A tornado that stays on the ground for about 2 miles is common. The average path length is about 5 miles. However, a mile wide tornado is rare. The vast majority of tornadoes are well under a mile wide.
Size is not a factor in determining the rating of a tornado. Ratings are based on the severity of the damage done, with F4 damage being near total destruction. F4 tornadoes have been recorded as small as 100 yards wide, but most are larger. It is not uncommon for an F4 tornado to be over a quarter or even half a mile wide. The widest tornado on record was an F4 that struck Hallam, Nebraska in 2004. It was 2.5 miles wide.

An F4 tornado can be a quarter of a mile wide, but that is by no means a requirement. Tornado ratings are based on the severity of the damage, not the size of the tornado. There is a tendency for violent tornadoes to be large, but they don't have to be. A path width of 1/4 mile would not be uncommon for an F4, but sizes have ranged from as small as 100 yards to as wide as 2.5 miles.
