Frequently Asked Questions About Burger

How many burgers should I make per person?

Plan for 1.5 burgers per adult and 1 per child. Some guests will want seconds, so this accounts for varied appetites while minimizing waste.

What size burger patties should I use?

For parties, 4-6 oz patties are ideal—substantial enough to be satisfying but not so large they take forever to cook. Quarter pounders (4 oz) are the standard.

How much ground beef do I need per person?

Plan for 6-8 oz of ground beef per person (accounting for 1.5 burgers). For 20 people, buy about 8-10 lbs of ground beef.
