Viruses can vary pretty widely in size depending on the specific type of virus. All are sub-microscopic, and the only way to see them is with an electron microscope since they are measured in nanometers. Influenza viruses vary in size from 10 to 300 nanometers. The nanometer is equal to one billionth of a meter, or one millionth of a millimeter.
See the related question below for more about the size and shape of the Swine Flu virus for an example.
Roughly 120 nanometres
100-120nm in diameter
AN HIV virus diameter is 1000 miles
the nucleic acid and capsid of virus are in the head and they help also grow the virus
Head is the Circumference which is Pi*Diameter where pi=22/7
60 - 220 nm in diameter.
The size of a pin head is roughly two mm in diameter. The size of a sewing needle head is roughly five mm in diameter.
