Training Your Puppy

I bought a collapsible crate from petco for our new jack russle puppy. I bought it big enough so it will fit him comfortably as an adult dog as well. Was that a mistake? I ask because I was told in order to potty train a puppy using the crate training method the crate needs to be just big enough for them to lay down in. Is that true?

Any potty training tips because I don’t really want to buy a smaller crate at this point.
Thanks you guys! It’s our first dog and it was seriously ticking me off he kept going potty in his crate I’ll block off half of it… The answer was so simple I feel like a retard.
OMG (laughing at myself) The extra wire thingy! (slaps my forehead) it was the DIVIDER! hahaha
