What size yoga ball do you need to sit at your desk?
There are five standard sizes for yoga balls: 45 cm, 55 cm, 65 cm, 75 cm, and 85 cm. Once you have inflated the ball entirely, these measurements indicate its height. The most common exercise ball size is a 65 cm ball, suitable for people between 5’9″ and 6’2″ tall.
How To Sit On a Yoga Ball Correctly:
- It is essential to keep your feet flat on the floor and to distribute your weight evenly.
- Your knees should line up or be slightly higher than your hips and create an angle of 90 degrees or greater at the hips and knees (somewhat bent thighs pointing down).
- The body should be in a vertical line from the pelvis to the ears without any twisting. This alignment is usually obtained by lightly bobbing up and down.
How do I choose the right size exercise ball?
When buying a yoga ball, there are a few things you need to remember. Firstly, you want to buy a yoga ball from a reputable company. Yoga balls made by reputable companies are ergonomic and comfortable. They are made of material that ensures you won’t slide on your flooring. This will help prevent injuries.
Measure the distance between the floor and your knees to determine the correct size of an exercise ball for you. When you sit on the ball, your hips and knees should bend at a ninety-degree angle.
In addition to height, other factors determine ball size, such as your weight and flexibility. Once you apply weight to the exercise ball, the ball will deflate and sink a bit. Thi may cause injury if the ball drops too much and you are in the wrong stance.
Use the table below to find out what size exercise ball will be the most comfortable for you.
|Exercise Ball Diameter||A person’s Height|
|X Small- 45 cm (17 inches)||5.1–5.8 feet|
|Small- 55 cm (22 inches)||5.9–6.2 feet|
|Medium- 65 cm (26 inches)||6.3–6.7 feet|
|Large- 75 cm (30 inches)||6.8–6.9 feet|
|X Large- 85 cm (35 inches)||Not an easy size to find but ideal for people 7 feet and taller|
While the table above can be used as a general rule of thumb, choosing the right ball size for an office chair can be more challenging. When it comes to sitting at a desk, The University of Minnesota Extension recommends using an exercise ball that is one size larger. It may appear that the ball has deflated somewhat while you are sitting on it. Once the ball reduces, your working position changes. By using a slightly bigger ball, your position will stay correct for longer.
Comparing Yoga Balls and Office Chairs
For this section, we will take the average-sized yoga ball as well as the average-sized office chair.
The average yoga ball, once inflated, is 26 inches. On paper, you get more surface area on a ball than you do on a chair. With that in mind, there is no place for your arms to rest comfortably on a yoga ball. You also do not have a backrest which will take up some of the surface areas of the ball.
From a comfort point of view, a yoga ball is only comfortable for a short period. You will need to stand up, walk around for a little bit and move your muscles around not to become stiff.
A yoga ball does have benefits if you use it correctly. It helps with your posture and helps to tighten your core, which means you’ll work out while on the job. You can get the benefit of exercising your brain and muscles at the same time.
The average/standard office chair is between 17-20 inches wide. Even though a seat on a traditional office chair is smaller than a yoga ball, you still have more room to place your arms on a standard chair as they often have armrests attached. The backrest can also take up some of the surface areas from the chair.
A standard office chair’s design keeps your back up straight and helps take the load off your muscles when working. Your muscles can stay dormant, which means you are not using your muscles to hold yourself up. Whereas on the yoga ball, your muscles keep your posture correct, not the chair.
The height difference between the ball and an office chair will differ. It all depends on which size ball you get and the height you need your office chair to be for you to sit correctly at your office desk.
|Yoga Ball||Office Chair|
|The average size is 26 inches||The average size is between 17-20 inches|
|Does not have arm or backrests||Often comes with arm and backrests|
|It helps to tighten and strengthen your core||It helps ensure you do not overuse your muscles|
|Exercise balls typically have a weight limit of 250 pounds||A standard chair can handle between 250- 300 pounds|
