Wilson JR.NBA Authentic In/Outdoor Basketball (7)
Tear up the local court and train in the gym the same day with the same ball. The Wilson JR NBA Authentic In/Outdoor is a basketball made of PU leather material in size 7, with the official NBA logo.
Since 2021, Wilson has been the official supplier of NBA game balls. This JR NBA Authentic carries that branding and is made to last on multiple surfaces.
PU leather with a bladder
The outside is made of PU leather material, suitable for both indoor and outdoor use without the ball wearing out right away. Inside there's a bladder — most outdoor balls don't have one — so the ball keeps a nicer bounce and doesn't go flat right away if it lands on something sharp.
Sticking to one surface extends its life
This ball works both indoors and outdoors, but if you keep switching between the gym floor and asphalt, it wears out faster. If you mostly play outside, count on about two outdoor seasons; if you only use it indoors, it lasts much longer. Don't leave it out in the rain or cold.
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 JR NBA Authentic In/Outdoor in size 7.
The official NBB size chart
If you play in a league, what counts isn't your age but your category — and sometimes your level too. This is the table from the Handboek Competities of the Dutch Basketball Federation (NBB), 2025-2026 season. Your age on 1 January determines which category you're in.
| 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.
