And I have since learned that event planners and space designers actually have rules of thumb for event density. Billy Mac, an event planner, swears by the following parameters for the number of square feet required per guest for different vibes: Examples: Square Feet Per Guest Sophisticated Lively Hot Dinner party 20 sq. ft. 15 sq. ft. N/A Cocktail party 12 sq. ft. 10 sq. ft. 8 sq. ft. Into the night/dance party 8 sq. ft. 6 sq. ft. 5 sq. ft.
