4 to 6 quarts is the best size for most home cooks. A 4-quart soup pot can comfortably serve four people, while a 6-quart one can serve 4-6 people. If you plan to make larger batches of soup or cook for more people, consider a larger soup pot, such as an 8-quart or 10-quart size. It’s also worth considering the size of your stovetop and oven when choosing a soup pot. Ensure the pot will fit comfortably on your burners and in your oven, and it’s not too heavy to lift or move when it’s full.
