The crock itself is not straight up and down. It is smaller at the bottom. It is 5 3/4" wide at the top and 4" at the bottom. It is 3 7/8" high. These are all interior measurements. Remember that you do not want to fill it completely to the top. You need to leave a little room or you will have a mess to clean up. It actually holds a lot more than it sounds. It is great for 1-2 people. I've used my for soup, stew, chicken and rice, roast with potatoes, carrots and mushrooms, meatballs, and more. I love it!
