Am I too small?

It’s already for your age below average I’d say. However, your biggest increase will certainly come. So it doesn’t have to say… it’s just patient…you’ll grow. And if nothing happens (which I think is highly unlikely) you cannot change it first and secondly, look at people like Lionel Messi. Messi is comparatively small but that has not affected him at all… on the contrary he is one of the best in the world.
