Quick Tip: Find the perfect yoga exercise ball size for your height and workout needs with our comprehensive guide.

Whether you’re craving a spinal release or a challenging ab workout, a yoga ball is the perfect prop for targeting core muscles, strength training, pilates, posture improvement, and deep stretching.

But when you’re on the hunt for the right stability ball, it can be difficult to sort through all the sizes and options out there. You don’t want something so small that it deflates under your weight, nor something too large to comfortably sit on or stretch over.

This guide will help you figure out the perfect size exercise ball for your home workouts and post-yoga stretches.

What is a stability ball?

Also called a yoga ball, swiss ball, or fitness ball, stability balls are essentially soft plastic exercise balls designed for physical therapy, core strengthening, and weight training.

Depending on the ball size and amount of air pressure, exercise balls engage whole muscle groups for more stability and tone. The unstable surface fires up your core muscles as well as smaller microfiber muscles.

What size yoga ball should I buy?

Choosing the right ball size is key for a successful swiss ball workout. Exercise balls are sold based on the diameter of the ball when it’s fully inflated. There is no “standard size”. Instead, the right size is based off your height and use for the ball.

The most common exercise ball size charts are:

  • Extra Small (30 cm/12″)
  • Small (45 cm/18″)
  • Medium (55 cm/22″)
  • Large (65 cm/26″)
  • Extra Large (75 cm/30″)

Now, use this chart to match your measurements with the correct ball height.

Your HeightRecommended Ball Size
4’6” or shorter30 cm/12"
4’6” to 5’45 cm/18"
5’ to 5’5”55 cm/22"
5’6” to 6’2”65 cm/26"
6’2” or taller75 cm/30"

You can use a yoga ball for:

Yoga and stretching:

As a yoga prop, a stability ball helps you get a deeper stretch without risking overextension. You can recline backwards on the ball or use it to aid in more advanced poses such as Scorpion pose. It can even be held as an added weight and balance challenger for yoga exercises. These soft inflatable props can be integrated into nearly any pose to make it easier or more challenging. A balance ball is a valuable tool for any yogi seeking to improve their balance, core strength, and flexibility.

Strength training:

Using an exercise ball in body weight or dumbbell exercises can help you get a full body workout. While certain movements like a pectoral fly or “skull crusher” tricep dip typically target only the arms, a stability ball adds in the legs and core. Essentially, the inflatable ball acts like a workout bench with some “give”. As your body sits or lays on the squishy ball, small muscle fibers are challenged to stabilize and hold you in place.

Core workouts:

Perhaps the most popular use of an exercise ball is in ab workouts. As long as you have the right size stability ball (which we’ll explore below), you can use the ball to support your back or legs as you try out a range of different core strengthening exercises. You’ll feel every part of your abs and obliques engaging (and maybe even shaking) as you try to stay stable atop the soft base.

Desk chair replacement:

If you want better posture and a mild core challenge while working at the computer, you can also use these inflatable workout balls as a replacement for your desk chair. The right size stability ball will allow you to sit evenly and comfortably with your feet flat on the floor and spine straight.

How to Choose the Correct Size Yoga Ball

An exercise ball is only comfortable to use if it has the proper dimensions for supporting your body. The perfect ball size will allow you to sit up straight with your feet flat on the floor, knees bent at a 90 degree angle, and your thighs parallel to the ground.

You can find the ideal size yoga ball with two different measurements: either use your height or measure the ball size by wall sitting and marking where the ball would ideally land beneath you. To do this:

  1. Stand with your back touching a wall
  2. Slide down into a wall sit with until your hips and knees are at a perfect 90 degree angle
  3. Use a pencil to mark on the wall just beneath your tail bone
  4. Use a tape measure to measure the height from the floor to your pencil mark. This is the correct ball height for you.

*Remember that when you sit or lay on the ball, it will naturally compress downward. If you are in between sizes or have a slightly deflated ball, size up to ensure that the proportions are correct.

Exercise Ball Size and Pregnancy; A Guide for Moms to Be

Selecting the Right Size When Expecting

Pregnancy brings about significant changes in your body, affecting your balance and comfort. Incorporating an exercise ball into your routine can be a great way to keep active and prepare for giving birth. However, it’s important to remember that not all sizes are suitable during pregnancy.

Opting for a slightly larger ball is often more comfortable when pregnant. This size allows you to sit with your knees positioned lower than your hips, promoting good posture and reducing strain on your lower back. For most expectant mothers, a ball measuring around 65 cm to 75 cm in diameter is recommended, especially as you progress into the second and third trimesters.

Safety Precautions for Pregnant Users

Safety is key when using an exercise ball while pregnant. Always ensure the area around you is clear of any potential obstacles that may lead to accidents. Use the ball on a carpet or non slip surface to prevent slipping. It’s also advisable to have a chair or stable surface nearby for support when getting on or off the ball.

Incorporating an exercise ball into your pregnancy routine can not only help maintain fitness but also assist in easing labor and delivery. Before beginning any new exercise routine while pregnant, it is important to seek guidance from your healthcare provider. They can offer tailored recommendations, considering your health status and the progress of your pregnancy.

Mistakes to Steer Clear of When Using Exercise Balls

Selecting the Incorrect Size

A major blunder many individuals make is picking the wrong size of exercise ball. If the ball is too small, sitting comfortably becomes a challenge. Your knees end up higher than your hips, potentially causing strain on your back. On the other hand, if it’s too large, maintaining balance and control can be a struggle.

Over or Under Inflation

Another common mistake is failing to inflate the ball to its proper size. An under inflated ball diminishes the effectiveness of exercises as it lacks ample resistance. Conversely, over inflating can lead to a overly firm ball, heightening the risk of bursting. Always use a tape measure to verify the ball’s height when fully inflated.

Disregarding Weight Limits

Each exercise ball comes with its own weight limit that should not be ignored for safety reasons. Exceeding this limit could result in the ball bursting during use. It’s essential to always refer to product specifications regarding weight limits to ensure a safe workout routine.

By steering clear of these typical errors, you can safely reap the rewards of using an exercise ball. Remember, choosing the right size and ensuring proper inflation are crucial for a successful and secure workout experience.

Key Takeaways: The Right Exercise Ball Size is Based of Your Height and Usage

Balance balls are awesome for a range of activities that improve your posture, balance, spinal health, and muscular strength.

Standard sizes are based off of your height to allow you to comfortably sit with your legs at a 90 degree angle and feet flat on the floor. These dimensions will allow a full range of motion whether you’re back-bending over the ball, bracing yourself for a core workout, or placing it beneath your feet in a lunge.

A larger or smaller ball will change the intensity of your workout. When in doubt, a larger ball with a little less firm inflation is best for beginners. A smaller ball with more air will challenge more muscles.

Whether you want a yoga ball to compliment your practice or get some spinal relief while you work, stability balls are affordable additions to your routine.

Namaste!
