The average bar-height bar stool is 30 inches tall, while the average counter-height bar stool is 26 inches tall. Short bar stools are 16 to 23 inches tall, and extra-tall bar stools are generally 33 to 36 inches tall.
Typically found in restaurants and bars, the design of bar-height stools allows them to fit comfortably under a standard 42-inch counter or bar top. Counter-height bar stools are common in home bars or kitchens. They provide comfortable seating on their own or under a 36-inch counter top. Short bar stools fit well under a standard table and are one alternative to dining room chairs.
