The Desk Setup

The order to set a desk up in

A desk setup is a chain, not a checklist. Every adjustment you make removes freedom from the next one, so if you set them in the wrong order you will end up going back and undoing your own work. The order that holds is: the floor, then the chair, then your hands, then the screen, then the light.

Most people go the other way round — they start with the screen, because that’s the thing they’re looking at, and finish with the chair, because it’s the thing they think of as “ergonomic.” That’s how you end up adjusting the same four things forever.

Why order matters at all

There is one genuinely fixed object in most setups: the desk. It was built to a single height and it isn’t going anywhere. Everything else in the room is either adjustable or movable, and it all has to arrange itself around that one fixed number.

That gives you a dependency chain. Your chair height determines whether your hands sit at desk level. Your hands’ position determines how close you can pull the chair in. How close you sit determines how far the screen can be. How far the screen is determines whether you lean toward it, which determines whether you’re still using the backrest you carefully set.

Change something early in that chain and everything after it is now wrong. Change something late in the chain and you’ve only fixed that one thing. So you work forwards: fix the earliest constraint first, then don’t touch it again.

The sequence

DESK SETUP — the order
  1. Floor      Is the chair on something that lets it stay put?
  2. Chair      Height set so your hands land at desk level, not
                so your feet land on the floor.
  3. Feet       Whatever the chair height left you with — a box.
  4. Back       Seat depth, then lumbar height, then recline.
  5. Hands      Keyboard and mouse close enough to reach without
                leaving the backrest.
  6. Screen     Height, then distance, then tilt.
  7. Light      Where it comes from, and whether it's on the screen.

Seven steps, and steps 2 and 5 are the ones that carry everything else.

Step 1, the floor. Almost nobody checks this and it changes step 2. A chair that rolls away when you shift, or sinks over the course of an hour, means every other setting is provisional. Sort out what the chair is standing on before you start measuring anything against it.

Step 2, the chair. The counterintuitive one. You set chair height for your hands, not your feet, because the desk height is fixed and your hands have to meet it. Chair height starts at the floor covers this in full, including what to do when the chair can’t get there.

Step 3, the feet. Whatever gap step 2 left under your feet is now a separate problem with a separate object. A box. A ream of paper. Books. This is not a compromise, it’s the correct fix.

Step 4, the back. Seat depth first, because it decides whether you can reach the backrest at all; then where the lumbar curve lands; then how far back you want to sit. Deferred to here because all three are easier to judge once the height is settled.

Step 5, the hands. Keyboard and mouse pulled in close. Reach, not wrist angle, is the thing to fix — if you have to lean or extend to reach the mouse, you’ve lost the backrest and steps 3 and 4 stop mattering.

Step 6, the screen. Now, and only now, because how far away it can go depends on how close you’re sitting and how deep the desk is. Monitor height and distance is the detail.

Step 7, the light. Last, because it’s the only step that doesn’t constrain any of the others — and first to be blamed for headaches that are actually glare.

Where people start instead

Three common entry points, and what each one costs.

Starting with the monitor. You set the screen where it looks comfortable from where you happen to be sitting. Then you fix the chair, your eye height changes, and the screen is wrong again. Harmless, just wasted effort — unless you mounted the riser permanently, in which case you’ve now baked in a height derived from a chair setting you were about to change.

Starting with the feet. The commonest one, and the most expensive, because it’s the version everyone was taught. Feet flat, thighs level, done — and now the desk is above your elbows and your shoulders come up to meet it. You’ll feel this as tight shoulders and a stiff neck by mid-afternoon, and you’ll almost certainly diagnose it as a monitor problem or a posture problem, because the shoulders are nowhere near the feet.

Starting with a purchase. A new chair, or a standing desk, or a keyboard. The trouble isn’t that these are bad objects; it’s that dropping a new object into an unordered setup gives you a different set of wrong settings rather than fewer. A sit-stand desk in particular hands you a second full setup to get wrong.

Redo it when something changes

The chain is only valid for the inputs you set it with. So it needs redoing when:

  • You change chair, or desk, or shoes. Shoes genuinely count — a couple of centimetres of sole changes step 3, which is why a footrest set in winter boots is wrong in summer.
  • You change screens, or add one.
  • The room changes — the desk moves, the seasons change where the sun comes through the window.
  • You start sharing the desk. Two bodies cannot share one chair setting. If someone else uses your desk, expect to reset steps 2 to 5 every time, and accept that you’ll do it badly. Note which chair positions are yours by feel, not by the little numbered markings, which lie.

What the order doesn’t fix

An ordered setup removes reasons to hold tension. That’s the entire claim, and it’s a real one, but it stops there.

No arrangement of furniture is good for four hours. A well-set desk that you don’t leave will still leave you stiff, because the problem at that point isn’t the geometry, it’s the duration. Getting up and moving is the other half of this, and it’s a different subject from the one this site covers.

And if you have pain that persists, or pain that travels down an arm or a leg, or numbness, tingling or weakness anywhere, that’s a reason to see a clinician rather than a reason to spend another evening adjusting a chair. Furniture is not a treatment.

Start at step 1. The first three steps are usually where the whole thing was wrong.
