Picking the right size of basketball requires some knowledge of the sports. Which size of basketball you choose is going to be determined by your age, gender, and types of basketball courts.

1. Why is choosing the proper size basketball important?

Sing: “It is very important to pick the right basketball because playing with an incorrectly sized ball can have long-term negative effects on a player’s technique. When younger players use a larger basketball, they tend to compensate by shooting with both arms or dropping the shoulder, thus developing bad shooting habits.

Additionally, different leagues have various restrictions regarding the size, material, and colour of the basketball. So how to choose the right basketball? In my coaching experience, all primary schoolers will use size 5 balls, girls in middle school will use size 6 whereas boys will use size 7. Different sizes of basketball are made specifically for different age groups and genders.”

2. Are there any differences between indoor and outdoor  street basketballs?

Sing: “Absolutely! Budget-friendly basketballs are best to play outdoors and on street courts. Basketballs made with premium materials are prone to collecting dirt and dust, so they should be used for indoor playing.”

5.What are rubber basketballs?

Sing: “Rubber basketballs are designed for kids, suitable for outdoor and street court. They are equipped with a cover construction designed to perform well in all-round weather conditions and will be much more durable on rough surfaces, also bouncier than composite leather, however, this compromises the touch and feel.”


Pebbled rubber cover

Lightweight basketball

- Wizzy is a line of lightweight basketball- 18% lighter than other balls in the same size- Softer and lighter for beginner to practice shooting form- Size 5 Available

6. Which basketball is the best for indoor play?

Sing: “Most of the indoor basketball courts are made from polished hardwood which delivers good bounce while dribbling, as opposed to concrete floors. Microfibre basketballs offer better grip and feel than composite basketballs, making them a better choice for indoor play. But they are more prone to collecting dirt and dust, so this type of basketball is not recommended for outdoor or street courts.
