Seat Height for Your Height: The Lookup Table

Every chair listing tells you its seat height range. None of them tell you what yours should be, so the number is useless on its own.

Picked on published fit specifications, not on hands-on testing. How we pick.

The short answer

Your seat height should match the distance from the floor to the crease behind your knee, in shoes. If you cannot measure that, the tables below estimate it from your standing height: roughly a quarter of it, with the arithmetic shown so you can check us.

This page sits under Chairs That Fit Your Body. If you want the fit numbers before the shortlist, start with the seat height guide and the seat depth guide.

The measurement that decides it is called popliteal height

Popliteal height is the vertical distance from the floor to the crease behind your knee when you are sitting with your feet flat and your knees at about ninety degrees. It is the only body dimension that determines correct seat height, and almost nobody knows theirs.

The rule is straightforward: a chair's minimum seat height must be at or below your popliteal height, measured in the shoes you actually wear at your desk. If the chair bottoms out above that number, your feet cannot sit flat, and you will spend every working day compensating for it.

Measure it yourself in two minutes

Put on the shoes you wear at your desk. Sole thickness is part of the number.
Sit on a hard, flat surface - a kitchen chair or a table edge - with your feet flat and your lower legs vertical.
Measure from the floor to the underside of your thigh at the crease behind your knee.
That number is your target minimum seat height. Write it down.

If the surface you are sitting on is too high for your feet to reach flat, stack books under your feet until your lower legs are vertical, then measure from the top of the stack and add the stack height back on.

If you cannot measure: estimate from your standing height

The published anthropometric tables let you estimate it, and we are going to show the arithmetic rather than hand you a number to trust.

The BIFMA-derived reference tables give, for the 5th to 95th percentile of US adults, a standing height of 60.2 to 68.4 inches for women and 64.8 to 73.5 inches for men, against a popliteal height of 15.0 to 18.1 inches for women and 16.7 to 19.9 inches for men. Dividing one by the other at each end:

15.0 / 60.2 = 0.249
18.1 / 68.4 = 0.265
16.7 / 64.8 = 0.258
19.9 / 73.5 = 0.271

So popliteal height lands between about 25% and 27% of standing height across that whole dataset. The table below uses 0.25 for the seat height a chair must be able to reach - the conservative end, because if your real measurement is higher you can always raise the chair, whereas a chair that will not go low enough can never be fixed - and 0.27 for the height you will want available at the top of the range.

Estimated seat height by standing height (derived from BIFMA 5th-95th percentile data; arithmetic shown above)
Your standing height	In inches	Chair must go DOWN to at least	Chair should go UP to about
4 ft 10 in	58"	14.5"	15.7"
5 ft 0 in	60"	15.0"	16.2"
5 ft 2 in	62"	15.5"	16.7"
5 ft 4 in	64"	16.0"	17.3"
5 ft 6 in	66"	16.5"	17.8"
5 ft 8 in	68"	17.0"	18.4"
5 ft 10 in	70"	17.5"	18.9"
6 ft 0 in	72"	18.0"	19.4"
6 ft 2 in	74"	18.5"	20.0"
6 ft 4 in	76"	19.0"	20.5"
6 ft 6 in	78"	19.5"	21.1"

Which chairs actually go low enough

These are the published minimums for the chairs in our registry, sourced on each product page. Note how few clear 16 inches, and note the gaps - several brands publish overall chair height and no seat height at all, which is a real limitation when this is the number that decides the purchase.

Published minimum seat heights (see each review for the source)
Chair	Published minimum	Fits down to roughly
Herman Miller Aeron, size A	14.4 in	4 ft 10 in
Herman Miller Aeron, size B	14.8 in	4 ft 11 in
Herman Miller Aeron, size C	15.8 in	5 ft 3 in
Steelcase Leap v2	16.0 in	5 ft 4 in
Herman Miller Embody	16.0 in	5 ft 4 in
Steelcase Series 1	16.5 in	5 ft 6 in
Branch Ergonomic Chair	17.0 in	5 ft 8 in
HON Ignition 2.0 Big and Tall	17.0 in	5 ft 8 in
Autonomous ErgoChair Pro	18.5 in	6 ft 2 in
Sihoo M57 / Doro C300	Not published	Unknown - measure before buying
Hbada E3 Pro	Not published	Unknown - Hbada claims a 5 ft 1 in fit floor

The right-hand column is the standing height whose 0.25 estimate equals that minimum. It is an estimate of the shortest person the chair can properly seat, not a rule. Measure yours if you can.

What to do when the chair still will not go low enough

If you are stuck with a chair whose minimum is above your number - a fixed chair at an office, or a chair you already bought - a footrest solves it completely. Raise your effective floor to meet your feet. This is not a compromise; it produces the same joint angles as a correctly low chair.

What does not work is leaving your feet dangling and hoping, or perching forward to get your toes down. Both transfer load into your lower back and the underside of your thighs. See can office chairs cause back pain for what that does over time.

When you should deliberately sit higher than this table says

Two cases, both legitimate:

Hip discomfort. Sitting one to two inches above your popliteal height opens the hip angle, which many people with desk hip pain find easier. Add a footrest to keep your feet supported. See best chairs for hip pain.
A desk you cannot lower. If the desk is fixed and too high, raising the chair and adding a footrest is far better than leaving the chair low and shrugging your shoulders to reach the keyboard all day.

Both are deliberate deviations from the standard target, made for a stated reason. That is different from sitting too high because the chair will not go lower.

The other number you need

Seat height is half of the fit problem. The other half is seat depth - whether the pan is longer than your thigh - and it is the one that produces the "pressure behind my knees" complaint. Work through the seat depth guide next; between the two numbers you can eliminate most of the market in five minutes.

Questions people actually ask

What seat height do I need if I am 5 foot 2?

Around 15.5 inches, using the 0.25 estimate in the table above. Very few mainstream chairs go that low. The Herman Miller Aeron in an A or B size does; most chairs with a 17-inch minimum do not, and you would need a footrest with them.

What if my chair only goes down to 17 inches?

Use a footrest. Raising your effective floor produces the same joint angles as a lower chair and costs a fraction of a replacement. It is a genuine fix, not a workaround.

Should I measure with shoes on or off?

With the shoes you actually wear at your desk. Sole thickness is typically half an inch to an inch and it is part of the number, not noise.

Is a quarter of my height accurate enough?

It is an estimate derived from population data, and individuals vary - leg-to-torso proportion differs between people of the same height. It is good enough to filter a shortlist. Measure yourself before you spend serious money.

Why do chair makers not publish this?

Some do, in a fashion. Autonomous publishes a fit range of 5 ft 4 in to 6 ft 6 in, and Hbada claims 5 ft 1 in to 6 ft 5 in. Most publish a seat height range and leave you to work out whether it matches you, and several publish only overall chair height, which tells you nothing useful about where the seat sits.
