How to find the right Stability Ball

Stability balls come in various sizes. How do you choose the right size for your body?
Here’s some tips to help you find the right Stability Ball to get the most from your workouts and to prevent possible injuries.

You can actually test out different sizes of balls at the gym or a sporting goods store. If that is not an option, be sure to ask the return policy of the store, in case you need to exchange the stability ball for a different size.

Proper Stability ball Sizing

Sit Test: Sit on the stability ball with your back straight and feet flat on the floor. Your knees should be at a 90-degree angle. If so, then you are sitting on the correct stability ball for your height. If not, then you need to try another size.

Tape Measure Test: Many Stability balls include a pump and tape measure in the package.  Measure the full pumped, or inflated, stability ball to determine its height or circumference. If no tape measure is provided, then be sure to measure in centimeters, as this is the standard measurement used for stability balls .  Stability balls will have their size either on the box or printed on them, located near the hole used to inflate them.  Check the measured size with the suggested size to be sure you have properly inflated the ball.

Height:  Use the following height chart to determine the right size of stability ball for you:

Your Height Best Stability Ball Size
less than 5′ 0″
5′ 0″ to 5′ 5″
5′ 6″ to 6′ 1″
6′ 2″ to 6′ 8″
6′ 9″ and up
45 cm
55 cm
65 cm
75 cm
85 cm

When in doubt, go with a larger ball, rather than one that is small. You may prefer a larger ball if you have long legs, are very new to stability ball balance work, using it for yoga or stretching or as an office chair.

No matter what you do with the stability ball, it works the core, strengthens balance and supportive muscles, and is always fun to use!
