For a 12-year-old, the recommended basketball size is Size 6. This basketball has a circumference of 28.5 inches (72 cm) and weighs about 20 ounces (567 grams). Size 6 is suitable for boys and girls around the age of 12, providing a good balance of grip and control for young players.
For younger children or those who may have smaller hands, a Size 5 (27.5 inches in circumference and 17 ounces in weight) might be a better fit. However, as a 12-year-old, most players will find Size 6 the most appropriate choice for both practice and competitive play.
