Technical information

For a good bounce, how much should you inflate your basketball?

A basketball that is overinflated or underinflated will deliver a sub-par playing experience.
The recommended pressure is clearly marked on the ball by the manufacturer.
Ideally, you should use a pump with a pressure gauge for a more precise inflation.
At Tarmak, we recommend a pressure of 0.62 bar.
Enjoy your game!

What ball size to choose?

The ball size depends on the player's age and gender.
Size 1: From ages 2 and up
Size 3 to size 5: Girls or boys ages 4 to 6 / Baby basket under 7 age group (depending on levels and clubs)
Size 5: Boys and girls ages 7 to 10 / Under 9 and under 11 age groups
Size 6: Boys ages 11 and 12 / Under 13 age group
Size 6: Girls - Women of all ages over 11
Size 7: Boys ages 13 and up, and men.

What ball should you use?

If you want a very durable ball, go for a rubber ball. If you're looking for a ball with a good ball feel, choose a leather or synthetic ball.

What height basket should you choose?

The official height of a basketball basket is 3.05m (rim height).
If you want a basketball basket for your child, you need something that will grow with them.
For younger kids there isn't an official height so you can choose whatever suits them best.
Up to the age of 10, club baskets are set at 2.60m.
After the age of 10, both girls and boys play with 3.05m baskets.
