What is the Best Exercise Ball Size for my Height?

Best Exercise Ball Size - Choosing the Right Size Ball 2021

What is the best exercise ball size for me? That is an excellent question because an exercise ball that is too small or too large for your body type can be uncomfortable and make it hard to do the exercises you want to do.

It stands to reason that a larger diameter ball should be able to provide a more challenging workout. It should also be able to withstand more weight than a smaller ball. (If you’re plus size, go for an exercise ball designed for heavy guys)

But is this always the case?

It depends.

Fitness ball manufacturers take many different approaches to determine the diameter of their balls. Some go with the standard 55 cm (22 inches) diameter, while others go as small as 30 cm (12 inches) or as large as 75 cm (30 inches).

Fortunately, there are a few tricks you can use to determine what exercise ball size is ideal for you. (You may even want to use a tape measure and measure your body to be sure you are not buying a ball that will be too large for the space you have.)

Before you buy, you should ask yourself what kind of workout you want to get out of the ball.

Choosing the Best Exercise Ball Size Guidelines

The following table should be able to help you get the best exercise ball for your height..

Your HeightBall Size (Diameter)
Under 4’8”45cm (18”)
4’8” to 5’3”55cm (22”)
5’4” to 5’10”65cm (26”)

NB: The rule of thumb when it comes to exercise ball sizing is that you want to be able to sit on the ball with your legs at a 90-degree angle.

Why an Exercise Ball?

An exercise ball is a great tool for improving posture, strengthening abdominal muscles, improving balance, and increasing flexibility.

By using an exercise ball to do sit-ups, you can not only tone your abs but also strengthen your muscles in your back and upper arms

Ball exercises are also effective for relieving back pain and combating stress and anxiety. Exercise balls are great for stretching and strengthening the back muscles in a neutral position. This is a great way to minimize lower back pain and improve posture.

An exercise ball can be used in place of a chair, to help you work your core without weights.
