15x10 for 3v3 feels tiny – are you using bigger pitches?

I’d start at 15x10 and only move it if the game is telling you there is a reason. It is meant to feel busy. Six players in a small area creates lots of touches, 1v1s, changes of possession and chances to score. If we make the pitch much bigger just because the first few games look crowded, we can take away some of what the format is trying to give them. That said, the guidance allows some flexibility, so I would not treat 15x10 as a magic number for every group. Try it for a few games. If the ball is genuinely never staying in play or the children cannot get any football going, add a little space and compare it. I’d change the pitch because of what the players need, not because it looks untidy to the adults.
