What is the standard height of a traffic cone?

The standard height of a traffic cone typically used for roadway work is 28 inches. This size is recognized for its effectiveness in being visible and providing adequate warning to drivers. A 28-inch cone strikes a balance between being tall enough to catch attention while remaining manageable for placement and storage.

Cones of other heights may exist; however, 28 inches has become a widely accepted standard due to its visibility and effectiveness in various traffic control situations. Smaller cones may not be noticed as easily, and larger cones can be more cumbersome to handle. This height ensures that the cone stands out sufficiently in typical driving conditions, allowing for effective safety and guidance on roadways.
