In short
- For a seated dinner, industry guides usually suggest one waiter for every 15-20 guests.
- For a buffet, industry guides recommend at least two people per station.
- For passed finger food, industry guides suggest one server for every 25-30 guests; for the bar, one bartender for every 50-75.
- These are references: the menu, venue and timing may call for more staff.
Staff are the item that most changes the quality of service and the one least visible in a quote. Too few waiters means cold dishes, empty buffets and queues at the bar. Too many cost money without adding service. Here you will find the reference ratios, with their source, and the questions to judge whether the number proposed is right.
A note on the numbers
In Italy there is no official rule on the number of waiters per guest. Each caterer has its own standards. The figures below are the estimates most often cited by industry guides. Use them to judge whether an offer is in the normal range, not as an obligation.
Reference ratios by format
| Format | Indicative ratio |
|---|---|
| Seated dinner | 1 waiter for every 15-20 guests |
| Finger food passed by waiters | 1 server for every 25-30 guests |
| Buffet with stations | at least 2 people per station |
| Bar and open bar | 1 bartender for every 50-75 guests |
Doing the maths for 100 guests: industry estimates give 5-7 waiters for a seated dinner and 2 bartenders for the bar. For a buffet with three stations, the two-per-station rule leads to at least six people behind the tables, plus those clearing among the guests.
Seated dinner
This is the format that needs the most staff. Each course must be brought out, cleared and followed by the next, table by table, at the same time. If there are too few waiters, the first table eats hot and the last one lukewarm.
Many wedding caterers think in terms of tables rather than guests: one waiter looks after a certain number of round tables. Ask how many tables each one covers and whether there is a maître, the floor manager who coordinates timing with the kitchen.
The number rises when:
- there are many courses or the service is silver service (the waiter serves from a platter onto each guest's plate);
- the kitchen is far from the dining room, as at some farmhouses in the Roman countryside with the field kitchen in another wing;
- the tables are on several levels or in several rooms.
Buffet
At a buffet guests serve themselves, but the buffet doesn't run itself. According to industry guides each station should have at least two people: one fixed behind the table, tidying and keeping an eye on things, and one going back and forth to the kitchen to restock.
On top of these come the people moving among the guests collecting plates and glasses. At a villa with a garden, where guests move around a lot, it is continuous work.
The same guides suggest about three metres of table for every twenty guests. More metres of buffet means more stations, and therefore more staff. To estimate space and quantities, read the guide to food quantities per person.
Aperitivo and passed finger food
The aperitivo at Roman weddings often combines fixed stations (cheese, cured meats, fried dishes, a pasta station) and waiters passing with trays. Industry guides suggest one server for every 25-30 guests for passed food. Stations follow the buffet rule.
If the aperitivo is outdoors in summer, also count whoever serves cold water. An hour and a half of aperitivo under the June sun calls for drinks non-stop.
Bar and open bar
Industry guides suggest one bartender for every 50-75 guests. The lower end of the range applies when everyone reaches the bar at once, for example straight after the cake cutting, or when the cocktails are elaborate. A bar serving only wine and sparkling wine moves faster than one making cocktails.
An example with a wedding
Take a reception for 120 guests at a farmhouse in the Castelli Romani: aperitivo in the garden with three stations, seated dinner, open bar after the cake cutting. With the ratios above, the aperitivo needs at least six people at the stations plus a few waiters with trays, the dinner 6-8 waiters, the bar about two bartenders. Many of these roles swap during the evening: whoever passes trays at the aperitivo then serves at the table. That is why the caterer gives the right number, but you already know which questions to ask.
Other roles to consider
- Cooks on site: with cucina espressa (dishes cooked on site) you need more people in the kitchen.
- Washing up: if tableware is washed on site, someone has to do it.
- Cloakroom and welcome: in winter or at corporate events.
- Event manager: the caterer's contact person for the whole evening. Ask who it is and how to reach them.
What changes the number in Rome
The venue. A villa on the Appia Antica with an equipped kitchen and a single room is easier to serve than a terrace in the centre with the kitchen on the floor below. A historic palazzo with stairs and long corridors needs more staff for moving around.
The hours. If the event runs late, waiters stay beyond the planned time. Every extra hour costs money: ask for the price of an extra hour, as explained in the guide to catering extra costs.
The guests. Children, elderly guests, people with allergies: they need more attention at the table. A reception with many children needs someone to look after their menu.
Questions to ask the caterer
- How many waiters do you plan for our guests and our format?
- How many tables does each waiter look after?
- How many people for each buffet station?
- How many bartenders, and until what time does the bar stay open?
- Is there a maître or floor manager?
- How many cooks work on site?
- From what time to what time is service planned?
- How much does each extra waiter and each extra hour cost?
- How are the waiters dressed? (It matters for a wedding or a gala dinner.)
- Who is the contact person during the event?
To finish
The number of waiters is judged by looking at format, venue and guests together. If one quote costs less than the others, staff are the first thing to check. The method for comparing offers is in the guide on how to read a catering quote.
For a wedding reception you can compare the wedding caterers; for a work event, the corporate caterers. When you have the details, you can request a quote and ask for the number of staff to be written down.
