Wilson NBA Authentic In/Outdoor Basketball (7)
How close can you get to the official game ball without paying the price that comes with it? The Wilson NBA Authentic In/Outdoor is a replica of the official NBA ball, in size 7.
Wilson has been the official supplier of the NBA game balls since 2021. This Authentic version carries the official NBA logo and the signature of Commissioner Adam Silver.
Composite leather with Pure Feel Cover
The outer layer is high-quality composite leather with a Pure Feel Cover — which makes this replica feel hardly any different from the real game ball. The bladder has a sturdy valve, which provides an excellent bounce and a longer lifespan, even with heavy use.
Indoors and outdoors, with a little extra care
This ball is made for both the gym and the street, but is partly made of leather. So don't leave it outside after playing — good care noticeably extends its lifespan.
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 In/Outdoor in size 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.
