How wide and how far apart are taxiway edge markings?

Taxiway edge markings define the boundary of the usable pavement, helping pilots stay on the taxiway and avoid wandering onto shoulders or grass. The standard for these markings uses a pattern that is six feet wide and repeats every six feet along the edge. This 6-by-6 setup keeps the boundary clearly visible from the cockpit and in various lighting conditions, while remaining consistent with other pavement marking practices. Dimensional choices other than six feet would reduce legibility or consistency, so the six-by-six dimension is preferred.
