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.

| Dessert | 1–2 servings | Cake + something small |
| Drinks | 1–2 per hour | Plus water |

Adjust for time of day
Putting the time on the invitation (“light bites and cake”) sets expectations.
- Brunch (10–1) — full brunch: eggs, pastries, fruit.
- Afternoon (2–4) — snacks and cake; no full meal needed.
- Dinner time (5–8) — guests expect a meal.
- Evening (8+) — heavy appetisers and dessert.
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.
Quick calculator: 25 adults, dinner time
- Appetisers: 25 × 3 = 75 bites.
- Main protein: 25 × 7 oz ≈ 11 lbs.
- Sides: 25 × 5 oz ≈ 8 lbs across three dishes.
- Dessert: 25–35 servings.
- Drinks over 3 hours: 25 × 1.5 × 3 ≈ 110 drinks, plus water.
- Add 10% to everything.
Common food-planning mistakes
- Forgetting dietary needs — ask on the RSVP and label dishes.
- Too many options — three or four great dishes beat ten mediocre ones.
- Running out of ice — buy double what you think.
- No water station — put one out, especially in summer.
- Hot food going cold — use slow cookers or chafing dishes.
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.
