About Calculators

About Our Food Calculators

These food calculators were created to solve a simple problem: knowing how much food you actually need.

Whether you're planning a BBQ, a party, a wedding, or a small event, getting quantities right is harder than it looks. Order too little and you run out. Order too much and you waste money.

These tools are designed to give you realistic, practical estimates based on real-world experience.

Built from real catering experience

These calculators are developed by Cuisine Errante, a mobile catering business operating across North West France.

We prepare and deliver food for events every week, including BBQs, private gatherings, and large group orders. The portion sizes used in these tools are based on what people actually eat at real events, not theory.

Over time, you learn patterns. How much meat people eat at a BBQ. How much food disappears at a buffet. How portion sizes change depending on the type of event. These calculators are built from those patterns.

What these calculators are for

These tools are designed to help you:

  • Estimate food quantities quickly
  • Avoid under-ordering or over-ordering
  • Plan events with more confidence
  • Get a realistic starting point for shopping or catering

They are suitable for:

  • BBQs and outdoor events
  • Birthday parties
  • Weddings and celebrations
  • Buffets and casual catering
  • Family gatherings

Important note

Every event is different. Appetite, age groups, alcohol, time of day and menu variety all affect how much people eat.

These calculators provide practical estimates, not exact guarantees. It is always sensible to include a small buffer when planning food for a group.
