Bar Stool Height Guide: Counter vs Bar Height in Millimetres
The right bar stool height leaves about 250 mm between the top of the seat and the underside of the counter. In practice that means a seat of roughly 610–700 mm for a counter around 900 mm high, and 750–810 mm for a commercial bar of 1,000–1,100 mm. Measure the underside, not the top.
Key takeaways
- Measure from the floor to the underside of the counter or bar top, then subtract about 250 mm to find the seat height.
- Kitchen-style counters usually sit near 900 mm; EN 1116 provides for worktop heights of 850, 900 and 950 mm.
- Commercial bars typically sit at 1,000–1,100 mm and take bar-height stools of about 750–810 mm.
- Knee room under the overhang matters as much as seat height, especially for backed and swivel stools.
- Plan a lower counter section or nearby tables for guests who cannot use high seating.
Ordering stools at the wrong height is an easy mistake to make in a bar or café fit-out, and an expensive one to put right. Too tall and guests knock their knees on the underside; too short and they sit with their chin near the counter. Because counter and bar heights vary from venue to venue, there is no single “standard” stool to buy off a list. This guide sets out typical counter and bar heights in millimetres, the seat-to-counter gap most published guides agree on, how to measure an existing bar, and what to check on a sample before you commit to a full run of commercial bar stools.
Counter height vs bar height: what is the difference?
Counter height and bar height are two distinct surface heights, and each needs a different stool. Counter height follows kitchen worktop height. EN 1116, the European standard for coordinating sizes of kitchen furniture, provides for fixed worktop heights of 850, 900 and 950 mm (CATAS). Inside Out Contracts, a London-based contract furniture supplier, puts café and workspace counters at about 900 mm and gives an average commercial bar height of 1,000–1,100 mm (Inside Out Contracts).
Reference site Dimensions.com uses slightly different bands: counters at 890–1,020 mm, bars at 1,040–1,090 mm and a less common “tall bar” band at 1,120–1,190 mm (Dimensions.com). The tall band turns up on raised viewing rails and some cocktail bars, and it needs its own, taller stool. The overlap between the published ranges is the reason to work from your own measurements rather than a label on a product listing.
| Setting | Typical surface height | Typical stool seat height | Where the figures come from |
|---|---|---|---|
| Kitchen-style counter, café window bar | 850–950 mm (commonly about 900 mm) | 580–710 mm (650–700 mm often quoted) | EN 1116 via CATAS; Dimensions.com; Inside Out Contracts |
| Commercial bar | 1,000–1,100 mm | 740–810 mm (750–810 mm often quoted) | Inside Out Contracts; Dimensions.com |
| Tall bar or viewing rail | 1,120–1,190 mm | 840–910 mm | Dimensions.com |
| Low stool at a dining table | Standard dining table | 450–510 mm | Inside Out Contracts |
How to work out bar stool height: the 250 mm rule
Most guides converge on one figure: leave about 250 mm between the top of the seat and the underside of the surface. Dimensions.com gives 250 mm as a minimum, and Inside Out Contracts calls it the optimum. WebstaurantStore, a US catering supplier, frames the same idea as 9–12 inches of legroom, roughly 230–305 mm, so guests do not bump their knees (WebstaurantStore).
That gives a simple working formula: seat height = floor-to-underside height minus 250 mm, with about 25 mm either way for personal preference and seat padding. Two worked examples:
- Café counter: 900 mm to the top, 40 mm thick top, no apron. Underside 860 mm, so a seat of about 610 mm.
- Pub bar: 1,060 mm to the top, 50 mm thick top. Underside 1,010 mm, so a seat of about 760 mm.
Why the underside matters more than the top
Two counters with the same top height can need different stools. Thick solid timber or stone tops, aprons, under-counter shelving, drip rails and the brackets that hold an overhang all lower the point where a guest’s thigh meets the counter. Measure to the lowest obstruction at the position where people will actually sit, not to the worktop surface.
How to measure an existing bar or counter
Take measurements before you choose a stool design, and record them in the brief with a simple sketch.
- Floor to underside at several points along the run. Floors in older pubs are rarely level, so note the lowest reading as well as the typical one.
- Top thickness and any apron, rail or bracket that sits below the top.
- Overhang depth from the front edge to the bar face or cabinet front. This is the knee space.
- Floor finish. If new flooring, matting or a raised platform will go down after you measure, adjust the figures.
- Foot rail height, if the bar has a fixed rail. Guests may use it instead of the stool’s own footrest, so the two should sit at a similar level.
- Usable length of each run, for working out how many stools fit.
Knee room and overhang depth
Seat height only works if there is somewhere for the knees to go. The NKBA Kitchen Planning Guidelines, written for domestic kitchens but widely used as a reference, recommend 610 mm of width per seated diner, with 381 mm of knee-space depth at a 914 mm counter and 305 mm at a 1,067 mm counter (National Kitchen & Bath Association (NKBA)). Taller surfaces need less depth because guests sit more upright with their legs angled down.
A shallow overhang does not stop people using the counter, but it pushes them to sit sideways, which takes more length per guest and blocks the route behind. Backed and swivel stools are the least forgiving, because the back stops the seat sliding in close. If your overhang is short, a backless stool that tucks right under can be the better choice. Our guide to bar stool spacing covers the width side of the same problem.
Footrests, swivels and adjustable stools
A high stool without a footrest leaves feet hanging and gets uncomfortable within minutes. The footrest should sit where a seated guest’s knees bend comfortably, and it takes heavy, repeated scuffing, so specify a hard-wearing finish or a metal kick plate on timber frames. Check the position on the sample with staff of different heights rather than trusting a drawing.
Swivel seats make getting on and off easier along a tight counter but need more clear space either side and more knee room, because the seat rotates into the overhang. Gas-lift adjustable stools suit some counters, but a fixed-height frame has no lift mechanism to wear or be wound up and down by guests. If you do choose adjustable stools, ask how the mechanism is rated for commercial use. The swivel leather counter stool is an example of a design where seat height and swivel clearance both need to be set against the counter.
Accessibility: plan for guests who cannot use high seating
High stools exclude some guests, including many wheelchair users, older customers and children. For reception counters in buildings other than dwellings, Approved Document M Volume 2 recommends at least one section 1,500 mm wide with a surface no higher than 760 mm and a knee recess of at least 700 mm (GOV.UK). That paragraph is written for reception desks rather than bars, but it is a useful benchmark if you are designing a lowered section of bar or a serving counter. Agree the approach with your designer, access consultant or building control body.
Where a lowered section is not practical, keep standard-height tables near the bar so that a group can sit together. Poseur tables at bar height are another way to add high seating without a fixed counter; see our poseur table height guide for matching stools to them.
Common bar stool height mistakes
- Ordering by name (“counter” or “bar”) without measuring the underside.
- Forgetting that a new floor finish or platform changes every height.
- Using one stool design across a counter and a bar at different heights.
- Ignoring seat padding, which lowers the effective seat once someone sits down.
- Choosing a backed or swivel stool for a counter with very little overhang.
- Leaving the footrest position to chance.

Frequently asked questions
What height bar stool do I need for a 900 mm counter?
Measure the underside first. With a typical 30–40 mm top and no apron, the underside sits at about 860–870 mm, so a seat of roughly 610–620 mm leaves the recommended 250 mm gap. Published counter-stool ranges run from about 580 mm to 710 mm, so always check against your actual counter rather than a catalogue label.
What height stool suits a 1,050 mm pub bar?
If the bar top is around 50 mm thick, the underside is roughly 1,000 mm, which points to a seat of about 750 mm. That sits inside the 750–810 mm range usually quoted for commercial bar stools. A deeper top, apron or drip rail lowers the underside and means a lower seat.
Is counter height the same as bar height?
No. Counter height follows kitchen worktops at roughly 850–950 mm, while commercial bars typically sit at 1,000–1,100 mm. The difference is large enough that a stool made for one is uncomfortable at the other, so specify the stool to the surface it will serve.
Does an upholstered seat change the height I should order?
It can. Foam and seat pads compress when someone sits down, so the effective seat height is lower than the dimension on the drawing. Check the pre-production sample with a person seated on it, against your real counter, before you approve it.
Can bar stools be made to a specific seat height?
On a made-to-order project the seat height is part of the written specification, so you can state the figure that suits your counter. Give the floor-to-underside measurement in your brief and confirm it again on the sample before production starts.
