Before a floor plan is drawn, organizers need a rough answer to one question: how many booths can this hall actually hold? Venue brochures quote gross square footage, but a large share of that space goes to aisles, registration, the stage, food service and storage. Guessing high leads to overselling and last minute reshuffles; guessing low leaves money on the table when you negotiate the venue contract.

This calculator subtracts the space you reserve for non-booth uses, removes the share you plan to dedicate to aisles and circulation, then divides what is left by your standard booth size. It applies your sponsor hold percentage to show how many booths are genuinely open for sale and multiplies the full count by your average price for a gross revenue ceiling. It is a planning estimate, not a fire code or venue calculation; column placement, fire lanes and irregular room shapes will change the final number.

How to use this tool

  1. Enter the usable exhibit floor area from the venue spec sheet, then the square footage you plan to give to registration, stage, lounges and storage.
  2. Set the aisle percentage to match your layout standard and choose the booth size that dominates your floor plan.
  3. Add your sponsor hold percentage and average booth price to see how many booths are open for sale and the revenue ceiling of the floor.

What the math assumes

  • Reserved space is subtracted first, then the aisle percentage is applied to what remains.
  • Every booth uses the single standard size you select; mixed floor plans with islands and peninsulas will fit fewer booths.
  • The booth count is rounded down to whole booths; no partial booths are counted.
  • Sponsor holds are rounded to the nearest whole booth and are still counted in gross revenue at the average price you enter.
  • The estimate ignores columns, fire lanes, loading doors and irregular room shapes, which usually reduce the real count. The 35 percent aisle default is only a starting point; replace it with your own layout standard.

Frequently asked questions

Why does the calculator subtract reserved space before applying the aisle percentage?

Registration desks, stages and lounges are fixed areas that do not need aisles carved out of them in the same proportion as the booth blocks. Removing them first gives a cleaner estimate of the exhibit blocks you can actually sell.

Does this replace a venue floor plan or a fire marshal review?

No. It is a planning estimate to size your sales targets and venue negotiation. Column locations, egress paths and the fire marshal's aisle width requirements will change the final count.

How do I handle a mix of 10 x 10 and 20 x 20 booths?

Run the calculator once per booth size using the share of floor you intend for each, then add the counts together. Or run it with the 10 x 10 size and treat every four inline booths you plan to merge as one island.
