A fluid ejecting apparatus includes a rotatable drum that holds a medium on a periphery thereof, a head that ejects a fluid onto the medium held by the drum, a fixing portion that fixes the fluid ejected from the head onto the medium, an outer-radius measuring portion that measures an outer radius of the drum, an adjusting portion that adjusts a distance between the drum and the head, and a controller that causes the adjusting portion to adjust a distance between the head and the medium in accordance with a variation in the outer radius of the drum measured by the outer-radius measuring portion.
