How many booths fit in your exhibit hall?
Enter your hall dimensions and booth size to get a planning estimate, alongside the theoretical maximum you would reach if the floor had no aisles at all.
To estimate booth capacity, multiply hall width by length for gross floor area, subtract a circulation allowance for aisles and fire lanes, then divide by the area of one booth. A 300 by 200 ft hall is 60,000 sq ft; at a 40% circulation allowance that leaves 36,000 sq ft, or about 360 10x10 booths. The allowance is the variable that matters most, and it is set by your venue and fire marshal rather than by any national figure.

What Map D would cost for this event
Published per-event rates. Priced per event, not per seat, so adding organizers or exhibitors does not change the plan price.
- Starter$1,500 per event · 0.3% of projected revenue
- Growth$2,500 per event · 0.4% of projected revenue
- ScaleRecommended$2,750 per event · 0.5% of projected revenueSelling booth space means managing the exhibitors who buy it — their staff, assets, invoices and add-ons. Exhibitor self-service is what keeps that off email, and it starts at Scale.
What this assumes
Every figure the calculator starts with, and where it comes from. Where the honest answer is that a number depends on your venue, it says so rather than inventing one.
- 10 ft x 10 ft starting booth size
- The common inline booth unit at North American trade shows. It is an input, not a fixed value — change it for 10x20, 20x20 or any size your show sells.
- 40% circulation allowance
- Not a standard, and not sourced to one. Aisle widths, cross-aisles and fire lanes are set by your venue and the local fire marshal. 40% is a round number to start from, and the calculator shows the no-aisle maximum alongside it so you can see exactly what the allowance costs you.
- A rectangular hall
- Gross area is treated as one clear rectangle. Real halls are not rectangles, which is why the result is a planning estimate rather than a floor plan.
What it does not model
- Columns, service doors, loading docks and permanent fixtures.
- Registration, lounges, food service, stages and feature areas.
- Fire lanes and exit paths specific to your venue and local code.
- Island and peninsula blocks, which change how efficiently a grid packs.
- Ceiling height limits and rigging points, which can rule out large builds.

Frequently asked questions
What aisle allowance should I use?
There is no single correct figure, which is why this is an input rather than a constant. It depends on aisle widths, how many cross-aisles the plan needs, fire lanes required by your local authority, and how much floor goes to registration, lounges and features. Your venue or general service contractor will know what their halls actually run at, and that number beats any rule of thumb.
Why show a theoretical maximum I can never reach?
Because it shows you the cost of circulation. The maximum is what you would get if the hall were tiled edge to edge with booths and nobody could walk anywhere. The gap between it and the planning estimate is the floor you are giving up to aisles, and seeing both makes that trade visible instead of hidden inside one number.
How accurate is this?
It is a starting point for sizing a hall or sanity-checking a target, not a substitute for a drawn plan. Once you are placing real booths against real columns and exits, you need an actual floor plan. That is the point at which an interactive plan earns its keep.
Which Map D plan do I need to draw a floor plan?
The interactive floor plan is on every Map D plan, including Starter at $1,500 per event. Online booth sales starts at Growth. Pricing is per event rather than per seat, so adding organizers or exhibitors does not change what you pay, and there is no published cap on booths, exhibitors or attendees.
