Checkerboard Seating ®is a seating distancing system that greatly reduces the likelihood of transmission of communicable diseases by distancing people in a seating arrangement. The average pitch (pitch means the horizontal distance between patrons) is 3 feet.
Droplet transmission is greatest in the area between 0 and 3 feet. Greater than 3 feet the amount and size of the droplets decreases exponentially. In theater seating, patrons are facing the back of each other causing there to be a reduction in infectious spread versus face to face interaction such as typically found in bars or nightclub event settings. Nothing in these statements should be suggested to mean that this is a perfect system, but the likelihood of transmission appears to be much lower in this environment than most other environments.
