When it comes to basketball it’s easy to think that a one size fits all equipment strategy is a fine way to go. However things couldn’t be further from the truth. Equipment size and basketball sizes especially has a large impact on play. From safety to muscle memory, using the right size ball for practice and game play is an important factor to remember.
Using the wrong size ball can have a negative effect on the development of a child or youth’s technique. Muscle memory plays a key role in improving your proficiency at a sport and helps you make the right decisions in those split second moments.
I play basketball with my children and the difference between my 5 year old having fun playing and walking away crying is generally the ball size. If he tries to play with a regulation size ball he often gets hurt. But using a mini ball increases his confidence, gives him better control and allows him to play safely.

Team-play and low level competition are good things at this age but focusing on the fun that can be had while playing sports should be at the forefront of all games and activities.

Children under the age of 5 should focus on becoming proficient at rolling the ball across the floor in a straight line and throwing the ball with some precision to another child or adult. Catching from a gentle toss is good as well with the use of a soft-touch or thickly padded softball size ball. Do not use an actual softball as these are far too hard and can be dangerous to the child.
