The essentials
  • Plated dinner: 1 server for every 10 guests, or 1 for every 8 with three courses and wine poured at the table.
  • Buffet: 1 server for every 20 to 25 guests, to clear, restock and handle drinks.
  • Full bar: 1 bartender for every 50 guests. Beer, wine and soft drinks only: 1 for every 75.
  • The first hour at the bar is the busiest. An extra bartender or a second bar during cocktail hour covers that peak.
  • Get it in writing: how many people and how many hours the quote includes, with setup and breakdown.

A hundred seated guests need about ten servers. With six, the main course reaches the last tables lukewarm and empty glasses sit on the tablecloth until dessert.

The number changes with the service style and is almost never written in the quote. Many just say "staff included" without saying how many people or how many hours. These are the ratios caterers use to plan.

The count by service style

  • Plated dinner served at the table: 1 server for every 10 guests. With three courses or wine poured at the table, 1 for every 8.
  • Family style, with large platters to share: 1 server for every 12.
  • Buffet: 1 server for every 20 to 25 guests. They don't plate the food, but they clear, restock the trays and handle drinks.
  • Cocktail hour with passed appetizers: 1 for every 25.
  • Full bar, with spirits and cocktails: 1 bartender for every 50 guests.
  • Beer, wine and soft drink bar: 1 bartender for every 75.

These are starting points, and they don't match from one guide to the next. For a buffet, some caterers ask for 1 server per 15 guests and others work with 1 per 40. What moves the number is the menu and the venue.

A server carries 2 or 3 plates per trip. With 10 guests to cover, their share of each course goes out in 4 or 5 trips. With 6 servers for 100 guests, each one gets 17. That's 6 to 9 trips.

With 10 servers for 100 guests, each course goes out in 4 or 5 trips per server.

What drives the count up

  • A kitchen far from the tables. If each trip takes 1 extra minute, 5 trips add 5 minutes per course. At a 3-course dinner, the last plate arrives 15 minutes late.
  • Several courses. Appetizer, soup, main and dessert are 4 rounds of serving and 4 of clearing.
  • Wine poured at the table instead of bottles in the middle. The server goes back to every seat several times an hour.
  • Older guests or small children at a buffet. Many don't get up and ask for a plate to be brought to them.

And what brings it down: large platters in the middle, a buffet with two lines instead of one, and a bar with 2 house cocktails premixed in pitchers instead of a menu of 10.

The bar, hour by hour

The first hour is the busiest. Almost everyone orders something on arrival and many order 2. With 150 guests and 2 bartenders, each one serves 75 people that hour. That's more than one drink a minute.

Many caterers add an extra bartender just for cocktail hour, or open a second bar and close it when dinner starts. A side table with water, soft drinks and poured wine takes the orders that don't need a bartender off the bar.

With a full bar and more than 100 guests, ask whether there's a barback. That's the person who brings ice, washes glasses and restocks bottles. Without one, the bartender leaves the bar every time the ice runs out.

The hours count too

Staff arrive before the guests and leave after them. For a 5-hour event, the usual is 1.5 hours of setup before and 1 hour of breakdown after. That's almost 8 hours per person.

Ask whether the quote covers those hours or only the event itself. If the event runs an hour long, overtime is billed per person. With 12 servers, that's 12 hours.

Four questions for the caterer

  1. How many servers and bartenders does the quote include, and for how many guests is it calculated?
  2. How many hours does it cover, with setup and breakdown?
  3. Who manages the staff during the event? With more than 100 guests, the ideal is a captain who doesn't wait tables.
  4. What happens if 20 more guests confirm a week before? Do they add staff or spread the same team across more tables?

If a quote gives 1 server per 20 guests for a plated dinner, ask whether they calculated it as a buffet.
