A bar is the busiest spot in the room. A line at the bar during cocktail hour is normal, but a line that blocks a door or runs through the dining area is a design failure. For a 100-guest wedding or party in Chicago, the layout is a small set of decisions: how many stations, how big, where, and what goes behind them.

The layout

Two bars spread the line; the dashed zones keep it from blocking tables and doors.

How many bars and bartenders

A rule of thumb is one bartender per 40 to 50 guests for a full bar and one per 75 for beer and wine only. At 100 guests that means two bartenders for a full bar. If your cocktail hour is short, one 8-foot bar with two bartenders works. If it is long or your guests drink heavily, add a second station.

Setup	Bars	Bartenders	Best for
Beer and wine only	1 (6 ft)	1 to 2	Casual, daytime
Full bar, short cocktail hour	1 (8 ft)	2	Plated dinner
Full bar, long cocktail hour	2 (8 ft + 6 ft)	3 to 4	Cocktail-heavy party
Signature drinks only	1 (6 ft)	2	Small drink menu

For more on staffing, see how many bartenders you need.

How much will they drink?

A common rule of thumb is about 2 drinks per guest in the first hour and 1 drink per guest per hour after that. For a 4-hour event with 100 guests, that is roughly 500 drinks. Your caterer or bar service will refine this by the crowd.

Bartenders, full bar, 100 guests: 2; Bartenders, full bar, 100 guests
Drinks per guest, first then each hour: 2 then 1; Drinks per guest, first then each hour
Drinks, 4-hour event: 500; Drinks, 4-hour event
Bar glasses: 250 to 300; Bar glasses
Ice per guest: 1 to 2 lb; Ice per guest
Queue space at each bar: 4 ft; Queue space at each bar

Ice is handled in how much ice for a party; the guideline from ice suppliers is 1 to 2 pounds per person.

What goes behind the bar

Bar front (6 or 8 foot), with linen or a plain front.
Back bar for bottles, mixers and garnishes, 6 to 8 feet long.
Ice bins or coolers, at least two.
Glass racks for storage, plus a trash can and recycling.
Cocktail napkins and bar tools. See the bar tools checklist.
A prep table at the end for cutting garnishes.
A tip jar and a drink menu sign at the front.

Placement tips for a Chicago room

Put the bar away from the dance floor and the entry so the line doesn't clog either. In many hotel ballrooms and banquet halls the venue will have outlets, ice access and a service door; ask where those are before you decide. For outdoor or tent events, bars need a flat, level surface and shade; a bar in direct sun melts ice quickly. For deeper layout thinking, see bar placement in the floor plan.

1Step 1Count your guestsand decide on full bar or beer and wine.
2Step 2Choose 1 or 2 stationsand size the bar fronts.
3Step 3Place barsaway from the entry and dance floor, with a 4-foot queue.
4Step 4Add back bar,ice and a prep table.
5Step 5Confirm staffingand who supplies glassware.

Dry hire or full service?

You can rent the bar equipment yourself or hire a company to provide bars, bartenders and stock. Each has different rules in Illinois; read dry hire vs full service and Illinois alcohol rules for private events before you decide.

Match the bar to the room

A dark wood bar fits a barn or a rustic tent; a white bar looks clean in a modern loft. Add chairs or stools only if you want guests lingering. For comfortable seating near the bar, a cross-back chair or a bar-height option sits well with a natural wood bar.

Frequently asked questions

How many bartenders do I need for 100 guests?

Two for a full bar, one to two for beer and wine only. Add a third if the cocktail hour is short and guests all arrive at once.

How big should the bar be for 100 guests?

An 8-foot bar handles one station with two bartenders. If you want two stations, an 8-foot main bar and a 6-foot second bar work well.

How many drinks should I plan for 100 guests?

Plan roughly 2 drinks per guest in the first hour and 1 per hour after that. For a 4-hour event, that is around 500 drinks. Your bar service can adjust for your crowd.

How many glasses do I need at the bar?

Plan 250 to 300 bar glasses for 100 guests, depending on whether guests reuse them. Our glasses per guest article gives the full count.

Should I have one bar or two?

Two bars for 100 guests if the cocktail hour is short or you serve a full bar. One bar is fine for beer and wine only or a long, relaxed party.

Where should the bar go?

Away from the entry and dance floor, near a service door or power source, with 4 feet of clear space in front. Avoid blocking aisles.

Do I need a license to serve alcohol?

Rules depend on the venue and city. See our Illinois alcohol rules article, and always ask your venue first.
