Sulcata growth rate?

[Bandit]

Hey everyone,

So my girlfriend has been wanting a tortoise for a while now, and she came across some baby Sulcatas recently. I'm all for it (who am I to turn down another reptile ). Our main concern is their growth rate since we are in a smallish condo right now and probably will be for the next couple of years. So how fast do these guys grow with proper care? Say within two years, how big is one likely to get?
