Frequently Asked Questions

Q

How much food per person for a catered event?

Plan 1–1.25 pounds of total food per adult for a seated dinner: 6 oz meat, 5 oz sides, 3 oz salad, and 3 oz dessert. Buffets need 10–15% more since guests serve themselves. Children eat about half the adult portion.

  • Seated dinner: ~1 lb total food per adult
  • Buffet: ~1.2 lbs per adult (guests take extra)
  • Cocktail party (heavy apps): ~0.75 lbs per person
  • BBQ: ~1.3 lbs per adult (larger meat portions)
  • Children: 50% of adult portions

Meat/Protein4 oz6 oz5 oz8 oz
Sides3 oz5 oz6 oz6 oz
Salad2 oz3 oz3 oz2 oz
Dessert2 oz3 oz3 oz2 oz
Q

How many drinks per person for an event?

Plan 2–3 drinks per person for a 2–4 hour event. For longer events, add 1 drink per hour. Cocktail parties and BBQs average 3 drinks per guest. Always have water available in addition to other beverages.

  • 1–2 hour event: 2 drinks per person
  • 2–4 hour event: 2–3 drinks per person
  • 4–6 hour event: 3–4 drinks per person
  • Include 1 non-alcoholic option per 2–3 guests
  • Ice: 1–1.5 lbs per person
Q

How much extra food should I order?

Add a 10–15% buffer above your per-person estimates. This covers seconds, varied appetites, and ensures you never run out. Better to have 10% leftover than to run short. Some caterers recommend 5% buffer for plated events.

  • Plated dinner: 5–10% buffer (portions are controlled)
  • Buffet: 10–15% buffer (self-service leads to more waste)
  • Cocktail party: 15–20% buffer (grazing behavior)
  • Outdoor BBQ: 10–15% buffer
  • Factor in time of day: brunch guests eat less than dinner guests
Q

How do I adjust portions for children at events?

Children under 10 typically eat 50% of adult portions. Teens eat full adult portions. For mixed-age events, count children as half a guest for food but a full guest for drinks and seating.

  • Under 5 years: 25–30% of adult portion
  • 5–10 years: 50% of adult portion
  • 10–15 years: 75% of adult portion
  • 15+: full adult portion
  • Kids prefer simpler foods — plan separate kid-friendly options
