This is a list of tornadoes by their official and unofficial width. The average width of a tornado according to the National Weather Service is 50 yards (46 m).[1] The official widest tornado in history is the 2013 El Reno tornado, which a confirmed width of 2.6 miles (4.2 km), with the World Meteorological Organization believing the width could have been up to 1 mile (1.6 km) wider.[2]

List of tornadoes with a width of at least 2 miles (3.2 km)
Tornado F#/EF#/IF# Width Rated by
1999 Mulhall tornado F4 4.3 miles (6.9 km) NWS Norman, CSWR, Wurman, OU, Penn State
Officially, this tornado was just over 1 mile (1.6 km) wide. A Doppler on Wheels (DOW) mobile radar observed this tornado as it crossed Mulhall. The DOW documented the largest-ever-observed core flow circulation with a distance of 1,600 m (5,200 ft) between peak velocities on either side of the tornado, and a roughly 7 km (4.3 mi) width of peak wind gusts exceeding 43 m/s (96 mph), making the Mulhall tornado the largest tornado ever measured quantitatively.[3]
1946 Timber Lake tornado FU 4.0 miles (6.4 km) USWB
The United States Weather Bureau published in 1946 stating the width of the tornado was 4 miles (6.4 km), which would make this the widest tornado ever officially documented in history. However, this is outside the period of reliable documentation accepted by the modern National Weather Service, which is 1950–present.[4]
2013 El Reno tornado EF3 2.6 miles (4.2 km) NWS Norman, OU
This is officially the widest tornado to ever occur, with a width of 2.6 miles (4.2 km) at its peak. This is the width found by the National Weather Service based on preliminary data from University of Oklahoma RaXPol mobile radar that also sampled winds of 296 mph (476 km/h), which was used to upgrade the tornado to EF5.[5] However, it was revealed that these winds did not impact any structures, and as a result the tornado was downgraded to EF3 based on damage.[6]
1984 Maxton–Red Springs tornado F4 2.5 miles (4.0 km) NWS Wilmington, NC
The National Weather Service in Wilmington, North Carolina stated this tornado was 2.5 miles (4.0 km) at a point in time.[7]
2004 Hallam tornado F4 2.5 miles (4.0 km) NWS Omaha/Valley
Prior to the 2013 El Reno tornado, this tornado held the official record as the widest tornado to ever occur.[8][9]
2016 Jiangsu tornado EF4 2.5 miles (4.0 km) CMA, OU, NJU, Weathernews Inc.
This tornado is the widest tornado to ever occur in China and officially is tied as the 2nd widest tornado in history.[10]
1896 Seneca–Oneida tornado F5 2–2.5 miles (3.2–4.0 km) National Weather Service Wichita, Kansas
The tornado averaged 1 mi (1.6 km) mile in width, but expanded significantly to between 2 mi (3.2 km) and 2.5 mi (4.0 km) as it approached Reserve, Kansas, where all but three buildings were damaged or destroyed.[11]
2020 Bassfield–Soso tornado EF4 2.25 miles (3.62 km) NWS Jackson, MS
This tornado was documented by the National Weather Service in Jackson, Mississippi to have been 2.25 miles (3.62 km) wide, setting the record as the widest tornado to occur in the state of Mississippi.[12]
1935 Melbourne tornado F0 2.239 miles (3.603 km) BoM
The Australian Bureau of Meteorology (BoM) documented that this weak tornado was 3,603 metres (2.239 mi; 3.603 km) wide.[13]
2007 Trousdale tornado EF3 2.2 miles (3.5 km) NWS Dodge City
The high-end EF3 tornado had a recorded width of 2.2 miles (3.5 km).[14]
2021 South Moravia tornado F4/IF4 2.2 miles (3.5 km) ESSL, CHMI, CUNI, Meteopress, SHMU, CU, Geosphere, Austrocontrol, BUT
This tornado reached a maximum width of 2.2 miles (3.5 km), setting the record as the widest tornado to ever occur in the Czech Republic and in Europe.[15][16]
1456 Italy Tornado FU 2.0 miles (3.2 km) Chatfield, Machiavelli
A tornado that grew up to 2 miles (3.2 km) wide started as a waterspout off the coast of Italy, came ashore near Ancona, and traveled across the entire country moving from east to west before retreating back into the ocean on the opposite side of the country near Pisa.[17] Niccolò Machiavelli writes a very detailed description of this storm in his book Florentine Histories.[18]
2008 Pardeeville tornado EF2 2.0 miles (3.2 km) NWS Milwaukee/Sullivan
This tornado was extremely wide since the thunderstorm cloud base was very low and the mesocyclone that is usually aloft was well-formed all the way to the ground. Within a broad 1 to 2 miles (1.6 to 3.2 km) wide area of EF0 to EF1 damage, there were several small swaths of EF2 damage due to multiple vortices.[19]
1967 Belvidere tornado F4 2.0 miles (3.2 km) NWS Chicago
The widest significant tornado recorded in the Chicago collar counties. 24 deaths and 500 injuries.[20]
