How much food do I need per person for a buffet?

For a standard 2-hour buffet, plan for approximately 250-350g of food per person in total, spread across 8-10 different items. This works out to roughly 30-40g per item per person. For longer events, increase to around 400g per person with 12 items.

How many dishes should I offer at a buffet?

A good rule of thumb is 6-8 different dishes for a standard buffet. This should include a mix of proteins, carbohydrates, salads, and vegetable dishes. For larger events (50+ guests), consider 8-10 dishes to offer more variety without increasing the total food quantity per person.

Should I increase quantities for a buffet with mostly men?

Professional caterers sometimes add 10-15% for predominantly male groups, as average consumption tends to be slightly higher. However, the standard quantities already account for a mixed group and are generally sufficient for most events.

How do I account for dietary requirements at a buffet?

A good approach is to make 1-2 of your dishes naturally vegetarian or vegan, and label all dishes clearly. You do not need to increase the total food quantity for dietary requirements — the same total amount per person applies, just spread across suitable alternatives.

How much less food do I need for a light nibbles event?

For a light nibbles or drinks reception, plan for about 150-200g per person with 5-6 items. This is roughly 60% of a standard buffet quantity. These events typically last 1-2 hours and feature lighter, bite-sized items.
