3 large pizzas will be plenty! If you only have a fairly small amount of people coming and plenty of appetizers then that will be just the right amount :) and if they're are 1 or 2 piece left over I'm sure someone will beg to take them home, or if not it makes a great snack for the next day :)

Have a great party!

If he likes to eat (and his friends too), plan like 1 pizza for each men and 1 for 3 girls. If nobody is gonna be hungry plan 4 pizzas. Better to have more (you can eat those during the next days) than to have not enough.

I think 3 pizzas are a good amount.

Hello, I am planning a surprise birthday party for my boyfriend who is my bestfriend we have been through so much tougher, I plan on making a few appetizers ( warm bacon cheese spread with chips, mini meatball sandwich's) .. I am making a smartie and kit-kat birthday cake , there will be 3 boys with hearty appetizers and three girls, we are all around 16 years old!
