They vary significantly depending on the type of virus, however, viruses are sub-microscopic and require an electron microscope to visualize and very very tiny compared to the size of bacteria.
For example:
The Swine Flu viruses (including Novel H1N1 2009 Swine Flu) are very similar in structure to all Influenza Type A viruses. They are also very similar in size to most viruses.
They are about 1/100th the size of bacteria. Most are "nano" size and too miniscule to be seen with a regular light microscope, so electron microscopes need to be used to visualize the virus particles.
When measured they have a diameter of 10 to 300 nanometers. The nanometer is equal to one billionth of a meter, or one millionth of a millimeter.
The diameter of a typical cold virus ranges from about 20 to 30 nanometers.
The influenza virions have envelopes and occur in pleomorphic and filamentous forms. In general the virus's morphology is spherical with particles 50 to 120 nm in diameter.

How does the herpes virus that causes cold sores infect host cells differently than a cold virus would infect host cells?
The herpes that causes cold sores remains in the nervous system and is reactivated from time to time. The sore reappears at this time. A cold virus doesn't act this way in the nervous system. Once a person has a cold, that person makes enough antibodies so that the virus doesn't cause a cold again in that person.
