Every venue mapped in St. Louis appears above. The ones with enough published detail to be worth reading have their own guide and are linked; the rest are named here, which is honest about what the record holds without giving each of them a page made of three facts.
Convention and exhibition space
3 venues in St. Louis are classified as exhibition or convention space. They are the only rooms here designed around a floor plan rather than a seating plan.
- America’s Center Convention Complex66,000 seats
- Fairgrounds Park Placesize not published
- Fairgrounds Marketsize not published
Capacities are the figure the venue or an encyclopaedia entry published. They are usually the seated maximum, and the same room in banquet or reception layout can differ by half. Confirm the layout you want before you plan around a number.
How people reach St. Louis
St. Louis Lambert International Airport (STL) is 19 km (12 mi) out — a normal airport transfer, worth an hour in the run of show on the first morning.
St. Louis keeps Chicago time (America/Chicago), which matters most for the remote speakers you are dialling in.
University City, Fairview Heights and Collinsville are close enough to draw from for a day rate, and to fall back on if St. Louis has nothing free on your dates.

Shows that return every year

Before you hold a date
The city is smaller than the market
279,695 people live in St. Louis itself, but about 2.8 million live in the wider St. Louis, MO-IL. Your local audience is far bigger than the city line suggests, and so is the commute your day-rate attendees will make.
Choice is not the constraint here
With 74 venues mapped, availability rarely fails. What fails is comparison: shortlist on capacity and distance from the airport first, and only then start touring.
Check the city calendar first
St. Louis carries recurring shows including Urbana, National Conference for Media Reform and 27th International Conference on Software Engineering. Hotel rates and venue availability move sharply around them, so pick your dates against that calendar rather than against your own.
What event67 costs for a St. Louis event
A St. Louis programme at 950 activated attendees — sized to America’s Center Convention Complex, the largest stated capacity in the St. Louis dataset — prices like this. Nothing is charged for the first 50, and nothing at all is charged past 1,000.
- activated attendees
- 950activated attendees
- billable, after the first 50 are free
- 900billable, after the first 50 are free
- for the whole event, at $5 each
- $4,500for the whole event, at $5 each

By event type
With a stated ceiling of 66,000 seats, St. Louis can carry a full trade show or a multi-track annual meeting without splitting the audience across buildings.
- trade shows and exhibitions
3 exhibition or convention halls mean a booth plan is possible in St. Louis without renting a marquee.
- multi-track conferences
A 66,000-seat room carries a plenary with breakouts running alongside it.
- association annual meetings
An association meeting needs one big room, several small ones and a hotel block, which is the combination St. Louis is set up for.
- festivals
An arena or stadium floor at 66,000 takes an audience no conference venue in St. Louis can.
- sports tournaments
The same rooms already run fixtures, so load-in and crowd flow are solved.
