Basketballs for indoor and outdoor use
Materials
Indoor basketballs are typically made of full-grain or synthetic leather, which offers a superior grip and control. However, these balls can be expensive and require a break-in period to achieve optimal performance. On the other hand, outdoor basketballs are usually made of rubber, which is more durable and suitable for rougher surfaces. Rubber balls are also more affordable and easier to control, making them a popular choice for beginners.
Pricing
Indoor basketballs often fall within the price range of $60 to $100, with genuine leather balls being the most expensive. In contrast, decent outdoor balls can be found for as little as $15, making them a more budget-friendly option.
Durability
Indoor basketballs are delicate and can be easily damaged when used outdoors. The rough surfaces and environmental factors like dirt and moisture can quickly ruin an indoor ball. Outdoor basketballs, on the other hand, are designed to withstand harsher conditions and offer more flexibility, as they can be used indoors without sustaining damage.
Size
When choosing an indoor or outdoor basketball, size is an important consideration. Basketball sizes vary based on age, gender, and level of play. The official size for the NBA is 29.5 inches in circumference, with a diameter between 9.43 and 9.51 inches. For the WNBA, the ball is slightly smaller, with a circumference of 28.5 inches. In FIBA play, the ball size differs for men and women, with circumferences of 30.7 inches and 29 inches, respectively.
Recommendations
Several basketball brands offer models suitable for both indoor and outdoor use. The Molten BG3000, Spalding TF 250, Wilson NCAA, Nike Elite Competition, and Airball 'Black & White' are all examples of indoor/outdoor basketballs that provide a balance between performance and durability.

Youth basketball weights
Basketballs usually range in size from a few inches in diameter to extra-large balls nearly 2 feet (60 cm) in diameter used in training exercises. The official NBA basketball size is 29.5 inches in circumference, with a diameter between 9.43 and 9.51 inches, and a maximum weight of 22 ounces.
The weight of basketballs increases as the size increases. Youth basketballs are lighter to accommodate the players' sizes and skill levels. Using a basketball that is too big will make the ball harder to catch and control, and will negatively impact the player's performance, development, and enjoyment.
Youth basketball players can develop strength and mass through bodyweight exercises such as lunges, squats, and push-ups, without needing to use weights. It is important to emphasise proper form and safety over the weights being lifted. When youth athletes are physically and mentally ready to begin weight training, they should focus on total-body routines or "upper-lower" splits, with exercises such as barbell squats, deadlifts, overhead presses, barbell rows, bench presses, pull-ups, and dips.
Basketballs used in the NCAA are between 9.39 and 9.55 inches in diameter for men and 9.07 and 9.23 inches for women, with a maximum weight of 22 ounces for men and 20 ounces for women. In FIBA play, the rules state that the basketball must be inflated to a certain air pressure such that when dropped from a height of approximately 1,800 mm, it rebounds to a height of between 1,200 mm and 1,400 mm. The basketballs used in FIBA play have a circumference of 30.7 inches for men and 29 inches for women.
