How often will i need to buy my pleco a new hide out?

What kind of pleco is he I am in the process of getting a new hide for my pleco the one I have I don't know how he fits in there. Mine is a common pleco and they get big up to 2 feet long. Some other plecos are smaller and you get get by with just a small one. He should be fine in the bigger one but get the biggest one you can get.
