Quick answer

Plan per adult guest: 4–6 appetiser bites per hour for an appetiser-only party (or 2–3 before a meal), about 6–8 oz of main protein, 4–6 oz of sides, 1–2 dessert servings and 1–2 drinks per hour. Kids eat about half. Increase amounts for dinner-time parties and longer events, and add a 10% buffer.

Quick takeaways

  • Time of day changes everything — mealtime parties need meals.
  • Kids eat about half an adult portion.
  • Add a 10% buffer for surprise guests.
  • Drinks run out before food does — plan generously.

Adjust for time of day

Putting the time on the invitation (“light bites and cake”) sets expectations.

Kids’ portions

Children under 10 typically eat about half an adult portion, and they gravitate to simple foods: pizza, nuggets, fruit, crackers. Plan one slice of pizza per young child (two for older kids), plenty of fruit and a cupcake or slice of cake each. Always offer a water station.

Common food-planning mistakes

Leftovers plan

Have takeaway containers ready and send guests home with leftovers — it’s generous and saves your fridge. Freeze what you can within a couple of hours of serving, and donate untouched trays where local rules allow.

Serving setup

Put the buffet somewhere with flow — away from the entrance and the photo wall — and set drinks at a separate station to avoid queues. A balloon arch behind the dessert table frames the cake moment without crowding the buffet. Label dishes with allergens. For décor and budget planning, see party budget breakdown by guest count.

Stylist tipSet out food in waves — half at the start, refill at the midpoint — so it always looks fresh and abundant.
