How many loaves of bread to feed 20 people?

This is tricky without more information! Here's why and how to figure it out:

* Bread Size: A "loaf" can be tiny or huge! Is it a small baguette, a large sourdough, or a giant Pullman loaf?

* Appetite: Are your guests big eaters or light nibblers?

* Other Food: Is bread the main dish, or just a side for a larger meal?

Here's a general guideline:

* Small Meal: If bread is the main focus, figure 1-2 slices per person for a smaller meal (think soup and bread). That's 20-40 slices. Most loaves have 10-16 slices, so maybe 2-4 loaves.

* Side Dish: If it's a side for a full meal, 1 slice per person is more likely. That's 20 slices, meaning you'd likely need 1-2 loaves.

To be safe:

* Overestimate: It's always better to have too much bread than too little! Round up to 3-4 loaves.

* Consider Variety: Offer different types of bread to appeal to different tastes.

Ultimately, the best way to know is to consider your specific needs and preferences!
