Essential Gear

Basketball Shoes

High-top or mid-top shoes provide ankle support on hard courts. Look for non-marking rubber soles and good cushioning in the heel and forefoot.

Est. $40 โ€“ $120

Basketball

Size 5 for younger kids, Size 6 for U12 girls and middle school, Size 7 for older boys. Rubber outdoor balls are fine for driveways; composite leather for gym use.

Est. $20 โ€“ $60

๐Ÿฉณ

Athletic Shorts

Loose-fitting shorts with a comfortable waistband. Most leagues provide game shorts; these are for practice. Moisture-wicking fabric keeps players comfortable.

Est. $15 โ€“ $35

Athletic Crew Socks

Cushioned crew-length socks reduce blisters and provide extra comfort on hard floors. Avoid ankle socks โ€” they offer no protection under high tops.

Est. $8 โ€“ $15

Parent's Cheat Sheet

What just happened?

Official Wording

Illegal personal contact that disadvantages an opponent.

Parent Translation

Your kid pushed, grabbed, or bumped into the other player. 5 fouls and they're out for the game (some youth leagues allow 6). Common at every level โ€” even NBA stars foul out.

Parent guide

What does my child need for their first basketball season, and what are the rules I will hear about?

Short answer

For a first season you need court shoes, a comfortable athletic top and shorts (or the team uniform your league provides), athletic socks, and a water bottle. A ball for practice at home is helpful. The must-have items on this page add up to about $103โ€“$272. Most youth basketball is played indoors, so shoes should be meant for a hard court and have non-marking soles.

How youth basketball is set up

Expect practices that focus on dribbling, passing, and shooting form, then short games. Younger age groups often use smaller balls, lower baskets, or fewer players on the court, and some leagues do not use a shot clock.

Rules, court setups, and game length are set by each league, so ask your coach what applies to your child. Coaches often rotate players through positions so everyone learns the whole game.

Common violations, explained simply

Referees whistle a handful of things again and again. Knowing them takes most of the confusion out of a first game.

  • Traveling: taking too many steps without dribbling. The fix is to dribble before moving the feet.
  • Double dribble: dribbling, stopping, then dribbling again, or dribbling with two hands at once.
  • Backcourt: bringing the ball back across half-court after the team has crossed it.
  • Personal foul: illegal contact, such as pushing or grabbing. Players have a limit before they are out of the game, and the limit varies by league.
  • Out of bounds: the last team to touch the ball before it leaves the court loses possession.

Safety basics

Court shoes with good ankle and heel cushioning help on hard surfaces. Check the fit regularly, because kids outgrow shoes quickly.

Mouthguards and knee pads are optional in many leagues. Ask what yours requires. Follow your league and your doctor for any injury questions.

By age and level

Ages 5โ€“8
This site lists a size 5 ball for this range. Many programs focus on fun, ball handling, and basic shooting. Confirm ball size and rules with your league.
Ages 9โ€“12
This site lists a size 6 ball for girls, and boys move to a larger ball around 12. Games become more structured, with more positions and rules.
Ages 12 and up
Boys typically move to the size 7 ball. Shoe fit and ankle support matter more as play gets faster and more physical.

Common mistakes

  • Wearing running shoes on court. Court shoes give better support and grip for quick side-to-side moves.
  • Buying shoes that are too big "to grow into", which can cause slipping and blisters.
  • Buying a full-size ball for a young player. Use the size recommended for your child's age group.
  • Reading every whistle as a bad call. Many early-age violations are teaching moments, not penalties against your child.
  • Skipping the water bottle. Indoor gyms get warm and kids sweat more than they think.

Frequently asked questions

What basketball size does my child use?

This site lists size 5 for ages 5โ€“8, size 6 for ages 9โ€“12 (girls), and size 7 for boys 12 and up. Leagues set their own standards, so check with yours.

What does "traveling" mean?

It means a player moved with the ball without dribbling, usually by taking too many steps. It is very common in youth games.

How many fouls before a player is out?

It depends on the league. Many use five personal fouls; some youth leagues allow six. Ask your coach.

Do kids need knee pads or a mouthguard?

Usually these are optional, but a league may require a mouthguard. Ask before you buy.

Sources

Rules and requirements differ by league. When a source and your league disagree, follow your league.
