Counter-height stools generally have a surface height of 35 to 39 inches and a stool height of 24 to 27 inches. By comparison, bar stools have a surface height of 41 to 43 inches and a stool height of 28 to 33 inches, with extra-tall bar stools measuring 44 to 47 inches for surface height and 33 to 36 inches for stool height.
Counter-height stools are typically sized for use with 36-inch counters. These stools are smaller than bar stools, and they are ideal for kitchens or home bars. They are slightly taller than table-height stools, which have surface heights of 28 to 30 inches and stool heights of 16 to 23 inches.
