This site gives a way to estimate table seating capacity/sq ft. for various configurations _http://www.louiswohl.com/SeatCapacity.html_ (http://www.louiswohl.com/SeatCapacity.html) and another interactive page from a tent rental company _http://www.kentuckytentrental.com/index.php3?pageid=29_ (http://www.kentuckytentrental.com/index.php3?pageid=29) -- found by a web search using the terms estimating seating capacity for other capacity measures- I believe the local fire dept would have input on that calculation.
