What Size Workout Ball is Right for You?

Not sure what size workout ball is right for you? This quick guide will help you choose the perfect size ball for your fitness needs.


The right size of workout ball is essential for getting the most out of your exercise. It is not only important for comfort and form, but it also provides the body with a good range of motion, which in turn helps to increase strength and flexibility. When considering the type of workout ball to use, there are a few things to consider: size, material, weight capacity and style.

The size of a workout ball is usually determined using one’s height as a baseline. As a general rule of thumb, when seated on an exercise ball it should be around hip height (it should reach the crease between your hip and thigh). When standing on an exerciseball it should reach around mid-thigh. There are many helpful sizing charts available online that account for height and weight to help you find the correct fit for your body type.

It’s important to opt for one made from strong material such as anti-burst PVC that can handle your weight when positions become more dynamic. Finally, consider two different styles – an inflatable or non-inflatable version depending on preference or mobility level. With these pointers in mind, make sure you take time to research and select the right size workout ball for you!

Benefits of Using a Workout Ball

Using a workout ball during your exercise routine can be a great way to improve your balance and strengthen your core muscles. It can provide support to help maintain proper form while performing exercises, as well as add an extra element of challenge by introducing an unstable surface. When you are using a workout ball, you engage more areas of muscle activation as your body has to work harder to keep control. The benefits of using a workout ball include:

-Increased flexibility and joint range of motion
-Developing improved posture and balance
-Activating more muscles than traditional exercises
-Enhancing sports performance and endurance
-Enhancing core strength and stability
-Providing additional protection for the spine by cushioning it during exercise

Types of Workout Balls

Working out with a workout ball can help improve flexibility and core strength, as well as improve overall posture. There are a range of sizes available, from small stability balls to large exercise balls. Knowing what size is right for you can help you make the most out of your workout. Let’s explore the different types of workout balls and find out which one will be the best fit for you.

Stability Balls

Stability balls, also referred to exercise balls, Swiss balls, balance balls, fitness balls and physio balls, are highly versatile and provide an effective means of increasing body strength and overall health. These large air-filled balls vary in size to accommodate a range of heights from 4’9”-7’ or 135cm-195cm. When selecting the right size ball for you it is important to choose one that fits your height properly and meets your fitness goals.

Each size stability ball provides a different level of challenge depending on your weight, height, and workout level. Generally the rule of thumb is less heavy and shorter individuals should choose smaller sizes while larger people should go for a bigger ball. Below is a chart that recommends the optimal ball size for different types of users.

Stability Ball Sizes (in cm):
-Small (45 cm): 4’9″ – 5’4″
-Medium (55 cm): 5’5″ – 5’11”
-Large (65 cm): 6′ – 6’6″
-Extra Large (75 cm ): 6’7″ – 7′

Balance Balls

Balance balls, also known as swiss, physio, or stability balls, are a cardio and balance tool usually made of durable rubber that come in multiple sizes. Working out with a balance ball can provide increased strength and mobility training, improve muscular control (i.e., proprioception), and even reduce injury risk by activating more muscles than other exercises. Balance ball exercises are particularly efficient for total body strength training programs since most workouts focus on multiple muscle groups at once.

Sizing is important when selecting a balance ball since using one that’s too small may cause slouching or an unstable workout and one that’s too big may be challenging to use. A good gauge for proper sizing is to measure the height of the user while standing against a wall and then choose a ball which brings your thighs parallel to the ground when you’re sitting on it. Size guide as follows:
-45 cm/18 inches – For individuals up to 5 ft tall.
-55 cm/22 inches – For individuals between 5 ft 1 in – 5 ft 8 in tall
-65 cm 26 inches – For individuals taller than 5 ft 8 in

Medicine Balls

Medicine balls can be used for a wide range of exercises like squats, wall tosses, ab twists and more. They are usually 6-18 inches in diameter and range from 2-30 pounds depending on the intensity of your workout. Medicine balls are slightly bouncy and if you drop them on the floor it won’t cause damage to them.

Medicine balls come in textured or smooth surfaces. Textured medicine balls provide a better grip which makes them ideal for throwing and passing drills. Smooth medicine balls are better suited for ab exercises as they provide less friction against the skin, which prevents discomfort and possibility of scrape marks due to excessive friction.

Medicine balls also come in different shapes – round, octagonal (8 sides), pentagonal (5 sides) and hexagonal (6 sides). Depending on the exercise you’re looking to do, a different shape of ball might be best suited for it. For instance, an octagonal ball has 8 points that allow you to use your feet more accurately when performing abdominal exercises while the round one is best used when performing throws or passing drills since there will be no points creating discomfort when hitting with your hands or feet

How to Choose the Right Size Ball

Exercise balls have become increasingly popular for their versatility and effectiveness as part of a fitness routine. However, choosing the right size ball is important in order to optimize the effectiveness of your workout. The right size of ball can help you maintain proper form and posture while you exercise and prevent injury. Let’s look at the different factors to consider when choosing the right size ball for your fitness goals.

Measure your Height

In order to select the correct size exercise ball, you will need to measure your height and compare it to the guidelines provided by ball manufacturers for determining the size of ball that is best suited for your physical profile.

Your height will determine the diameter of the ball recommended. As a general rule, if you are shorter than 5′ 4″, it is recommended that you use a 55cm exercise ball; 5’4″ -5’11”, use a 65cm exercise ball; 6’0″ or taller, use a 75 cm exercise ball. For proper back support and body positioning during workouts, it is important that you choose an appropriate sized exercise ball based on your height.

If in doubt regarding which size would be best for you, always err on the side of caution and select a larger sized ball over a smaller one as having too small of an exercise ball can be uncomfortable – but not having one big enough can excessively strain neck and back muscles.

Consider your Weight

When people are deciding which size fitness ball to purchase, they should consider their weight. A bigger ball is a better choice for individuals who weigh more than 250 pounds, while a smaller ball is preferable for individuals who are lighter. To decide what size would be most suitable, people should consult the chart below.

Ball size:
-45 centimeters: People weighing up to 90 pounds
-55 centimeters: People weighing 91 – 200 pounds
-65 centimeters: People weighing 201 – 260 pounds
-75 centimeters: People weighing 261 – 300+ pounds

It’s important to note that all exercise balls don’t come in all sizes, so shoppers may have to shop around depending on their weight and the other criteria on their list. Ultimately, shoppers should ensure that no matter what size ball they choose, it allows them to keep their feet flat on the floor when sitting on it so that they can perform exercises properly and safely.

Consider your Exercise Goals

Choosing the right size exercise ball is important for optimal performance and injury prevention. If your exercise ball is too big, it can be difficult to maintain form and balance during a workout, increasing your chances of injury. On the other hand, if your exercise ball is too small it won’t be supportive enough, which can lead to back or neck pain.

When selecting an exercise ball for your workouts, consider the following:
– Your height: The most important factor in determining what size resistance ball you need is your height. To ensure you select the optimal size users should be seated on an appropriate sized ball with their hips and knee bent at 90-degree angles. For a proper fit all four points of contact – both feet flat on floor, buttocks and lower back – should make contact with the exercise ball.
-Your Exercise Goals: If you’re using an exercise ball primarily for stability exercises, such as Pilates or core work than choose a smaller sized ball that will allow you to remain still and steady while using correct form. However if balance activities are part of your routine or if you plan use the workout equipment do so regularly then choose a larger sized ball which will offer more support comfortably over time in addition to increased flexibility when performing dynamic exercises such as lunges or squats .
-Your Environment: Think about where you plan on doing most of your workouts before deciding which size fit best for you; if space is an issue than a smaller size may work best for those who must conduct their fitness routine inside a limited area such as in-home gym room


In conclusion, deciding what size workout ball is right for you will depend on your body size and how comfortable you feel sitting and performing exercises on it. Balls come in different sizes, so be sure to measure your height before deciding which one to buy. As a general rule, taller people are better suited for larger balls because it takes more effort to sit upright on them. Smaller people should consider using a smaller ball so they don’t have to stretch too far. Always remember that the goal is to be comfortable and safe when using an exercise ball— comfortability will give you the confidence that you need in order to reach your fitness goals!
