Quick Answer: Exercise Ball Size for 6-Foot Tall People
For someone who is 6 feet (72 inches) tall, you should use a 65cm or 75cm exercise ball.
- 65cm ball: Best for heights 5'9" to 6'2" - ideal if you're closer to 6 feet
- 75cm ball: Best for heights 6'0" to 6'5" - ideal if you're 6 feet or taller
When sitting on the ball, your knees should be at a 90-degree angle with your thighs parallel to the floor. This guide will help you choose the perfect size for your height and needs.
Why Exercise Balls Are Worth Your Time
Our lives are busy, especially around the holidays. This makes finding time for the recommended daily amount of exercise nearly impossible. Between work, school, kids, chores, and other activities, it can feel like there aren't enough hours in the day to get everything done. Even if you have the time, you may not be able to hit the gym and work out. The good news is you don't need an expensive gym or a lot of time to stay fit and become a better version of yourself!
The exercise ball is a great value-for-money equipment option that you can use in the comfort of your own home to exercise your entire body in a fraction of the time. With this exercise ball, you can get a simple yet effective workout that you can do any time of the day - before work, during your lunch break, or even between doing chores.
How to Choose the Right Exercise Ball
Exercise balls, also known as balance balls, stability balls, Swiss balls, yoga balls, birthing balls, or therapy balls, are a popular training accessory for everything from core and balance training to yoga and Pilates classes. But with so many options, which one is right for you?
Two Key Factors When Choosing an Exercise Ball
When choosing an exercise ball, there are two key points to consider:
1. Your Height & 2. Your Training Volume
Factor 1: Your Height
Determining the proper stability ball size for a fitness program starts with the user's height. Ideally, when sitting upright on a stability ball, your knees should be at a 90-degree angle and your hips should be in line with your knees. If your hips are lower than your knees are bent, the ball is too small - if your hips are slightly higher than your knees, the ball is too large.
The most popular size for group lessons is 55cm to 75cm, as most users are between 4'5" - 6'3". However, be sure to have several 45cm diameter stability balls for smaller users and several 85cm exercise balls for users over 6'3".
Complete Exercise Ball Size Chart
| Stability Ball Size | User Height Range |
|---|---|
| S size 38-45cm | <4'5" |
| M size 48-55cm | 4'5" – 5'1" |
| L size 58-65cm | 5'1" – 5'9" |
| XL size 68-75cm | 5'9" – 6'3" (Recommended for 6-foot tall) |
| XXL size 78-85cm | >6'3" |
For 6-foot tall people: The 65-75cm range is ideal. Choose 65cm if you're on the shorter end of 6 feet, or 75cm if you're taller or prefer a slightly higher seat.
Factor 2: Training Volume and Usage
Another consideration to keep in mind when choosing an exercise ball is how much you train or how often you use it. Stability balls are made of PVC material that varies in thickness or "gauge". If multiple different users intend to use the stability ball multiple times per week, a heavy-duty cellular material construction similar to the Trideer exercise ball is recommended.
Usage considerations:
- Light home use (1-2 times/week): Standard PVC is sufficient
- Regular home use (3-5 times/week): Choose thicker, anti-burst material
- Heavy commercial use (daily, multiple users): Professional-grade heavy-duty construction required
- Office chair replacement: Anti-burst, extra-thick material essential for safety
Choosing Your Color
Once you have determined the average height of the user and the volume of the exercise ball, you can choose the color you like. Trideer offers yoga balls in more than five colors and sizes.
After selecting the right exercise ball mix for your facility and training program, protect your balls with proper storage and inspection.
Storage of Exercise Balls
The yoga exercise ball by itself can take up a lot of floor or closet space, but adding dedicated equipment storage racks will maximize your training or storage space. You can also deflate it to reduce storage space when not in use.
Storage tips:
- Store away from direct sunlight and heat sources
- Keep away from sharp objects
- Use a storage rack to save floor space
- Deflate for long-term storage (over 3 months)
- Store in a cool, dry place
Exercise Ball Inspection and Maintenance
Inspecting exercise equipment is important to ensure that all parts are in working order, free from hazards, and are in functional and aesthetic condition. Here are a few things to look out for when inspecting a stability ball:
Does It Hold Its Shape?
This could indicate a slow air leak, or a deformity depending on the environment or usage.
What to check: Press the ball firmly - it should bounce back quickly and maintain its round shape.
Is It Inflated to the Recommended Diameter?
Over- or under-inflation will shorten the life of the stability ball.
How to check: Measure the diameter with a tape measure. For a 65cm ball, it should measure 65cm (25.6 inches) across when fully inflated.
Are There Any Dents, Scratches, Scuffs or Cuts on the Exterior?
Normal wear and tear develops over time and creates structural holes.
What to do: Replace the ball if you notice any cuts, deep scratches, or areas that look thin or discolored.
Track When the Unit Is Put Into Service
In heavy commercial use environments, the stability ball should be replaced every 9-12 months.
Replacement schedule:
- Light home use: 3-5 years
- Regular home use: 2-3 years
- Heavy commercial use: 9-12 months

Frequently Asked Questions
What size exercise ball should I get if I'm 6 feet tall?
For someone who is 6 feet (72 inches) tall, a 65cm or 75cm exercise ball is recommended. Choose 65cm if you're closer to 5'11"-6'0", or 75cm if you're 6'0"-6'2" or prefer a slightly higher seat. When sitting, your knees should be at a 90-degree angle.
How do I know if my exercise ball is the right size?
Sit on the ball with feet flat on the floor. Your knees should be at a 90-degree angle, with thighs parallel to the floor. If your knees point upward, the ball is too small. If your feet don't touch the floor comfortably, it's too large.
Can I use a 65cm ball if I'm exactly 6 feet tall?
Yes! A 65cm ball works well for people who are 5'9" to 6'2". If you're exactly 6 feet, a 65cm ball is a great choice. You can also try a 75cm ball if you prefer a slightly higher seat or plan to use it as an office chair.
What's the difference between 65cm and 75cm for a 6-foot person?
Both sizes work for 6-foot tall people. A 65cm ball provides a lower seat (better for exercises), while a 75cm ball provides a higher seat (better for office chair use or if you have longer legs). Try both if possible to see which feels more comfortable.
How much should I inflate my exercise ball?
Inflate to the stated diameter (65cm or 75cm). The ball should be firm but have slight give when you press it with your palm (about 1-2 inches of compression). Over-inflation can cause bursting; under-inflation reduces effectiveness.
Can a 6-foot tall person use a 55cm ball?
A 55cm ball is too small for someone 6 feet tall. It's designed for people 4'5" to 5'1". Using a ball that's too small will cause your knees to be higher than your hips, leading to poor posture and reduced effectiveness.
Conclusion: Finding Your Perfect Exercise Ball Size
Choosing the right exercise ball size is essential for safety, comfort, and effectiveness. For 6-foot tall people, a 65cm or 75cm ball is the ideal choice, depending on your specific needs and preferences.
Key takeaways:
