How do I know what size ball I should buy?
This is the guide I used:
Exercise balls are available in a wide range of sizes, suitable for individuals under 4 feet, 6 inches to individuals who are more than 6 feet, 2 inches tall. Balls are sized in centimeters, and some companies may color code the balls to match the size. General size guidelines are accurate for most people; however, you may find a larger or smaller ball more comfortable if you are near the top or bottom size limit. Typically, individuals less than 4 feet, 6 inches require a 30 cm ball. You should choose a 45 cm ball if you are between 4 feet, 6 inches to 5 feet tall. From 5 feet to 5 feet, 5 inches, select a 55 cm ball. If you are between 5 feet, 6 inches and 6 feet, 2 inches, use a 65 cm ball. If your height exceeds 6 feet, 2 inches tall, opt for a 75 cm ball.
