Researchers from Cambridge, Mass.-based MIT used high-speed imaging to record sneezes and slowed the video down to see how far sneeze droplets traveled. While the largest droplets from the sneeze settled about 3 to 6 feet away from the sneezer, smaller and evaporating droplets remain suspended longer and can wind up 26 feet away.

“The smaller and evaporating droplets are trapped in the turbulent puff cloud, remain suspended, and, over the course of second to a few minutes, can travel the dimensions of a room and land up to [19 to 26 feet] away,” the study reads.
