What is the largest and smallest virus?

Most viruses are 20-400 nanometers in diameter [1]. The physically largest virus is Pithovirus sibericum, at 1.5 microns (or 1,500 nanometers) in length [2]. Though that might seem tiny, it is larger than some bacteria, and approximately half the width of a strand of spider web silk [3].
