Capacity sheets that match the floor plan you actually used
Why published room capacities and last-minute seating changes confuse fill-rate charts—and how to align them.
Fill rate is only meaningful when the denominator matches the seats on the floor. Many venues publish a theatre capacity that assumes a dense chair layout, while your program team later clears rows for cameras or accessibility aisles.
Before the first session, photograph each room and count chairs in a single pass. Record that number beside the official capacity. If you reduced seats by fifteen percent for a panel stage, your attendance charts should use the reduced figure.
Share both numbers with anyone preparing reports. Sponsors often ask why a “500-seat” hall looked half empty when only 380 chairs were set. A clear capacity note prevents that awkward exchange.
For recurring venues in Bangkok, keep a small library of floor photos tagged by layout name. Reusing last year’s sheet when the stage footprint changed is a common source of skewed utilization charts.
