Depends on what kind of aircraft
Deoends on what type of jet you had in mind, and what measurement you're looking for - wingspan, length, etc. The jet aircraft holding the title of world's smallest is the Bede BD-5J, with a wingspan of 17 ft. and a length of 14 feet, 4 inches. The jet aircraft holding the title of world's largest is an Antonov An-225, with a wingspan of 290 feet and a length of 275 feet, 7 inches.
It is the distance from wingtip to opposite wingtip. All aircraft have different wingspan.

There are many different 'jumbo jets' -that is not an aircraft name just a vague description . Most are about 20 feet wide or wider in fuselage. If you are asking about overall size,that is known as 'wingspan' - not width.
The 737 is a big aircraft, weighing about 70,000 pounds and having a wingspan of 93 ft.
The shortest wingspan of a plane is found in the category of ultralight aircraft, such as the Cri-Cri, which has a wingspan of about 4 meters (13 feet). However, among larger aircraft, the McDonnell Douglas MD-500 helicopter has a relatively short wingspan of around 10.7 meters (35 feet). The actual shortest wingspan can vary depending on specific models and designs in aviation history.
A Boeing 747 is a jet aircraft, so this is a strange question.
