Everything about buffet and party quantities
Why use a buffet quantity calculator?
Estimating food and drink quantities for an event is tricky: too little and your guests leave hungry, too much and you waste money on leftovers. Professional catering standards provide the baseline for getting it right.
This tool factors in all the key variables — event type, duration, guest profile, summer heat — to produce a personalized shopping list with practical benchmarks: number of bottles, baguettes, and platters.
Whether you are hosting a casual drinks reception, a corporate buffet, or a large celebration, this calculator saves time and prevents unpleasant surprises on the day.
Who uses this tool?
- Home hosts planning a private event
- Calculate exact quantities for your cocktail party, birthday, farewell drinks, or dinner party without risking waste.
- Corporate event planners
- Plan office buffets, launch cocktails, and client receptions with quantities calibrated to your guest count.
- Caterers and restaurant professionals
- Quickly verify your per-person quantity estimates and adjust based on the type of service and event duration.
- Community groups and event committees
- Organize fairs, neighborhood meals, and community events knowing exactly how much to buy for 50, 100, or 200 guests.

Frequently Asked Questions
- How many champagne bottles do I need per person for a cocktail party?
- For a pre-dinner drinks reception (1.5h), allow one bottle of champagne per 6 guests (roughly 1.5 glasses each). For a longer cocktail dinner, plan on one bottle per 5 guests. A standard 75cl bottle fills 6 champagne flutes. Always round up — running out of champagne is a hosting faux pas.
- How much charcuterie per person for a buffet?
- For a full cold buffet, allow 250g (9oz) of charcuterie per adult guest. For a cocktail dinner, 175g is sufficient. For a short pre-dinner aperitif, 80g per person is a solid baseline. Offer at least three varieties — a cured ham, a salami-style meat, and a terrine or pâté — for a well-rounded platter.
- How many canapés and bites per person?
- For a pre-dinner drinks reception, plan 5 to 7 savoury pieces per person. For a cocktail-style dinner (replacing a full meal), allow 10 to 12 savoury bites and 3 to 4 sweet ones per person. For a 3-hour cocktail party, professional caterers typically plan 18 to 20 pieces total per guest.
- How much cheese per person for a party platter?
- Allow 40 to 50g of cheese per person for a pre-dinner aperitif, or 60 to 80g for a cocktail dinner or buffet. If cheese is the centrepiece of a sharing board, go up to 100 to 120g per person. Include 3 to 4 varieties — a soft rind, a firm aged cheese, and a goat or sheep milk option — to cater to all tastes.
- How do I calculate wine quantities for a buffet?
- The standard rule is one bottle of wine (75cl) per 3 to 4 guests over a 2 to 3-hour event. For longer events, plan one bottle per 3 people. For a typical buffet, split roughly 60% white and 40% red. For 20 guests over 3 hours, budget around 6 bottles of white and 4 of red as a starting point.
- Should I buy more food for a buffet than a sit-down dinner?
- Yes, slightly. At a buffet, guests serve themselves and tend to take a bit more of dishes they enjoy. Add 10 to 15% extra compared to a plated meal, and compensate by offering more variety — the wider the selection, the less any single dish is over-consumed.
- How do I adjust quantities if many guests don't drink alcohol?
- Use the 'Sober' drinking profile in the tool: alcoholic drinks are reduced by 35% and non-alcoholic options increased by 30%. As a practical rule, plan 3 non-alcoholic drinks per non-drinking guest (water, juice, sodas). Non-drinkers typically consume more soft drinks to compensate.
- How much bread do I need for a buffet?
- Allow 80 to 100g of bread per person — one standard French baguette (250g) covers 3 guests. If your buffet features lots of charcuterie or cheese, increase slightly. For events lasting over 2 hours, choose country-style loaves or sourdough over baguettes: they stay fresh much longer.
Planning quantities for your event
How many bottles of champagne do I need for 20 people?
For a 1.5-hour pre-dinner reception with 20 people, plan for approximately 4 bottles of champagne — one bottle per 5 to 6 guests, as each 75cl bottle fills 6 flutes. For a longer cocktail dinner, increase to one bottle per 4 guests.
How many pieces per person for a cocktail party?
For a cocktail-style dinner party replacing a full meal, allow 10 to 12 savoury bites and 3 to 4 sweet pieces per person — 14 to 16 pieces total over a 3-hour event.
How much charcuterie per person for a buffet?
Professional caterers recommend 250g (9oz) of charcuterie per adult for a full cold buffet, or 175g for a cocktail dinner reception.
How much food should I prepare per person for a party buffet?
As a general rule, plan for roughly 500 to 700g of food per adult guest at a buffet (excluding drinks), adjusted for the event type — more for a full meal buffet, less for a pre-dinner cocktail reception.
How many wine bottles for 30 people at a party?
For 30 people over a 3-hour evening event, plan 8 to 10 bottles of wine total — roughly 6 white and 4 red for a classic buffet, or one bottle per 3 to 4 guests.
