Theres a lot of factors that determine how fast they will grow.
But the more space you give them the faster they'll grow into it. If you keep them confined, the slower they'll grow. If you feed them right, they'll grow a little faster, etc.
My baby common outgrew my 10 gallon within a month. (this was before I really did any research on goldfish) I moved him into a pond after that.
