The Complete Sizing and Brand Guide
Everything you need to know about picking the right RG ball for training and competition
Whether your gymnast is about to buy their very first ball or upgrading to a competition-grade model, choosing the right rhythmic gymnastics ball matters more than most parents realise. The wrong size affects technique. The wrong material affects grip. And an unapproved ball can mean disqualification at competition.
This guide covers everything — sizes, materials, brands, FIG approval, care tips and what to look for at every level.
What size rhythmic gymnastics ball do I need?
Rhythmic gymnastics balls come in two main sizes, determined by the gymnast's age and competition level.
Junior balls (15–17 cm)
Junior rhythmic gymnastics balls measure between 15 cm and 17 cm in diameter. They are designed for younger gymnasts — typically those under 10 years old or competing at preliminary and development levels. The smaller diameter and lighter weight make them easier for small hands to control during rolls, throws and catches.
If your gymnast is aged 7 or younger, a 15–16 cm ball is usually the right choice. Gymnasts aged 8–10 may use a 16–17 cm ball depending on hand size and what their coach recommends.
Senior balls (18–18.5 cm)
Senior balls measure 18 cm to 18.5 cm in diameter and weigh at least 400 grams. This is the standard size for all gymnasts competing at regional level and above, and it is the only size permitted under FIG (International Gymnastics Federation) regulations for senior competition.
Once a gymnast moves beyond beginner level — usually around age 10–11 — they should transition to a senior-sized ball. Training with the correct size from an early stage builds the muscle memory and handling skills needed for competition.
Quick sizing reference
| Age / Level | Ball diameter | Ball weight | When to use |
|---|---|---|---|
| Under 7 / beginner | 15–16 cm | ~300 g | First ball, recreational classes |
| 8–10 / development | 16–17 cm | ~350 g | Club training, first competitions |
| 11+ / regional and above | 18–18.5 cm | 400 g minimum | All serious training and competition |
Tip: If your gymnast is between sizes, go with the larger ball. It is better to grow into the competition size than to develop habits with an undersized ball.
What are rhythmic gymnastics balls made of?
Modern RG balls are made from high-quality rubber or synthetic rubber compounds. The material needs to achieve a specific balance: enough grip that the ball does not slip during body rolls, enough bounce for controlled throws, and enough durability to withstand daily training on competition carpet.
The surface finish varies by model:
- Uni-colour / matte — Classic solid colours with a smooth rubber finish. Good grip, understated look. Popular for training.
- Metallic — A fine metallic powder is embedded into the rubber surface, creating a reflective sheen. Sasaki's Metallic and Magnetic lines are well known for this finish.
- Glitter — Glitter particles are mixed into or applied onto the rubber. Pastorelli's Glitter High Vision balls are among the most popular in this category.
- Galaxy / gradient — Multi-colour effects that blend two or more tones across the ball's surface. Stunning under competition lighting.
The finish is mostly cosmetic — all finishes from reputable brands offer similar grip and performance. Many gymnasts choose a ball colour that complements their leotard and music for a cohesive presentation at competitions.
Which brand should I choose?
There are five major brands in the rhythmic gymnastics ball market. Each is trusted at the highest levels of the sport, and the choice often comes down to personal preference, feel and budget.
Sasaki
Sasaki is a Japanese brand with a long history in rhythmic gymnastics. Their balls are known for excellent grip and distinctive colour options — the Meteor, Aurora and Magnetic lines feature striking metallic and colour-shift effects. Sasaki balls measure 18.5 cm (senior) and are FIG-approved. They sit at the premium end of the price range but are a favourite among competitive gymnasts worldwide.
Pastorelli
Pastorelli is an Italian brand and one of the most widely used in RG globally. Their High Vision ball range is a staple at competitions — available in uni-colour, glitter and shaded glitter finishes. Pastorelli balls are known for their reliable grip, consistent bounce and excellent shape retention. The 18 cm senior balls and 16 cm junior balls are both FIG-approved where stated.
Chacott
Another Japanese brand, Chacott produces balls with a reputation for precision and quality. Their rubber compound offers a distinctive feel that some gymnasts prefer. Chacott balls come in a wide range of colours and are FIG-approved at competition sizes.
Amaya
Amaya is a Spanish manufacturer offering solid competition-grade balls at a slightly lower price point. Their 18 cm FIG-approved balls are a popular choice for gymnasts who want quality without the premium price tag of Japanese brands.
Venturelli
Italian brand Venturelli produces the Star Line and Star Line Elite balls — both FIG-approved at 18 cm. Known for vibrant colours and a good balance of grip and durability, Venturelli balls are a strong mid-range option.

Does my gymnast need a FIG-approved ball?
If your gymnast competes at regional level or above — including British Gymnastics national events, European Championships or any FIG-sanctioned competition — then yes, a FIG-approved ball is required. Using a non-approved ball can result in a deduction or disqualification.
For recreational classes, school gymnastics or very early development levels, FIG approval is not necessary. A good-quality junior ball from any reputable brand will be fine.
When shopping, look for "FIG approved" or "FIG certified" in the product description. All senior-sized balls from Sasaki, Pastorelli, Chacott, Amaya and Venturelli are FIG-approved, but not every colour or junior size carries the certification — always check.
How to care for your rhythmic gymnastics ball
A good ball is an investment, and proper care extends its life significantly.
Storage: Always store your ball in a protective ball cover when not in use. This prevents scuffs, scratches and colour transfer from other items in your kit bag. Store at room temperature (roughly 3°C to 25°C) and avoid leaving the ball in a hot car or direct sunlight.
Inflation: Only inflate your ball using the hand pump recommended by the manufacturer. Before inserting the needle, apply ball smoother (a silicone-based grease) to the valve needle — inserting a dry needle can damage the valve and void your warranty. Do not over-inflate; the ball should match its stated diameter and give very slightly when pressed.
Deflation for storage: When storing your ball for more than a few days, deflate it slightly. This reduces pressure on the seams and helps the ball maintain its shape over time. Never store or transport a ball completely deflated.
Cleaning: Wipe the ball with a soft cloth dampened with warm, soapy water. Avoid solvents, alcohol-based cleaners or abrasive cloths. Dry thoroughly before returning it to its cover.
Surface use: Only use your RG ball on proper rhythmic gymnastics carpet. Using it on rubber floors, linoleum, concrete or outdoor surfaces will damage the surface finish and void the warranty.
What else do I need to buy with a ball?
A few essential accessories to consider alongside your ball:
- Ball cover — Protects against scratches during transport. Most brands sell covers in matching or neutral colours.
- Ball pump — Use the pump from the same brand as your ball where possible. Sasaki balls should be inflated with a Sasaki pump, and so on.
- Ball smoother / valve grease — A small tube of silicone grease to protect the valve during inflation. Inexpensive but important.
