Sitting position is the best positition to check if the new ball is for appropriate height. At a 90-degree angle, your hips are level or slightly higher than the knees. When the exercise ball is too small, you might compromise the position of your hips and pelvis when sitting on it. On the other hand, a ball that is too large will not provide opportunities for your feet to touch the ground, putting you in an unstable position.

There is another approach to determining right exercise ball sizes is to calculate the length of your arms. Since the length of your leg may vary from that of other people, the arm span can accurately measure the right ball for you.

However, using this methhod might be a bit difficult (and require more time) as most people usually have more knowledge of their height than their arm span.
