Oftentimes, tornadoes are small and don’t make it far before dying out. However, large tornadoes are also present in many situations that track for very long distances. To determine the average track length of a tornado, both of these factors must be taken into account. The average track length for a typical tornado is about 1–2 miles, but they can vary from as little as a few feet to over 100 miles.
