Party food calculator (snacks, sweets, cake)
Find out how many snacks and sweets, and how much cake, to prepare by guest count.
Estimate: ~10 savory and 5 sweet per adult, 100 g of cake per person.
How the calculation works
The calculator sizes savory snacks, sweets and cake by the number of guests, using party averages:
- Savory snacks: ~10 per adult (~6 per child)
- Sweets: ~5 per adult (~4 per child)
- Cake: ~100 g per person
Step-by-step example
A party with 20 adults and 10 children:
- Savory: 20×10 + 10×6 = 260
- Sweets: 140
- Cake: 30 × 100 g = 3 kg
Examples
- 15 adults: ~150 savory, ~75 sweets, 1.5 kg of cake.
- Near dinner, add ~30% to savory snacks.
Frequently asked questions
What if it is near dinner?
Increase savory snacks by ~30%, as people eat more.
How many types of snacks and sweets?
For variety without waste, 4–6 savory types and 3–4 sweet types usually work.
Should I order extra?
A ~10% buffer avoids trouble if last-minute guests show up.
How many savoury snacks per person?
It depends on the event: 8–10 per adult at a children's party, 6–8 with dinner served, 12–15 at a cocktail party and 15–20 at a wedding reception.
How much cake should I order?
About 100 g per guest — 3 kg for 30 people. Reduce slightly with a large dessert table.
More variety or more quantity?
Four to six well-stocked options beat twelve scarce ones. With too much variety people sample everything and total consumption rises.
