strings are very small, so how many make up 1 electron since the size and mass of the electron is on a bigger scale to these strings?

strings are meant to exist at the small scale of the planck length, yet objects such as the electron, which is composed of one string, exist at a much bigger scale in size and mass. how is this possible?

    May 2 2012: As obey says the electron is the total space taken up by the oscillation of the string and the mass of the electron is mainly in theform of kinetic energy due to the oscillation. e=mc2 so m=e/c2 ie energy has mass. An analogy (take a length of rope and roll it into a coil, how big is it? now hold it by one end and swing it aroung above your head. Now how big is it? The space occupied by the rope depends on what the rope is doing.
