The Height Fit Index
What desk height range do you need for your height? Your standing desk surface should sit at your standing elbow height, which averages 0.63 × your body height — about 40.3″ for a 5′4″ person, 43.5″ at 5′9″, and 46.6″ at 6′2″. For sitting, the desk must come down to your seated elbow height, roughly 0.385 × your height (about 26.6″ at 5′9″). A desk fits you only if its published minimum reaches your seated number and its maximum reaches your standing number. By that test, every desk we track fits standing users up to at least ≈6′4″ — the real differences are at the bottom: the Uplift V3 and FlexiSpot E7 Pro drop to the low 22s and fit seated users from roughly 4′11″, while the Branch Duo and FlexiSpot E5 stop in the mid-24s and start fitting seated work around 5′3″–5′4″ without a footrest. The full index, the arithmetic behind it, and the sources are below.

Reading the fit columns: "sitting fit from ≈5′4″" means users shorter than that will find the desk's minimum higher than their seated elbow height — workable, but only with a footrest or an under-desk keyboard tray. "Standing fit up to ≈6′5″" means taller users exceed the maximum and should add desktop thickness or a riser.
Methodology — stated in full
Standing. The standard ergonomic heuristic places the desk surface at standing elbow height, and published anthropometric proportions (Drillis & Contini, 1966, as reproduced in Winter's Biomechanics and Motor Control of Human Movement, Figure 4.1) put standing elbow height at 0.630 × body height (source PDF). The Canadian Centre for Occupational Health and Safety recommends light work at, to slightly below, elbow height (CCOHS, Working in a Standing Position). A desk therefore fits a standing user when its maximum height reaches 0.63 × their height: maximum ÷ 0.63 = tallest user fit. Example: 48.7″ ÷ 0.63 = 77.3″ ≈ 6′5″.
Sitting. The same Figure 4.1 proportions give greater-trochanter (hip) height as 0.530 × H and knee height as 0.285 × H. Approximating the seat at knee height, seated elbow height above the floor ≈ 0.285H + (0.630H − 0.530H) = 0.385 × body height. A desk fits a seated user when its minimum reaches down to that number: minimum ÷ 0.385 = shortest user fit. Example: 24.5″ ÷ 0.385 = 63.6″ ≈ 5′4″. This chains two population-average approximations, so treat it as a guide, not a verdict.
Caveats. These are population averages; individual leg-to-torso proportions vary, and the 90-degree elbow test on your own body beats any chart — including this one (our elbow-rule guide covers how). Manufacturer ranges for frame-only listings typically exclude desktop thickness; a 1″ top shifts both ends up an inch. Fit bands are rounded conservatively to the nearest inch.

Verdict: if you are under 5′4″ or sharing the desk, the low-minimum frames (Uplift V3, FlexiSpot E7 Pro) are the safe fit; everyone between 5′5″ and 6′4″ can pick on capacity and budget instead.

Complete your setup
Anti-Fatigue Mat
Standing on a hard floor for hours tires your feet fast — a cushioned mat makes standing sessions noticeably more comfortable.
Shop on Amazon →Monitor Arm
Frees up desk surface and lets you set your screen at true eye level, independent of your desk height.
Shop on Amazon →Cable Management Tray
An under-desk tray keeps power bricks and cords from swinging or tangling every time you raise the desk.
Shop on Amazon →Under-Desk Footrest
Supports a relaxed seated posture and gives your feet somewhere to shift during long sitting stretches.
Shop on Amazon →Under-Desk Drawer
Adds storage without drilling into the desktop — useful since most standing desk tops are bare slabs.

Your standing desk surface should sit at about 0.63 times your body height — roughly your standing elbow height. A 5'4" person needs about 40 inches standing; 5'9" about 43.5 inches; 6'2" about 46.6 inches. For sitting, the desk must drop to your seated elbow height, roughly 0.385 times your height — about 26.6 inches for a 5'9" person. Pick a desk whose published range covers both numbers.
It is a population-average heuristic from the Drillis and Contini (1966) anthropometric proportions, where standing elbow height is 0.630 of stature. Individual leg-to-torso ratios vary, so treat the computed number as a starting point and confirm with the 90-degree elbow test on your own body — arms relaxed, elbows bent to 90 degrees, the desk surface at forearm height.
Only above roughly 6'7". By the 0.63 rule, a 48.7-inch maximum covers standing users up to about 6'5", and a 50-inch maximum up to about 6'7". Users taller than that can add height with a thicker desktop or a riser. The more common failure is the other end: minimums around 24.5 inches sit too high for comfortable seated typing below about 5'4" without a footrest or keyboard tray.
A footrest raises your effective seated position, and an under-desk keyboard tray mounts the typing surface a few inches below the desktop. Both are cheaper than a different frame. This matters mostly for shorter users considering desks whose minimum is in the mid-24-inch range rather than the low-22s.
Ranges are quoted as the manufacturer publishes them, and frame-only listings typically measure to the top of the frame — a 1-inch desktop adds about an inch to both ends. If you are within an inch of either end of a desk's range, count your desktop thickness before deciding.
