Catering by rules of thumb
Professional caterers plan food with simple per-person rules. For a standing reception with appetizers, around six pieces per guest per hour keeps everyone happy. For a seated meal, plan one main portion per guest with roughly 180 g of protein and 150 g of sides each.
Appetizers vs. a full meal
If drinks and mingling are the focus, appetizers over a couple of hours are enough. If the event replaces a meal, switch to full-meal mode so protein and sides are sized to satisfy rather than just nibble.
Buy a margin, keep variety
Round up and offer a few options so there's something for everyone and you don't run short at the end. Vegetarian and lighter choices stretch the spread and cover dietary needs.
Frequently asked questions
How many appetizers per person?
About 6 pieces per guest per hour for a reception where appetizers are the main food. Fewer if a meal follows.
Does it account for dietary needs?
Not specifically — it gives totals. Set aside a share for vegetarian, gluten-free and lighter options based on your guests.
How much food do I need per person?
As a rough guide, plan about 500 g of food per adult for a main meal, more for a long event, plus a margin so you do not run short.
How do I cater for a large group?
Multiply per-person amounts by the headcount and round up. The calculator scales mains, sides and snacks to your guest number.
How much should I allow for kids?
Count children as about half an adult portion when planning, and add a little extra for popular items that go fast.
