Real event diagrams, made with EventDiagram
58 complete floor plans, to scale — weddings and galas, concerts and trade shows, a commencement for 984. Every picture on this page is the software’s own export, not a mockup.
Every one of these is the software
Each plan was drawn in EventDiagram, and each picture is its own scene data put through the app’s exporter — the same sheet a customer sends their client. No mockups, no stock photography, and not one number on these pages was typed: the seats, the objects, the areas and the aisles are all read back off the drawing.
6 are drawn in real event spaces reconstructed from the floor plans their venues publish. The rest are drawn in event spaces surveyed the same way — traced perimeters, 147 built features and 139 typed doors across 28 rooms. Not one of them is a bounding box.
How much floor a seat actually takes
The usable floor of each room divided by the seats placed in it, after the stage, the dance floor and the aisles are in. Not a rule of thumb — the median of drawings. Indoor seated plans only: standing formats are left out, because dividing a festival floor by its nine lounge chairs is a true sum and a useless one.
| Setup | Plans | Median ft² a seat | Range | Largest example |
|---|---|---|---|---|
| U-shape, hollow square & boardroom | 3 | 52.0 | 47.5–57.5 | Council Meeting — Guild Room (24 seated, 6 observing) |
| Pews & fixed seating | 1 | 20.3 | 20.3–20.3 | Sunday Worship — Fellowship Hall (315 in pews) |
| Classroom & crescent rounds | 5 | 44.6 | 35.0–122.9 | Certification Training — Carrick Junior Ballroom (144 classroom) |
| Long tables & family style | 8 | 61.6 | 36.2–93.8 | Reception — Grand Ballroom (210 at dinner) |
| Theater & rows of chairs | 9 | 21.4 | 13.2–65.0 | General Session — Lone Star Ballroom (1,743 theater) |
| Rounds & banquet | 12 | 48.3 | 20.6–140.9 | Gala Dinner — Lone Star Ballroom (1,120 at dinner) |
Theater rows pack tightest because a chair is all they place. Rounds carry a table, its chairs and the service lane between them — and in a wedding, a dance floor and a band as well — so the same head count takes two to three times the floor.
What each setup means
U-shape, hollow square & boardroom
Tables in a closed square or an open U with chairs on the outside only. For meetings where people present to each other rather than to a screen.
52.0 ft² a seat across 3 plans here · See one
Booths, stalls & stations
Exhibitor stands, market stalls or serving stations in runs, with aisles sized for a queue at one and a visitor walking past it.
212.5 ft² a seat across 9 plans here · See one
Pews & fixed seating
Fixed benches in rows. Denser than chairs and far quicker to reset, which is why a hall that seats a congregation keeps them.
20.3 ft² a seat across 1 plan here · See one
Classroom & crescent rounds
Tables facing the front with chairs on one side only — classroom when they are rectangles, crescent when they are rounds with the far seats removed. Both give people somewhere to write.
44.6 ft² a seat across 5 plans here · See one
Long tables & family style
Continuous runs of banquet or farm tables seating along both sides. Reads as one table rather than twenty, and seats more people per square foot than rounds do.
61.6 ft² a seat across 9 plans here · See one
Theater & rows of chairs
Chairs in rows facing one way, with no tables. The densest seating there is, and the only one where the aisle plan matters more than the seat plan.
33.3 ft² a seat across 13 plans here · See one
Cabaret, highboys & standing
Highboys and cocktail tables with no fixed seating, or a mix. What a reception actually becomes by the second hour.
525.0 ft² a seat across 6 plans here · See one
Rounds & banquet
Round tables, usually 60″ seating eight or 72″ seating ten, spread across the floor. The default for a dinner: everybody faces everybody, and the room takes a dance floor in the middle.

Questions these plans answer
How many round tables fit in a ballroom?
Fewer than the capacity chart says, once the event is in the room. JW Marriott Austin's Lone Star Ballroom is 204′ × 113′ and the hotel publishes 1,525 banquet. The plan in this gallery puts a 48′ stage and a 36′ × 26′ dance floor in it, keeps 12′ table centres, and seats 1,120 at 21 ft² a head. Both numbers are true; only one of them is a plan.
How much floor space does one seat need?
Across the 53 seated plans here it runs from 13.2 ft² a seat (General Session — Lone Star Ballroom, 1,743 theater) to 1228.8 ft² (Brand Activation — Loading Yard, 400 guests). The spread is the event, not the arithmetic: theater rows pack, a wedding with a dance floor and lounges does not.
How wide should an aisle be?
It depends what walks down it, and every plan here states its own. A ceremony aisle opens from 6′ 6″ at the front row to 10′ 6″ at the back; a mandap needs 12′ because a baraat arrives down it; a general session for 1,743 uses two 8′ longitudinal aisles and a 9′ cross aisle; a trade show runs 10′ between booth rows and a career fair 13′, because a queue at one table and a visitor walking past it is two people wide.
What size dance floor do I need?
Roughly a third of the room dances at once, so the floor is sized off the guest count rather than off the room. In this gallery 128 at dinner takes a 22′ × 18′ floor, 210 at dinner takes 32′ × 32′, and 1,120 at dinner takes 36′ × 26′ — each one drawn to scale so you can see the tables it costs.
Are these real venues?
Two of them are: the JW Marriott Austin's Lone Star Ballroom and ADERO Scottsdale's Four Peaks Ballroom, reconstructed from the floor plans those hotels publish — those pages say what the geometry was traced from and what it was checked against. The rest are event spaces surveyed the same way, with traced perimeters, built features carrying real heights and typed doors with swings. None of them is a bounding box, which is the thing that would make a plan on this page worthless.
Can I copy one of these layouts?
That is what they are for. Every plan here was drawn in EventDiagram and exported by it; you can draw your own event space to scale for free, and your clients and venue never pay to look at it.
