What is the width of centerline markings on basic runways?

The width of centerline markings on basic runways is chosen to balance visibility with pavement space, so pilots can reliably see the axis of the runway during landing, takeoff, and taxiing. On basic runways, these centerline marks are typically within a range of 12 to 18 inches wide. This width is wide enough to be conspicuous from a distance and in varying weather, yet not so wide that it conflicts with other markings or takes up excessive surface area. A 6-inch width would be too narrow to be reliably seen, while 24 or 36 inches would be overly bold and could interfere with other markings or runway safety cues.
