Most games (i.e. High School and Adult) are played with a size 5 ball, but a size 4 ball is also suitable, especially for an 8 year old
I believe they should be playing with a size 5 ball
A size 4 probably
Typically for that age girls use the womens size or 28.5.
The netball post for 11 year olds is about 3 metres in Australia.
10 feet official size ( 3.05 metres)should be the right size for her/him if you need to change the sizing personally would go with 9 feet.
As a guitar teacher I can say yes, a 12 year old should play a full size guitar.
If you are at primary school, it depends what year the school let's it. I started when i was in year four x
mabye get her involed in an club.
if you want them to get proper practice it should be 10ft
you could search the internet for the rules and let them watch netball games on you tube. And if they are in year 6 or bellow you can let them play in school netball.
netball was invented in 1895

Netball was invented in 1892 but was called Women's Basketball not Netball.
No matter what age we all have the same height and it is about 9 inch.
