When buying a ball, it's important not to overlook the correct size. There are two common ways to estimate the correct diameter of a ball:
How to Choose a Gymnastics Ball
Exercise balls have a variety of uses; primarily, they can serve as a rehabilitation aid or as a replacement for a traditional office chair. They help prevent health issues such as muscle and back pain and constantly encourage us to maintain a natural and healthy posture. In short, exercise balls are suitable for everyone, from children and adults to seniors.
Selecting a Size
1. The length of the arm from the shoulder to the fingertips
- 56–65 cm – 55 cm ball
- 66–80 cm – 65 cm ball
- 81–90 cm – 75-cm ball
- 91 cm and up – 85 cm ball
Also take your body weight into account. If you weigh more than 100 kilograms, a balloon with a larger diameter will be more suitable for you.

Selecting a Size
Keep in mind that you won't get very far by inflating a ball with your mouth. Save your lungs and use a standard pump or a portable compressor instead. Only inflate a ball that has been warmed to room temperature to avoid damaging the outer or inner layers.
