What is the maximum Summoner level in League of Legends?

I just wanted to know what the max level you can get your profile up to. I'm a new player and I have no idea what it is.

You can level up your profile to 30. Once you are 30, it unlocks ranked play where it tracks your ELO (a numeric skill level).

As of Patch 7.22, League of Legends has uncapped leveling as per this Preseason Update FAQ

What’s the new level cap?

There’s no level cap! Level to infinity (but not beyond it—it's dangerous to level beyond infinity).

There is no max level in League of Legends. With the most recent update it has become possible to reach any level in the game.

The maximum summoner level outside of a match is level 30.

The highest level for a champion during a match is level 18.

The max level is 30 and then it becomes ranked.
