It’s important to follow your own needs and determine the right size of yoga ball for you. You might find that you are more comfortable with a certain size, even though that size is smaller or bigger than what you would need based on your height. 

How to Choose the Yoga Ball Based on Different Situations? 

When you choose a yoga ball, you could be led by your height or by what you plan on using the ball for. 

Based on your height 

The easiest way to determine the right yoga ball size is to go by your height. 

First, start by measuring your exact height. You can do so by standing barefoot next to a wall and marking the spot at the top of your head. Then, measure that height with the help of a tape measure. 

Your height measurement will help you determine the size of the yoga ball that will be best for you. 

  • 18” (45 cm) ball – for people with 5 ft height or shorter (150 cm);
  • 22” (55 cm) ball – for people between 5 ft 1” to 5 ft 7” (155 cm to 170 cm);
  • 26” (65 cm) ball – for people 5 ft 8” to 6 ft 1”(173 cm to 185 cm);
  • 30” (75 cm) ball – for people above 6 ft 2” (188 cm).

It’s always a good idea to try the ball size before buying it. This will ensure that the ball is comfortable for you, no matter if it’s bigger or smaller than the one suggested by your height. 

If you have long legs or want to use the ball for excessive stretching, yoga poses, or back problems, go for a larger-sized ball. 

Based on the usage 

One significant usage of yoga balls is for chairs. Many people replaced their usual chairs with yoga ball chairs. If you plan on using your exercise ball as a chair, you need to buy a chair that is 4” (10 cm) higher than your current chair. When you sit on it, it will deflate by the pressure of your body, so make sure that your yoga ball chair is big enough for that. 

Furthermore, you should ensure that your exercise ball chair is firm and pumped at its maximum since that will make it sturdy and comfortable to sit on. 

Before buying your yoga ball, make sure that you try different sizes and see which one suits you best. One easy way to determine it is to sit on it and ensure that your knees and hips are bent at a right angle of 90 degrees. 

What to Do With Your Yoga Exercise Ball?

Yoga exercise balls have numerous usages. First and foremost, using an exercise ball during practice engages your muscles more since the surface is unstable. 

Next, a workout with an exercise ball will improve your flexibility, loosen up your hamstrings, and improve your lower back. It can also be suitable for stretching and performing a deep stretch.

Lastly, you can use your yoga exercise ball to improve spinal stability and flexibility.
