Calculate The Number Of Guests

Before you order in food, you need to get a headcount of the number of people attending your event. Knowing how many attendees there will be is arguably the most important step.

This means you can estimate the portions needed in bulk, so you can prevent food wastage after the event. We recommend gathering this data around two or three days before an event, so you have sufficient time to plan properly.

Generally speaking, if you’re catering for a sit down meal, each guest will eat a single portion of food. But, for a buffet, things are slightly different. You will require a lot more food as people will serve themselves. And, let’s face it, most of us go overboard at buffets!

If you choose appetisers, main dishes, desserts, and drinks, you can then calculate the amount of each food needed to ensure you don’t run out.

While the amount of people going may alter, regardless of whether they RSVP or not, this remains a great approach when estimating how much food to buy.

Top Tip: Of course, you are maybe catering for someone else’s event. If so, request that they establish an RSVP deadline, so you can gather a more accurate head count.

Menu

The type of event you’re arranging determines the catering menus and serving amounts. When arranging a corporate event, for example, you are more likely to consider dietary requirements than when organising a get-together party with friends and family.

Of course, you should still be vigilant of people’s dietary needs, but for corporate events, you will probably be dealing with a lot more people.

The Event’s Time

Discuss the date and time of the function with the host, as this may affect the amount of food you need to prepare. For example, an after-dinner event is unlikely to require as much food as an all-afternoon affair.

Always anticipate serving more food for mealtime events. For these events, such as breakfast, lunch, and dinner, guests will always be expecting a full meal.

However, if your meal is not in peak-time, like mid-afternoon or in the evening, smaller, snack-sized portions should suffice.

Portions Per Person

You should calculate the exact portions of food for each person. A decent estimate for the amount of food to serve to one guest is approximately 1.5 pounds (600g). Divide this by the number of servings, taking into account the main course, as well as the smaller side dishes.

Order Additional Cheaper Foods

If you’re worried that the main food for the event will run low or even run out, we suggest ordering cheaper foods such as salad, potatoes, and bread. These are excellent for filling people up and are inexpensive, making them terrific choices for back-up servings.

Remember, you shouldn’t have to stress about running out of food. Simply stock up on a handful of your inexpensive side dishes or snacks, and you should be covered.

Follow Your Budget

You do not want to end up delivering less food than required or serving too much food. This is why you need to make sure you communicate financial details throughout the planning process.

Some hosts will wish to keep costs low, while others may have no such concerns. Discuss the projected menu and flag any potentially expensive items. This way, you should be able to stick to your budget more easily.

Appetisers During Meal Time

Knowing how many appetisers to serve is important when it comes to calculating food portions for catering.

For the main meal, you should plan for each guest to eat around 8 to 10 appetisers. For non-sit-down dinners, you should have enough d’oeuvres for each guest to enjoy for at least 8 hours. Then, simply multiply this by the number of guests attending and the hours the vent will last for.

This should give you a pretty accurate estimate for appetisers. If the sit down meal is later, you should prepare 3 or 4 appetisers. Each one will count as 1 bite per serving. For appetisers before a meal, each guest will typically eat 3 to 4 per hour.

Multiply this by how many guests there are and the hours the event will last and this will, again, give you the quantity of appetisers required.

Guidelines

While there is no definite method to calculate food portions perfectly for catering, you can follow some general guidelines. These are set out below:

  • Make sure you have more main dishes than appetisers/side dishes.
  • Always pay close attention to dietary requirements and requests.
  • Round up your estimates rather than down.
  • Multiply the number of people attending the event by three to calculate the appetisers needed.
  • Remember, people typically eat more at buffets, so order more in for these events.
  • Keep an allowance to cater for more guests than you anticipated.
