Stand-up desks for tall people.
Look at max height first, since a 6'4" user works near 46 inches.

At 6'4", most people need a desk near 46 inches when standing, measured in work shoes, and at 6'6" near 47. At 6'0" that drops to about 43.5 inches, and at 5'9" to about 41. Arm and torso length shift these by about an inch. The desk height calculator gives your own range for sitting and standing.

Three-stage legs extend further than two-stage legs, which starts to matter once your standing height passes about 47 inches. The two-stage frames on this page top out between 45.3 and 48 inches with the top fitted. The Desk Pro 3-Stage reaches 52.7 inches, leaving headroom for users over 6'5" or anyone on a walking pad.

A desk is least stable at the top of its range, which is exactly where a tall user works every day. Dual or triple motors, wide feet, and a load well under the weight rating all reduce wobble. Test it at your own standing height, with monitors and arms mounted, within the return window.

Tall users need more than a high top end. Longer arms call for a desktop at least 29 inches deep, so the monitor sits at a comfortable distance rather than too close. When seated, check knee clearance under the frame and keyboard, since long thighs run out of room before the desk runs out of height.

A good desk for a tall person reaches past your standing elbow height with room to spare, stays steady at the top of its range, and has a deep top. At 6'4", that means a frame that reaches about 48 inches or more. Three-stage frames, which extend past 52 inches, cover users well above that.
