Planning Food for Your Event
Catering is typically the biggest expense at any party, so getting portions right saves money and avoids waste. UK catering standards suggest around 400-500g of total food per adult guest for a full meal, or 8-12 pieces per person for finger food and canapes.
For a BBQ, plan around 250-300g of meat per adult plus sides. Pizza parties are simpler — roughly 3 slices per adult and 2 per child. Buffets work best with 5-7 different dishes and slightly more food overall since guests like variety.
Our food calculators account for the mix of adults and children, event duration, and whether you are serving a sit-down meal, buffet, or finger food. All portions use metric measurements and UK serving standards.
