Calendar & availability Built
VenueDirector already holds each space with its capacity and shows every space on one calendar with conflict checks. This estimate is a planning tool only; the capacity you save is yours to set.
Get early accessHow is venue capacity calculated?
- Usable floor = floor area − stage − bar − dance floor − buffet. If the features take more than the floor, usable floor is 0.
- Guests = usable floor ÷ the space per guest for the layout, rounded down to a whole guest. Square metres are converted to square feet first (1 m² ≈ 10.76 sq ft), because the space per guest is in square feet.
- Fire-code cap: if you enter a fire-code maximum, every layout is capped at it, and the page says which results were capped.
Never exceed the occupancy limit on your permit.
What are the starting assumptions?
The calculator opens with an example room so you can see a result. Every number is a placeholder, not market data, and is editable:
- Room: 3,000 sq ft of floor, less a stage of 120, a bar of 100, a dance floor of 300 and a buffet of 80 sq ft.
- Space per guest, as planning rules of thumb: banquet 12 sq ft (1.1 m²); theater 8 sq ft (0.7 m²); cocktail 6 sq ft (0.6 m²); classroom 18 sq ft (1.7 m²). They are not legal requirements. Use your own layout plans if you have them.
- No fire-code maximum is entered until you add one.
Worked example
The example room has 2,400 sq ft of usable floor. A banquet at 12 sq ft (1.1 m²) per guest seats 2,400 ÷ 12 = 200 guests:
- Usable floor
- 2,400 sq ft
- Fire-code maximum
- None entered
| Layout | Space per guest | Guests |
|---|---|---|
| Banquet | 12 sq ft (1.1 m²) | 200 |
| Theater | 8 sq ft (0.7 m²) | 300 |
| Cocktail | 6 sq ft (0.6 m²) | 400 |
| Classroom | 18 sq ft (1.7 m²) | 133 |
Never exceed the occupancy limit on your permit.
With a fire-code maximum of 250 entered, the same room stops at that number in every layout that would fit more:
- Usable floor
- 2,400 sq ft
- Fire-code maximum
- 250
| Layout | Space per guest | Guests |
|---|---|---|
| Banquet | 12 sq ft (1.1 m²) | 200 |
| Theater | 8 sq ft (0.7 m²) | 250 (capped) |
| Cocktail | 6 sq ft (0.6 m²) | 250 (capped) |
| Classroom | 18 sq ft (1.7 m²) | 133 |
Capped at your fire-code maximum of 250. By floor area alone, theater would fit 300, cocktail would fit 400. Every result stops at the maximum you entered.
Never exceed the occupancy limit on your permit.
Frequently asked questions
- How is venue capacity calculated?
- Usable floor area is the floor area minus the stage, bar, dance floor and buffet. Guests = usable floor area ÷ the space per guest for the layout, rounded down. A seated banquet needs more room per guest than people standing at a cocktail reception.
- Are the space-per-guest figures official?
- No. They are planning rules of thumb, shown next to each result and editable. They are not market data and not a legal requirement. Replace them with the figures your venue, your caterer or your layout plan actually use.
- What if my permit or fire code gives a lower number?
- Enter it as the fire-code maximum. Every layout is then capped at that number and the page says so. Never exceed the occupancy limit on your permit, whatever any calculation says.
- Does this replace a floor plan or a fire marshal’s review?
- No. It is a quick estimate from floor area. Exits, aisle widths, fixed furniture, columns, staging and local rules can all lower what is safe and legal. Check the final layout with your venue manager and local authority.
- Which area should I enter, and in which units?
- Enter the floor you can actually use, in square feet or square metres, and the area taken by each feature you will put in it. Leave a feature at 0 if you are not using it. Space per guest is always in square feet, with the metric equivalent shown.
- Is anything I type sent to VenueDirector?
- Your numbers stay in your browser, which also remembers them for next time. We count anonymous events such as “a result was exported”, without your inputs or anything that identifies you. Your inputs and email are stored only if you ask us to email your results.
