How many players are on the ground, and what size is the oval at each age?

Question

Accepted Answer

From the AFL Junior Rules Handbook (ground sizes are length x width in metres):

Age	On the ground per team	Maximum squad	Ground size	Maximum ground
Under 9	9	12	85 x 65	100 x 80
Under 10	12	15	85 x 65	100 x 80
Under 11	12	15	115 x 75	130 x 90
Under 12	12	15	115 x 75	130 x 90

Age groups should be single years where possible, with a two-year span (Under 8, 10, 12, 14, 16, 18) as the second option.

Spectators stay on the outer side of the field of play, and only team-listed officials are allowed on the field.
