

Most commercial gas spring arms offer 13–16 inches of vertical travel from lowest to highest. Fixed-spring models typically give 8–12 inches. If you're pairing the arm with a sit-stand desk, choose one with 15 inches or more of vertical range — standing positions require the monitor to be 8–12 inches higher than the seated position to maintain the same eye-level relationship. FindOfficeFurniture.com lists vertical height range on every arm — call 888-719-4960 for sit-stand compatible recommendations.
