i believe that they are 50-90 nanometers (nm)

The mature virus has a bullet shape, a protein coat, and a lipid envelope. The outer surface of the virus is covered with thumblike glycoprotein projections 5-10 nm long and 3 nm in diameter. The virus averages approximately 780 nm in length.
60 - 220 nm in diameter.
0.05 micrometre.
nanometers, billionths of a meter.
50 nm = 0.05 micrometer
Viruses generally range from 20 nanometres to 300 nm in diameter although the largest can be as much as 500 nm. Their lengths range from 700 to 1000 nm.

Virus is a pathogenic agent with an outer protein coat with nucleic acid molecule inside, and multiply only within host living cells. Size varies among different classes of viruses. Most viruses vary in diameter from 17nm (porcine circovirus) (nm; 0.0000008 inch) to 500 nm like Herpes simplex virus-I (125nm) or HIV-I virus (120-150nm); the largest, however, measure about 500 nm (mimi virua, Pandora Virus) in diameter and are about 700–1,000 nm in length. only large viruses can be visualized under normal microscope.

Bacteria are unicellular organisms that are a few micrometers long and have many shapes - curved rods, rods, spiral, spheres. Virus us a sub-microscopic particle ranging in size from 20 nm to 300 nm.
