Understanding Burger Portions

Classic cookout staple. Plan for 1-2 burgers per person depending on appetite. When planning for a group, the key is knowing that the average adult consumes 1.5 servings of burger.

Factors That Affect Portion Size

  • Time of day: Lunch portions are typically 20% smaller than dinner portions.
  • Other foods: When serving multiple dishes, reduce burger by 25-30%.
  • Guest demographics: Teenagers eat more, seniors and young children eat less.
  • Event type: Casual events see more eating; formal events see less.
  • Duration: Longer events need more food as people graze over time.

The Formula

To calculate burger for any group:

Number of Guests ร— 1.5 = Total Servings

Pro Tips for Burgers

  • Buy 20% more patties than guests for seconds
  • Offer both beef and veggie options
  • Pre-form patties the day before
  • Set up a toppings station with lettuce, tomato, onion, pickles
  • Toast buns on the grill for extra flavor

Common Mistakes to Avoid

  • Don't assume everyone eats the same amountโ€”always add a 10-15% buffer
  • Don't forget about dietary restrictionsโ€”have alternatives ready
  • Don't order last minute for large groupsโ€”plan ahead for best selection
  • Don't underestimate hungry crowdsโ€”when in doubt, order more

Frequently Asked Questions About Burger

How many burgers does one person eat?

On average, one person eats 1.5 burgers of burger. This can vary based on appetite, whether it's a main dish or appetizer, and what other foods are being served.

How do I calculate burger for a group?

Multiply the number of guests by 1.5 (the average per person). For example, for 20 people: 20 ร— 1.5 = 30 burgers.

Should I order extra burger?

Yes, it's smart to order 10-15% extra to account for big appetites, unexpected guests, or leftovers. It's better to have a little too much than run out during your event.

Do kids eat less burger than adults?

How many burgers should I make per person?

What size burger patties should I use?
