Calculating the space you need for your next event can be tricky. How much room does the average person need to be comfortable? What if they’re seated? Standing? A mixture of both? And how do table sizes and dance floors factor in? 

Take a deep breath: We’re here to help. Consider this your cheat sheet for calculating space to source the right venue, no matter how big or small the event.

First things first: How many square feet does a person need? Between six to 10 feet is a safe bet. Generally, a loose crowd — one in which each person is about an arm’s length away from their nearest neighbor — requires 10 square feet per person. A more tightly-packed crowd fills closer to five square feet per person. You’ll want to consider your desired crowd density in addition to room capacity when deciding on a venue — remember that more space may also mean a less full-appearing room.

Now that you know how many square feet you’ll need to provide per person, you can start to estimate your space needs. 

Let’s give an example: A crowd of 100 will require a room of 600-1,000 square feet, minimum, without factoring in the specifics of your event: Different table sizes, rows of chairs, a buffet line, dance floor, etc. Your final space requirement will ultimately depend on what other elements are at play.

Take a look at our helpful chart to get a sense of how your space requirements will change depending on the type of event you’re planning: 

 

SPACE REQUIREMENTS, CROWD OF 100

EVENT TYPE/STYLESQUARE FT. REQUIRED
Cocktail party, guests standing600
Cocktail party, guests standing and seated800
Banquet/reception, round tables, plated1,200
Banquet/reception, rectangular tables, plated1,000
Banquet/reception, round tables, buffet1,400
Banquet/reception, rectangular tables, buffet900
Banquet/reception-style, with dance floor900 (minimum, 12x12 dance floor)
Theatre/auditorium style, spacious rows of chairs800
Theatre/auditorium style, maximum rows of chairs600
Conference style, standard3,000
Trade show, 8x10 booths8,600

By using the chart above, you can start to get a sense of what your event may need in terms of space requirements. A banquet-style event with round tables will require about 12 square feet per person, an auditorium-style presentation with comfortable rows of chairs will require about 8 square feet per person, and so on.

Here’s another quick guide to planning by expected crowd size:
