Wilson NBA Authentic Series Rubber Outdoor Basketball Size 5, 6 & 7
Looking for an outdoor ball that isn't worn out after one summer? The Wilson NBA Authentic Series is a rubber outdoor basketball, in sizes 5, 6 and 7.
Since 2021, Wilson has been the exclusive supplier of the official NBA game balls. This Authentic Series carries the Wilson and NBA logos and is built specifically for outdoor play.
Rubber Tackskin cover for concrete and artificial turf
The rubber Tackskin cover is made for hard and rough surfaces like concrete and artificial turf. The ball holds its air pressure well, so it needs pumping up less often than a cheaper rubber ball.
Built to stay outdoors
Rubber is the material that lasts longest on the street. If you also want to play indoors, this ball feels harder in your hand on a gym floor than an indoor basketball — for that, choose a composite leather or microfiber ball.
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 NBA Authentic Series in sizes 5, 6 and 7.
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 improves your training more 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.
