How much stuffing for 13 people?

For 13 people, a good rule of thumb is to prepare about 1 to 1.5 cups of stuffing per person. This means you would need approximately 13 to 20 cups of stuffing in total. If you're using a recipe, consider scaling it up accordingly or making a little extra to ensure everyone has enough. Adjust based on your guests' appetites and whether stuffing is a main dish or a side.
