Standing desk specs, explained

The two numbers that matter most, and the two most inconsistently published. Across this catalog the floor runs from 22″ on the Ergonofis Sway to 30.6″ on the Ergotron WorkFit-D, and the ceiling from 44.6″ to 52.6″ on the FlexiSpot E7 Plus.

The trap is what the number includes. Some makers publish the frame alone, some publish the frame with their standard top on it, and the difference is the thickness of that top — usually 0.75″ to 1.2″, occasionally 1.75″ on a solid slab. A frame quoted at 22.8″ becomes about 24.3″ with a butcher block, which moves the shortest person it fits by nearly four inches. Every desk page here carries a height basis line saying which of the two the figures are, because comparing a frame-only number against a with-top number is the single easiest mistake to make when cross-shopping.

Total travel is the useful summary: the widest here is 27″ on the EFFYDESK Nimble Standing Desk, the narrowest 17.3″ on the Branch Four Leg Standing Desk.

This is the one number on this site that is ours rather than a manufacturer's, and it is an estimate. Every desk-height calculator rests on two anthropometric heuristics: standing elbow height is roughly 0.62 of stature, and seated elbow height roughly 0.4. A desk works for a person when it can drop to their seated elbow height and rise to their standing one.

Inverting those two ratios gives the range of people a desk fits:

So a desk reaching 22″ to 48.3″ — the Ergonofis Sway — is estimated to fit 4′7″ to 6′6″. A desk that stops at 29″ at the bottom cannot reach a seated elbow height for anyone under about 6′1″, which is why a 29″ minimum is a real limitation rather than a rounding detail.

What it does not account for. Torso-to-leg proportion varies between people of the same height, so measure your own elbow heights if you can — they are the real specification and these ratios only stand in for them. A keyboard tray lowers the effective typing surface by two to three inches and is the standard rescue for a desk that will not go low enough. A thick top and casters raise both ends. And for a desktop converter only the standing half applies, because its sitting height belongs to the desk underneath it.

Across the catalog, 21 of 41 full desks get low enough for someone 5′2″, and 39 of 44 reach high enough for someone 6′4″.

A desk leg is a set of telescoping tubes. Two stages means two segments, three means three — and a third segment collapses shorter and extends taller from the same footprint. That is the whole difference, and it buys range rather than strength. 25 of the 44 desks here are three-stage.

Here the three-stage frames travel 24.8 to 27 inches, and the two-stage ones anywhere from 17.3 to 26.3: three stages make a wide range near-certain, where a two-stage desk has to be checked. Three stages also usually move faster, because every segment travels at once. What they do not do is make a desk stiffer or stronger — some of the highest-rated frames in this catalog are two-stage, including the Deskhaus Apex Pro at 600 lb.

Choose stages for range and leg count for stability. They are separate decisions and conflating them is how people end up paying for a three-stage desk that still wobbles. Longer version.

Single-motor desks drive both legs from one motor through a linkage shaft; dual motors give each leg its own. Dual is faster, quieter and more reliable under load, and at this point nearly everything worth buying has it. Four-motor desks put one in each of four legs. 5 desks here have four; 4 have none at all.

Travel speed runs from 1 in/s to 2 in/s on the UPLIFT V3 L-Shaped Standing Desk. It sounds trivial and is not: at 1.0 inches per second a 20-inch change takes about 20 seconds, at 2.0 it takes 10, and the difference is felt every time you change position.

Published noise runs from 40 dB on the Desky Dual Sit Stand Desk to 50 dB. Fifty decibels is audible in a quiet room and on a call. Many manufacturers publish nothing at all, which is worth reading as missing data rather than as a good figure.

Rated lift runs from 25 lb on the Ergotron WorkFit-Z Mini to 661 lb on the Desky Quad Sit Stand Desk. Most people never approach either. A 27-inch monitor is about 15 pounds, a dual monitor arm about 10, a laptop and a dock under 10, and a solid 60×30 butcher block around 70.

Where it does matter: a heavy slab plus a tower bolted under the desk plus a loaded multi-monitor arm can reach 150 pounds without anything unusual, and a frame near its rating is slower, noisier and works harder every cycle. Note also that some makers publish a static load higher than the lift rating — a desk that can hold 540 lb standing still may only lift 440.

What capacity does not describe is stillness. It is a statement about motors, not about how much the surface moves when you type on it at full height.

Front-to-back sway at standing height is the most common complaint about standing desks, and it is geometry rather than build quality. A raised desk is a tall structure loaded at the top: the higher it goes the longer the lever, so the same nudge moves the surface further. A wide top makes it worse because the ends overhang the legs.

Three things in the spec sheet predict it. Leg count first — four legs roughly halve the unsupported span and are the only structural fix; 5 desks here have them. A crossbar second, which triangulates two legs at the cost of the floor space underneath — 3 of 44 desks here have one, and 41 deliberately do not. Leg profile third: square and rectangular columns resist twisting better than round ones in the same steel.

Before replacing a wobbly desk, re-tighten every bolt between the frame and the top with the desk lowered, check that all the feet actually touch the floor, and move the legs outward if the frame allows. The full list of fixes.

Memory presets are the feature most likely to decide whether the desk gets used. A saved position is one button; without one you eyeball the height every time, and those desks reliably end up parked. Three or four is plenty. 33 desks here have three or more, and 6 have none — including some good ones where presets are a paid upgrade, which is worth catching at the point of order.

A digital height readout matters more than it sounds: it is how you set a preset to a measured number rather than a guess, how you stop the desk above a drawer unit, and how you reproduce a height that worked.

Anti-collision stops the desk when it meets an obstruction, and 39 of 44 desks here have some form of it. Two approaches: monitoring motor current for a spike, which is simple and common; and a gyro or accelerometer that senses the frame twisting, which reacts sooner. The behaviour on contact varies too — stopping is the minimum, reversing an inch or two is better, and it is the difference between a scratched drawer and a destroyed one.

The surface is where most of the visible money goes, and it is also the part you can change independently by buying a frame on its own. In rough order of cost: particle board with a melamine or laminate skin, engineered wood veneer, bamboo, rubberwood and other engineered hardwoods, then solid hardwood slabs.

Three practical notes. A one-piece top beats a two-piece one at the same price — a seam down the middle is the standard economy at the budget end and you feel it under a mouse. Thickness moves your height range, adding to both ends of a frame-only figure. And width drives stability more than material does: an 80-inch top on two legs will move at standing height whatever it is made of.

Depth is the specification people regret. Twenty-four inches is tight for a monitor at a comfortable viewing distance; thirty is the usual answer; a couple of desks here offer 23.6-inch depths specifically for narrow rooms.

A desk warranty is normally three numbers, and the frame figure is the flattering one. Frame cover here runs from 2 years to lifetime; the longest fixed term is 100 years on the iMovR Jaxson.

Read the electronics number instead. Steel frames rarely fail. Control boxes, keypads and motors do, typically five to eight years in, and plenty of desks advertising fifteen years on the frame cover the electronics for two. The gap between those two figures tells you what the company expects to break.

A long warranty is also only as good as the company still being there to honour it. A fifteen-year promise from a brand founded three years ago is a different proposition from a twelve-year one from a contract furniture maker with a dealer network, even though the bigger number belongs to the newer company. All three warranty figures in one table.

Assembly is the cost nobody budgets for. A 72-inch frame-and-top build is a genuine afternoon, and squaring the frame on the slab is the fiddly part. 14 of the desks here arrive with the top already fitted or as a bare frame instead.

Frame span is the compatibility number if you are bringing your own surface: the range of widths the base adjusts to. Your top should sit inside it with the legs somewhere near the middle third — too close to the ends leaves a long unsupported middle, too far in leaves long unsupported ends, and the second is worse.

Cable management is either included, optional or absent, and it is worth more than it sounds on a desk that moves: every cable has to tolerate 20-plus inches of travel several times a day, and a power strip mounted to the frame rather than the wall is what stops a plug being pulled out on the way up.

Approximate prices here run from ~$130 for the VIVO Manual Crank Desk Frame to ~$1,345 for the Herman Miller Jarvis Bamboo. They are hand-recorded snapshots from our last catalog update and will differ from any seller's price today, which is why every figure on this site is prefixed with a tilde.

Comparing them requires care, because they do not all buy the same object. Some are complete desks with a top, some are bare frames, and some are the entry configuration of a range that realistically costs half again as much once specified. Every desk page carries a line saying exactly what its price includes.

More money reliably buys range, warranty and surface quality. It does not reliably buy stability, which follows leg count rather than price. Where the money goes.
