Exercise balls are sized by their diameter in centimeters. Your height determines what size ball you need. For general exercise applications, a 45 cm ball is appropriate for anyone up to 5 feet tall. A 55 cm ball suits those 5 feet to 5 feet, 5 inches; a 65 cm ball suits individuals who are 5 feet, 5 inches up to 6 feet; a 75 cm ball is appropriate for those over 6 feet. Hard-to-find 85 cm exercise balls are appropriate for individuals over 6 feet, 8 inches.
If you’re using the exercise ball as a chair, however, the University of Minnesota Extension recommends using a ball one size larger than you would for typical exercise. So, for example, an individual up to 5 feet tall would bump up to a 55 cm exercise ball.
