Balls

1. What size Swiss Ball do I need?

Sizing a Swiss Ball for exercise:

The ball should be firm and the exerciser’s thighs should be parallel to the floor when sitting on the ball.

If your height is less than 5’2” you will need a 45cm ball
If your height is 5’2” to 5’8" you will need a 55cm ball
If your height is 5’9" to 6’3" you will need a 65cm ball
If your height is 6’4" to 6’9" you will need a 75cm ball

Sizing a Swiss Ball for using as a chair:

Use one size larger than you would need for exercise, and inflate until your thighs are parallel to the floor. The ball will be soft and more comfortable to sit on.

2. How much does the size really matter? If my husband is 5’10" and I am 5’5" can we get by using the same ball?

It is important to use the correct size ball for your height, properly inflated! In just the same way that it is uncomfortable to wear a pair of shoes that are too big or too small, exercising on a Swiss Ball that is the wrong size can cause problems. Using a ball that is incorrectly sized does not allow the body to move in correct postural alignment – which is an important part of training.
