What size exercise ball should I sit on?
Choose a ball that fits your height.
Get a 26 inch ball (65 cm) if you are between 5 feet (1.5 m) 8 inches (173 cm) and 6 feet (1.8 m) 1 inch (185 cm). If you are 6 feet (1.8 m) 2 inches or taller, you will need a ball that measures 30 inches (75 cm).

Are exercise balls good for losing weight?
