Yoga balls are an increasingly popular piece of sporting equipment. They also have ample surface area on which to advertise, which makes them a perfect choice for branded equipment. We thought it would be a good idea to give an insight into how these simple, yet effective, sporting products are made.
PVC Production
Most commonly, exercise balls are made out of a material called Polyvinyl chloride. Polyvinyl chloride, sometimes referred to as soft plastic vinyl, is a result of the polymerisation of vinyl chloride. For those of you who are perhaps less scientifically inclined, this essentially means that a bunch of a compound called vinyl chloride are joined together.
PVC Additives
Following this process of polymerisation, we have unmodified polyvinyl chloride. This is not suitable to use in the production of your promotional yoga ball, so additives are used to alter the product. There are many different additives used to create modified PVC, ranging from heat or UV stabilisers, to impact modifiers, to flame retardants.
To understand how material choices impact durability and performance, check out How it’s Made: Promotional Rugby Balls, where we break down the production process, including how additives and material modifications ensure high-quality custom rugby balls for branding and promotions.
Creating the Ball: Rotational Molding & Custom Printing
Once the modified PVC compound is mixed, the manufacturing process relies on a technique called rotational molding (rotomolding). Liquid PVC resin is poured into a hollow, spherical aluminum mold heated to high temperatures. As the mold rotates simultaneously along two perpendicular axes, centrifugal force spreads the liquid plastic evenly across the interior walls, ensuring uniform wall thickness and critical anti-burst strength.
After cooling, the ball is inflated, quality-tested for air retention, and prepared for custom branding. Logos and marketing artwork are applied using specialized screen printing or pad printing inks engineered to stretch alongside the PVC surface without cracking during inflation and heavy use.
What is the Biggest Yoga Ball Size Available?
When choosing branded fitness equipment, surface area and proper sizing matter. While standard promotional exercise balls range from 55 cm to 75 cm, the biggest standard commercial yoga ball reaches 85 cm (33.5 inches) in diameter, designed specifically for individuals over 6'2" (188 cm).
For specialized trade show displays, giant promotional events, or core stability training, custom oversized balls can reach 95 cm to 120 cm. Selecting the biggest yoga ball size gives your brand maximum logo visibility while comfortably accommodating taller users during corporate wellness campaigns.
| Yoga Ball Size (Diameter) | User Height Recommendation | Primary Use Case |
| 55 cm | 5'0" – 5'6" (152–167 cm) | Standard Fitness & Desk Seating |
| 65 cm | 5'7" – 6'1" (170–185 cm) | Most Popular Promotional Size |
| 75 cm | 6'2" – 6'8" (188–203 cm) | Tall User Training & Branding |
| 85 cm+ (Biggest Size) | 6'8"+ / Oversized Display | Maximum Surface Area Advertising |
Differences in Quality
The major difference in yoga ball quality comes from the thickness of the PVC. Cheaper, lower-quality yoga balls tend to be made of a thinner material. This makes them more prone to popping, which can be dangerous if you are sitting on them or performing an exercise. Thicker PVC tends to be more puncture-resistant, providing a more durable, anti-burst product.
Conclusion
Promotional yoga balls offer a versatile blend of functional fitness and high-impact brand visibility. By understanding the core manufacturing steps from PVC polymerisation and rotomolding to anti-burst wall testing, you can choose the right material thickness and sizing for your target audience. Whether you select a standard 65 cm model for corporate wellness initiatives or opt for the biggest yoga ball size available to maximize logo real estate at events, investing in quality construction ensures your brand remains durable, safe, and top-of-mind.
Frequently Asked Questions
What is the biggest yoga ball size available?

What material are promotional yoga balls made from?
Most quality exercise balls are made from durable, anti-burst Polyvinyl Chloride (PVC) combined with specialized plasticizers and stabilizers to ensure flexible, puncture-resistant performance.
How does anti-burst protection work on a yoga ball?
Anti-burst yoga balls are designed with thick PVC material walls that deflate slowly if punctured, preventing sudden popping and ensuring safety during heavy weight training or seating.
Can you print custom logos on the biggest yoga balls?
Yes, screen printing and pad printing techniques allow custom logos and branding to be applied to yoga balls of any size, including 75 cm and 85 cm models, creating high-visibility promotional equipment.
