Generally, in order to be generous, you should average about 1 packet of charcuterie hams for 3-4 people, and the same for one packet of cheese. As well, you should count 1/3 baguette per person or loaf of bread. So if you have 10 people at your party, you should have at least 4 types of hams, 4 types of cheeses and 3 baguettes. However, this assumes that you will be serving a few other appetizers and finger foods at your party. If you are not having other appetizers, I would recommend that you increase that proportion to 1 packet of charcuterie hams for 2-3 people, and the same for one packet of cheese. As well, you should count 1/2 baguette per person or loaf of bread. If in doubt, round up on portion sizes and keep the extra in the fridge so that you can bring it out if needed.
