The number of stools you should purchase will be determined by the size of your kitchen area or living area and the number of feet surrounding your kitchen area or bar. You would be required to give the width about 2 feet and 3 feet mid-height of stalls, almost 3 feet. Consequently, whether it is 6 feet in length or not, you will be able to accommodate 3-4 bar stools based on the counter size.
