The Fuijta Scale rates tornado from F0 to F5 based on the severity of the damage they cause. An F3 is a strong tornado that will cause severe and often irreparable damage to frame houses. A house that takes F3 damage will lose it roof and many, if not most of the walls will collapse. F3 tornadoes can obliterate trailers (though this is considered F2 damage), throw cars, and lift train cars. About 4% of tornadoes are rated F3.
Size is not the basis for rating tornadoes, nor is there any given size for a tornado of a particular rating. Ratings are instead based on the severity of the damage, rather than size. In an F3 tornado well-built houses will lose their roofs many and if not most of their walls while weaker structures may be completely destroyed and nearly all trees will be toppled. That said, F3 tornadoes tend to be on the large side, typically over 200 yards wide with some topping 1 mile. One EF3 tornado in 2007 was documented at over 2 miles wide.

No. While F3 tornadoes can be deadly they are not the deadliest. F5 tornadoes are the most destructive and generally the deadliest. The highest death toll from an F3 tornado in the U.S. since 1950 was 25, compared with nine F4 and F5 tornadoes with death tolls upwards of 50 of which three (all F5 or EF5) killed more than 100 apiece.
