To add to what Dogmama said, if the crate is too big but will be the right size when your dog is full grown, you can place a sealed box in the back half of the crate while the pup is small to reduce the available space now. You'll want to get a box that doesn't have tears or flaps that would be attractive for chewing though.

My sister did this with her dog and replaced the box with smaller and smaller boxes as Dixie grew, which slowly alllowed more space for the dog but not more space than she needed. It worked well and saved my sister the cost of buying multiple crates.
