Go and measure your desk. Not the width — everyone gets the width roughly right. Measure front edge to back edge, in millimetres, and write it down. If that number starts with a 6, you already know why your second screen is at a weird angle and why every A1 print ends up on the floor.
Depth is the number that matters, and it's the one almost nobody selling desks talks about. Buy depth first, load capacity second, and worry about whether it goes up and down last. An 1800 × 900mm fixed desk on a solid frame will serve an architect better than a wobbly 1400 × 700mm electric sit-stand at the same price, every single time. That's the verdict. Here's the reasoning, because the reasoning is where you'll find the three or four details that actually change what you buy.
Your Desk Brief Is Not an Office Worker's Desk Brief
The standard home-office desk is sized for a laptop, a mug, and a notebook. That's it. That's the entire design brief, and 700mm of depth covers it comfortably.
Now write the brief you actually have. Two screens, at least one of them 27 inches, ideally on arms. A keyboard and mouse in front of them, at a distance where your elbows sit at your sides rather than out in front of you. A drawing tablet, if you sketch digitally. And — the bit no office worker ever needs — the ability to clear a space and spread a printed drawing flat while the screens stay live, because you are checking the print against the model.
An A1 sheet is 594 × 841mm under ISO 216. Laid landscape, that's 594mm of depth gone before you've put anything else on the desk. A monitor arm clamps to the back edge and eats another 80–100mm of that back strip. Do that sum and 700mm is already over-subscribed; the print overhangs the front edge and you're reading it at a tilt with your forearms holding it down.
800mm is the working minimum. 900mm is where it stops being a compromise — at 900 you can spread an A1 landscape, keep a keyboard in front of it, and still have the screens pushed far enough back that you're not craning. Go past 900 and you start struggling to reach the back of the desk, which is its own annoyance.
Width is easier. 1600mm is the sensible floor for dual screens plus any physical work at all. 1800mm is the number I'd give anyone with the wall for it, because 1800 gives you two zones — a digital zone and a hands zone — instead of one zone you keep having to clear.
Run the Load Sum Before You Buy the Arm
This is the check that separates people who've set up a workstation from people who've read about setting one up.
A monitor arm doesn't load the desk vertically. It loads it as a cantilever. A 7kg screen held 500mm out from the clamp is a lever trying to peel that clamp off the back edge and fold the desktop upward at the same time. Two of them, both extended, on a 15mm chipboard top, and you get exactly what you'd expect: a visible bow in the desktop and a clamp that needs retightening every month.
So before you buy anything, add it up honestly. Two 27-inch screens without their factory stands, two arms, a laptop, a docking station, a stack of reference books, a cutting mat, and whatever tower or external drives live up there. In my experience that adds up faster than people expect, and it's before you've dumped a box of samples on it for an afternoon.
Then check three things against that number:
The frame's stated load rating. Flexispot publishes a load rating for its sit-stand frames; so does every reputable maker. Read it, and read whether it's the static rating or the lifting rating — a motor can hold more than it can raise. If the manufacturer won't tell you, that tells you something.
The desktop's own stiffness. A frame rated for a lot of weight doesn't stop a thin, unsupported top from sagging in the middle. Depth makes this worse, not better, because a deeper top is a longer span between the front edge and the frame.
The arm's own spec. Ergotron publishes a weight range for the LX desk mount, and the number that matters is your monitor's weight without its stand — which is in the monitor's own spec sheet, not on the box. A screen outside the arm's range will either droop or refuse to stay up, and no amount of tension adjustment fixes it.
The Clamp Check Nobody Tells You to Do
Four things stop a monitor arm from mounting to a desk you've already bought, and you can check all four with a tape measure.
Edge thickness — most clamps have a maximum, and a chunky solid-timber top can exceed it. Bullnose or heavily rounded front and rear edges, which look lovely and give the clamp nothing flat to grip. A cross-brace or cable tray running directly under the back edge, exactly where the clamp jaw wants to go — this is extremely common on sit-stand frames, and it can push your arm 200mm off-centre. And grommet holes: if the desk has one, a grommet mount is stronger than a clamp, but only if the hole is where you want the screen.
On a sit-stand desk specifically, check the underside at the back, not the middle. That's where the controller box, the cable tray and the crossbar all live.
Where Sit-Stand Gets Oversold
I'm not going to tell you what standing does to your spine, because I haven't read the studies and neither has the person who wrote the article you read before this one. What I can tell you is what happens to the mechanism when an architect uses it.
The pitch for sit-stand is cycling: forty minutes down, twenty up, repeat. That pattern suits work that comes in discrete chunks — email, calls, admin. It does not suit what we actually do. A modelling session in Revit or Rhino is a single continuous act of concentration that runs for hours, and the moment you interrupt it to press a button, you've broken the thing you were holding in your head. In practice the desk gets raised once in the first week, admired, and then lives at sitting height for the next three years, having cost several hundred pounds more than a fixed frame and introduced a wobble you didn't have before.
There are two cases where I'd say buy the motors without hesitation. First, if the desk is shared — a partner, a housemate, anyone else with a different leg length — because the alternative is one of you being wrong all day. Second, if you do a lot of hand drawing or model work, because a raised, wide desk at standing height is genuinely better for both, and that's a real change of posture rather than a timer going off.
Everything else the reviews warn you about is true and boring. It needs a socket. The cable management is a permanent low-grade irritation. Assembly takes an afternoon.
The Wobble Test That Actually Discriminates
Every showroom demo has you push the desk sideways at full height and go "hmm, a bit of sway." That's the wrong test. Lateral sway is annoying; it isn't what ruins your work.
Push down. Hard, with the heel of your hand, near the front edge, at standing height — the way you'd lean on a drawing to hold it flat, or bear down with a scalpel on a cutting mat, or press a stylus into a tablet. A two-stage frame with loose column tolerances will give under that, and the give is what makes your line wrong. Then do it again one-handed at a front corner, which is where the torsion shows up.
As a rule of thumb, three-stage frames are stiffer than two-stage at full extension, crossbars help a lot, and a heavier top damps the whole thing. If you're buying online and can't do the test, buy a heavy top.
Two Surfaces Beat One Moving Surface
Here's the alternative nobody in the search results offers, and it's the one I'd give most people setting up a spare room.
Buy a fixed desk at the correct sitting height for you, deep and wide and stiff. Then add a second, higher surface elsewhere in the room — a drafting board, a bench, a kitchen-height run of worktop against the opposite wall. One for screens, one for standing, cutting, laying out prints and photographing models.
It's usually cheaper than a decent electric frame. It's immovably rigid at both heights. Nothing has a motor in it. And it changes your posture and your position and your view, which is far more of a break than standing in exactly the same spot looking at exactly the same screen. The physical-to-digital shuffle that architecture actually involves works better across two surfaces than on one that goes up and down.
If you only have wall for one desk, fine — buy the fixed one deep, and get a separate cutting surface you can put on top of it.
Where the Desk Goes Matters as Much as Which Desk
Don't put the desk facing the window, and don't put it with the window directly behind you. Facing the window, you're squinting past a bright field all afternoon. Backing onto it, every screen is a mirror.
Perpendicular to the window is the answer, and it's not just about glare. If you do any colour-critical rendering or you photograph models on the desk, side light that changes slowly through the day is far easier to judge and correct for than light coming straight at you or straight over your shoulder. Blackout blinds help with the render work; for model photography, the north-facing side of a room is the one you want. (For the screen half of that problem, our monitor guide goes into calibration properly.)
Surface Material: The Groove Problem
Laminate over MDF or chipboard is fine, durable, wipe-clean, and cheap. Its failure mode is the edge — chip the laminate lip with a dropped scale rule and it lifts.
Veneer looks better and behaves worse. A scalpel slip through a cutting mat scores it, and that scored groove is permanent. It matters more than it sounds: every drawing you tape down afterwards sits over that groove, and everything you rule across it goes slightly wrong.
Solid timber and good birch ply are the forgiving ones. They take marks, they sand back, and they're stiff enough to stop the cantilever sag from a monitor arm. Whatever you buy, a big self-healing cutting mat living permanently on the model-making half of the desk is the cheapest insurance there is.
Three Desks, Three Budgets
Cheap and genuinely good: a ply top on drawer units. A sheet of 18mm birch ply is 2440 × 1220mm, so one sheet cut down gives you an 1800 × 900mm top with material left over for a shelf. Oil it, round the front edge slightly but leave the back edge square and flat so an arm can clamp to it, and sit it on two IKEA Alex drawer units. It's rigid, it's exactly the dimensions you specified rather than the ones a manufacturer chose, and the drawers hold everything an architect owns. Fixed height, so measure your seated elbow height before you cut the legs or choose the units.
The sensible middle: a Flexispot E7 frame with your own top. Buy the frame alone rather than a frame-and-top bundle, and put the ply top on it. You get the sit-stand mechanism, a published load rating to check your sum against, three-stage legs, and — crucially — a desktop at 900mm deep instead of the 700 or 750 most bundles ship with. IKEA's Idåsen is the tidier, more expensive version of the same idea if you'd rather it arrived in one box.
If you're spending properly: Humanscale Float. It's counterbalanced rather than motorised — you unlatch it and lift it with one hand, which sidesteps the whole business of controller boxes, power cords and firmware. It's rigid, it's built to be repaired rather than replaced, and it's the one premium sit-stand I've used where the height change is frictionless enough that you actually do it. Steelcase and Herman Miller's electric offerings are also excellent and will cost about the same; the choice between them is fit and finish, not function.
What I wouldn't buy at any price: a 1400 × 700mm sit-stand with a bundled particleboard top, however good the reviews are. It's the right mechanism attached to the wrong brief.
Spend the Money on Depth, Then Forget About It
A desk is the least interesting piece of kit in a studio and the one that shapes your day most. Get it deep, get it stiff, get the clamp check right, and you can stop thinking about it for a decade.
Then the only variable left is what you do on it. That's the harder problem, and it's the one we spend our time on — ArchAdemia is where architects and students come to get better at the work itself: the drawings, the software, the portfolio, the business of running projects. Cancel anytime.
Measure the depth. Everything else follows from that number.
