Traffic Cone Sizes Explained<\/h1>\r\nChoosing the right traffic cone size matters for visibility, stability, and work-zone safety.<\/strong> A 12-inch cone may be perfect for a parking lot, while a 28-inch or 36-inch cone is a better fit for road work, lane guidance, and higher-visibility applications. This guide explains the most common traffic cone sizes, where each one is typically used, and what to consider before ordering cones for your crew, facility, school, warehouse, or jobsite.\r\n\r\nShop Traffic Cones at Traffic Safety Store<\/a>\r\n

12-Inch Traffic Cones: Small, Lightweight, and Easy to Store<\/h2>\r\n12-inch traffic cones<\/a> are the smallest common cone size. They are lightweight, portable, and easy to stack, making them useful for indoor applications and areas where vehicles are moving slowly or not at all.\r\n\r\nThese cones are often used for athletic drills, classroom activities, warehouse walkways, temporary indoor marking, and light-duty crowd guidance. They are not typically the right choice for roadway work because they do not offer the same visibility or target value as larger cones.\r\n

18-Inch Traffic Cones: Great for Parking Lots and Low-Speed Areas<\/h2>\r\n18-inch traffic cones<\/a> are a popular choice for parking lots, driveways, schools, churches, events, and private facilities. They are easier to move than larger cones but still provide a clear visual warning in low-speed areas.\r\n\r\nAccording to the MUTCD, cones used on daytime, low-speed roadways must be at least 18 inches high. For nighttime use, freeways, high-speed highways, or situations where more conspicuous guidance is needed, larger cones are required.\r\n

28-Inch Traffic Cones: The Standard Work-Zone Cone<\/h2>\r\n28-inch traffic cones<\/a> are one of the most common sizes for construction, road work, utility work, and temporary traffic control. They offer better visibility than 18-inch cones and are commonly available with heavier bases and reflective collars.\r\n\r\nThe MUTCD states that when cones are used on freeways and other high-speed highways, at night on all highways, or when more conspicuous guidance is needed, cones must be at least 28 inches in height.\r\n

Reflective Collars for 28-Inch Cones<\/h3>\r\nFor nighttime use, cones must be retroreflectorized or equipped with lighting devices. For cones that are 28 to 36 inches high, MUTCD retroreflective collar guidance calls for:\r\n
