For a standard plated sit-down dinner with good but not Luxury catering services in Delhi, plan on 1 waiter per 15–20 guests. That means 5–7 waiters for 100 guests is typical in most restaurants and catered events.

But the real number depends on several factors. Here’s a clear breakdown professional event planners and caterers actually use:

General Guidelines for Service Types
Here is a breakdown of the standard staff-to-guest ratios for different service styles:

1. Plated (Sit-Down) Service
This is the most labor-intensive style, where food is brought directly to the seated guests.

Standard Ratio: 1 waiter for every 10-12 guests.

For 100 Guests: You would need approximately 8 to 10 waiters.

Note: If you are doing a very high-end or formal event (e.g., a multi-course meal requiring precise timing and synchronized service), you might increase the ratio to 1:8, requiring 12 to 13 waiters.

2. Buffet Service
In this style, guests serve themselves from a central area. Waiters are primarily responsible for clearing plates, refilling drinks, and pre-bussing.

Standard Ratio: 1 waiter for every 20-30 guests.

For 100 Guests: You would need approximately 3 to 5 waiters.

Note: You would also need attendants to manage the food lines, replenish chafing dishes, and keep the area tidy, typically 1 attendant per 50 guests.

3. Cocktail Reception (Passed Hors D'oeuvres)
For events focused on drinks and small, passed appetizers. Waiters circulate, offering food and sometimes drinks.

Standard Ratio (Food Service): 1 waiter for every 20-25 guests.

For 100 Guests: You would need approximately 4 to 5 servers dedicated to passing food.

Don't Forget the Support Staff
Keep in mind that the "waiters" are only one part of the total staff. For 100 guests, you will also need to factor in the following essential support roles:

Bartenders: The ratio is typically 1 bartender per 50-75 guests. For 100 guests, plan on 2 bartenders.

Bus Staff/Runners: These individuals assist the waiters with clearing dishes, bringing food from the kitchen, and maintaining tables. Plan for 1 busser for every 2-3 waiters.

Maitre d'/Captain: A dedicated supervisor who coordinates the entire front-of-house service. You need at least 1 Captain for an event of this size.

Key Factors That Increase Staffing Needs
To determine your final number, consider these elements that might require you to hire more staff than the basic ratios suggest:

Complexity of the Menu: Serving multiple courses, wine pairings, or tableside preparations (like carving or flambe) requires more staff.

Venue Layout: If the dining area is spread across multiple rooms or floors, or if the kitchen is far from the dining space, you will need more runners and waiters to cover the distance.

Beverage Service: If you are pouring wine for every course or offering extensive tableside drink service, the waiter count should increase.

Time Constraints: If the client requires the meal to be served and cleared very quickly (e.g., a 4-course meal in one hour), you will need extra hands for rapid service.
