One of the most frequently asked questions we receive from planners is “How much dance floor will I need?” Here’s an easy formula to help you decide: Simply multiply the maximum number of guests (not dancers) by 1.3, and that will give you the approximate square footage you will need.
The above formula works on the assumption that in most situations half of your guests will be wallflowers. If you think you’ll have more dancers than that, you can use a (slightly) more accurate formula which simply states that each dancer will need between 2.5 and 5 square feet of space. So, for 50 expected dancers you’ll need between 125 and 250 square feet. Easy, right?
Of course, some dancers will need more space and some dancers will need less space. It’s up to you to decide which type you’ll have more of. Remember though: when in doubt, it’s always in your benefit to err on the large size.
