Counter Height vs Bar Height

How to use this tool

1. Measure from the floor to the top of your counter, bar or table.
2. Type the height in the height input. You can enter inches or centimeters. The tool converts between them, using 1 in = 2.54 cm exactly.
3. To see an example first, try a preset: “Table 30 in”, “Counter 36 in”, “Bar 42 in” or “Counter 91 cm”.
4. Read the stool seat height range. The tool calculates it from your height and the gap between seat and surface.
5. Check which row of the surface chart your height falls in. Where the bar and tall bar ranges overlap at 43 to 45 in, both rows are shown.
6. Compare the result with the seat heights the guides list for that class, such as counter stools at 24 to 27 in or bar stools at 28 to 33 in.
7. To change the gap, open “More options”. The smallest and largest gap start at 10 and 12 in. Change them if your seating needs a different gap.
8. If you see an error, check the input. Errors appear for a missing or non-numeric height, a height of zero or less, a smallest gap larger than the largest gap, or a gap as large as the surface height. A warning appears for a height outside 24 to 60 in.

Presets are a quick way to test the tool. Change the number in the height input at any time to see a new result.

How is the stool seat height worked out from counter height?

The tool subtracts a gap from the surface height: seat height = surface height − gap. Four guides (B, D, E and L) say the seat sits 10 to 12 in below the surface. One guide (C) says a stool sits 10 in lower than the counter. That is why the default gap is 10 to 12 in.

For a 36 in counter, 36 − 12 = 24 in and 36 − 10 = 26 in. The rule gives a seat of 24 to 26 in, which is 61 to 66 cm. The guides list counter stool seats at 24 to 27 in, so the two ranges are close but not identical. A 42 in bar gives 30 to 32 in by the rule. A 30 in dining table gives 18 to 20 in. The guides list dining chair seats at 17 to 20 in.

The gap is the only input that changes the rule. A wider gap lowers the seat, and a narrower gap raises it. Use “More options” to test a different gap, and compare the result with the guide figures before you decide.

Why do the counter and bar ranges overlap, and why do the guides disagree?

The surface ranges overlap because the guides do not put each class in a separate band. Bar is 40 to 45 in and tall bar or bistro is 43 to 48 in, so both rows include 43 to 45 in. A surface at 44 in appears in both rows. A height between the listed ranges, such as 39 in, is reported as falling between them, and no listed seat heights are shown.

Each row shows the lowest-to-highest range across the guides. Next to it, each guide’s own figure appears with its letter (A to F, or L). Nothing is averaged. Guide A is the NKBA kitchen planning guidelines, which plan seating at 30, 36 and 42 in high. Counter height is 36 in by guides A and F, 34 to 36 in by one guide, 35 to 37 in by one guide, and 34 to 38 in by one guide. Bar height is 42 in by guides A and F, 40 to 42 in by two guides, 41 to 43 in by one guide, and 40 to 45 in by one guide.

The rule and the guides do not fully agree for bars. At 42 in, the rule gives 30 to 32 in. The guides list bar stool seats at 28 to 30 in (guides B, D and L) and up to 33 in (guide C). The tool shows both results so you can see the difference. The figures come from published sizing guides, not a standard, so no single result is correct for every room.

Frequently asked questions

What is the difference between counter height and bar height?

The guides list counter height at 34 to 38 in and bar height at 40 to 45 in, both measured from the floor to the top of the surface. The tool shows both ranges and the guide figures behind them. Enter your own height to see which row it falls in.

What seat height does a 36 inch counter give?

The rule gives a stool seat of 24 to 26 in, which is 61 to 66 cm. The guides list counter stool seats at 24 to 27 in. Both figures are calculated from typical sizes, so check the result against your own seating.

Why does a bar height result show two different seat ranges?

The rule and the guides do not fully agree for bars. At 42 in, the rule gives 30 to 32 in, while the guides list 28 to 30 in and up to 33 in. The tool shows both so you can compare them. Neither one is a correct answer for every room.

What happens if I enter 39 inches?

The tool reports that 39 in falls between the listed ranges, since counter tops end at 38 in and bars start at 40 in. No listed seat heights are shown for that height.

Why do I see a warning when I enter a height?

A warning appears for a height outside 24 to 60 in. Check that you measured from the floor to the top of the surface and entered the number in inches or centimeters.
