useful information about basketballs
Proper Indoor Basketball Size by Age and Gender:
Selecting the right basketball size is essential for player development, especially in youth and competitive settings.
For men ages 15 and up, the official size is a Size 7 basketball, which measures 29.5 inches in circumference and weighs 22 ounces. This is the standard used in high school, college, NBA, and FIBA men’s competitions.
For women and girls ages 12 and up, the proper size is Size 6, with a 28.5-inch circumference and 20-ounce weight. Size 6 is also often used by boys between the ages of 12 to 14.
For younger players ages 9 to 11, a Size 5 ball is recommended, measuring 27.5 inches and weighing around 17 ounces, ideal for building fundamental skills.
Children between 5 and 8 years old may benefit from a Size 4 ball (25.5 inches), while toddlers and beginners under 5 can start with a Size 3 mini ball (22 inches).
Using the appropriate ball size for each age group not only helps improve technique but also enhances confidence and enjoyment in the game.
Best Indoor Basketball for Top-Level Competition
When it comes to top-tier basketball competition, performance, consistency, and feel are everything. The current gold standard for elite play is the Wilson NBA Official Game Ball, which is used across all NBA games. Made from genuine leather, this ball is designed for professional-level performance, offering superior grip, bounce, and durability once broken in. It meets exact specifications for weight, circumference, and responsiveness, and is preferred by many pros for its consistency and feel on hardwood courts.
In college basketball, the Wilson NCAA Official Game Ball commonly known as the Wilson Solution or Evo NXT stands out as the preferred choice. Boasting advanced moisture wicking composite leather, it offers exceptional grip and a soft feel, perfect for the high-stakes action of NCAA play. I highly recommend opting for the Wilson. While it comes at a higher price, you'll be investing in top quality, and with proper care, it can last a lifetime.

If you're playing or coaching at the highest levels, any of these three—Wilson NBA Official, Wilson NCAA Evo NXT, or Molten BG5000—are trusted and proven options. Each delivers elite-level performance for serious athletes
How to Test the Inflation of a Basketball
Making sure your basketball is properly inflated is essential for consistent performance and ball control.
There are a few easy ways to check if your ball is at the correct pressure. The quickest method is the bounce test, simply drop the ball from about shoulder height onto a hard surface; it should bounce back up to approximately waist level. If it bounces lower, it's underinflated; if it bounces higher or feels rock hard, it's likely overinflated. This is an adequate check. You'll see officials doing this before most games.
Another common method is the hand feel test—press the ball gently with both thumbs. A properly inflated ball should feel firm with just a slight give.
For a more precision reading, use a ball pressure gauge by inserting it into the valve.
Regulation pressure for a men’s basketball is between 7.5 to 8.5 PSI, while women’s and youth balls usually fall between 7.0 and 8.0 PSI. Visually, a properly inflated ball should appear perfectly round without any flat spots or bulges.
To inflate correctly, use a pump with a needle, and be sure to moisten the needle before inserting it to protect the valve. Maintaining the right pressure ensures optimal bounce, grip, and playability.
