How Many Bartenders and Bars Do You Need for Your Guest Count?

Too few bartenders turns cocktail hour into a line, and too many costs money for people who stand around. The right number depends on what you serve and how fast guests arrive. Planners in Chicago use the same set of numbers; they are rules of thumb, so confirm with your bar company or caterer, who knows your crowd.

What drives the number

Drink type. A bartender can pour beer or wine faster than they can mix a cocktail. A shaken or built drink takes longer.

Arrival pattern. If 100 guests all arrive at once and head to the bar, the first 20 minutes is a rush. If guests trickle in over an hour, the load is lighter.

Length of cocktail hour. The longer it is, the more drinks per guest, and the more bartenders you need for the same line time.

Number of stations. Two bartenders at one bar get in each other's way. Two bars with one bartender each are often faster.

The chart

These are planning ranges, not rules from any licensing body. If your event is 6 hours with a fully open bar and heavy drinkers, use the top of the range.

One bar or two?

A single long bar lets two or three bartenders work side by side. It is simple to stock, simple to staff and easier to monitor. The downside is one long line. Two bars halve the line but need duplicate bottles, ice and glassware. Place the second bar where guests naturally gather, such as the cocktail area or near the dance floor. See bar setup for 100 guests for a layout and bar placement in your floor plan for how to position them.

Do you need a barback?

A barback restocks ice, glasses and bottles so the bartender never leaves the bar. For 100 guests or fewer, a barback is optional. For 150 or more, one barback per 2 or 3 bartenders prevents a stalled line. Some bar companies include them.

Servers and other staff

Bartenders are only part of the picture.

• Glass collection. One person to clear empty glasses from cocktail tables keeps the supply flowing.
• Wine service at tables. Servers pour at dinner; a bartender is not needed at the table.
• A bar captain on larger events, to manage inventory and cash-out.
• Security and ID checks. Some venues require this; ask.

Illinois and venue rules

Servers and bartenders at licensed venues in Illinois are required to complete state-approved alcohol training called BASSET. The requirements and who must hold a license can differ by city and by whether you are hiring a bar service or serving yourself. Read Illinois alcohol rules for private events and ask your venue or bar company for current requirements.

Cost without inventing numbers

Pricing depends on hours, bar company, venue and holidays. We don't publish bar staffing prices; request quotes from two or three bar services and ask what is included: setup time, breakdown, minimum hours and insurance. If you rent bars, glasses and tables through us, we price those with your seating quote.
