How many people will an 18 pound turkey feed?

However, this can vary based on:

* Appetites: If you have a group of big eaters, you might need a bit more turkey.

* Side dishes: If you're serving lots of other food, you might need less turkey.

* Leftovers: If you want plenty of leftovers, you might want to go with a slightly larger turkey.

It's always better to err on the side of having too much than not enough. So, if you're unsure, consider getting a turkey that's a bit larger than you think you'll need.
