My 7 month old uses a large crate and my 1 year old uses an XL crate. I think the most important measurement for bassets is the length of the crate rather than the height.
The most important thing a crate does is teach your dog that they can hold it. They learn that they don't have to go as soon as they feel the need.
Never crate in anger. It'll set you back and your dog will fear the crate.
Use the crate when you can't immediately have eyes on your pup. You can leave the crate in a family room so the pup can still see and smell everybody and they don't feel forgotten in a back room. At night, if you want to you can move the crate into another room.
Make the crate a fun place for the pup to be. If you leave it in a family area during the day, leave the door open so your pup can explore it at their leisure. When you catch the pup in the crate, then praise her and give a treat. Or you can drop a treat in randomly throughout the day so when your pup explores it they find a surprise! This will make them regard the crate as a fun place that gives treats.
Train the pup to go into the crate also. My husband and I did this by throwing a treat to the back of the crate and when the pup went in to get they got praise and got to come back out. Eventually, we would close the door behind the pup. We'd leave the door closed for a little bit and then let them out giving them treats and praise. We'd gradually lengthen the amount of time we'd leave the door closed until the dogs were comfortable with any amount of time. Now, we don't even have to tell them to get into their kennels at night. I just have to walk to their bedroom and in they both go!
I think those are the points that seem the most important to me. I'm sure everyone else will have other things to suggest. Good luck!
