The stools of a counter height desk range in height from 23-27 inches (58.42 to 68.58 cm). Determining the correct height for your stool counter depends on two criteria: counter height and size of the primary user. Typically, a kitchen counter is 36 inches (91.44 cm) high, but it is not uncommon to see some as low as 30 inches (76.2 cm) or as high as 42 inches (106.68 cm). Ideally, a stool provides a counter between 10-13 inches (25.4 to 33.02 cm) of clearance between the top of the seat and the top of the counter. This measurement represents adequate legroom and a comfortable place to eat at the counter. Subtracting between 10-13 inch counter heights should provide a range of suitable height for the stool of your counter.
By knowing who is going to use the stool counter more often will help you decide how much space you need the stool under the counter height desk. If you have kids who eat breakfast and eat most of the snacks on the counter, some stools higher will help them better reach the counter. If you have friends that are higher than hang out in the kitchen every Sunday, with stools shorter for the counter can better accommodate their legs.
