Wilson WNBA Authentic Series Outdoor Basketball (6)
Conquer the outdoor court with the official women's league size. The Wilson WNBA Authentic Series is an outdoor basketball in size 6 — the official size for women and the intermediate size for men.
Wilson is the official ball of the WNBA. This Authentic Series brings that look to the outdoor court, with the same Tackskin construction as the outdoor balls from the NBA line.
Tackskin cover with an extra cushion layer
The Tackskin Cover has a cushion layer that provides grip, even when the weather isn't cooperating. That makes the ball comfortable in your hand in rain or cold, when a smooth ball would slip right out of your hands.
Built for daily outdoor use
This ball is made to take a beating: the rubber construction holds up on rough outdoor surfaces and doesn't lose its grip after a few weeks of play. If you want to play indoors, choose an indoor or in/outdoor basketball.
What size basketball do you need?
If you play recreationally, this is the rule of thumb:
- Size 7 — men and boys from around fifteen
- Size 6 — all women and girls, and boys from about twelve to fifteen
- Size 5 — kids up to about twelve
Torn between sizes for a growing player? Go smaller. With a basketball that's too heavy, a kid learns to shoot from the shoulder instead of the wrist, and that technique is hard to unlearn.
We carry the WNBA Authentic Series in size 6.
The official NBB size chart
If you play in a league, it's not your age that counts but your category — and sometimes your level too. This is the table from the Handboek Competities of the Dutch Basketball Federation, season 2025-2026. Your age on 1 January determines which category you fall into.
| League play | Ball size | Hoop height |
|---|---|---|
| U8 regional | Size 4 | 2.60 m |
| U10 regional | Size 5 | 2.60 m |
| U12 regional | Size 5 | 2.60 m |
| U12 national | Size 6 | 2.60 m |
| U14 regional and national | Size 6 | 3.05 m |
| Men's U16 regional and national | Size 7 | 3.05 m |
| Women's U16 regional and national | Size 6 | 3.05 m |
Three things stand out. U12 depends on the level, not on age: regionally you play with a size 5, nationally with a size 6. U16 splits by gender — men move up to size 7, women stay at size 6. And from U18, the regular size simply applies: 7 for men, 6 for women.

Pressure check
The right pressure is 0.5 to 0.6 bar (7 to 9 PSI). At the right pressure, every ball bounces the same, and that does more for your training than any drill.
No pressure gauge? Use the bounce test: hold the ball straight out beside you at shoulder height and drop it. If it bounces back to about your hip, the pressure is right. If it comes up higher, let out some air; if it stays lower, pump in a little more.
