How to make a team have player limit?

I have searched this up and everything and i can't find a answer, but how would i make it so that only a certain amount of players can be on a team?

First, find how many players you want on a team. Then count how many teams there are. Change the game's max players on a server so that when divided by the teams will get the number of max players in a certain team. Roblox will automatically place players in a team. Otherwise, Explain your question in detail. This is one way to do so.
