Bacteria Vs Virus Size. A microscope is required to see viruses and they are 10 to 100 times smaller than the smallest bacteria. Bacteria are giants when compared to viruses.
Viruses are usually smaller in seen and are observed using an electron microscope. Viruses are about 1 000 times smaller than bacteria and are visible under an electron microscope. Therefore in general smaller viruses can be over 200 times smaller when compared to some bacteria.
Bacteria are giants when compared to viruses.
Virus bacteria differences viruses are the smallest and simplest life form known. The smallest bacteria are about 0 4 micron one millionth of a meter in diameter while viruses range in size from 0 02 to 0 25 micron. Larger 1000 nm smaller 20 400 nm 2. They have a size of about 20nm to 1000nm maximum.
