To calibrate instruments using polystyrene particles as a reference size material, it is necessary that the sizes of polystyrene particles are measured accurately, however, we have sometimes experienced that there are differences between manufacturers' nominal sizes and actual measurement values.
 Size measurement by Transmission Electron Microscope (TEM) photographs has commonly been used, but, it has not been under proper control.
 Magnification errors, growing or shrinking of particles have been among those problems. We have developed a measuring method of particle size, and in this paper, the method of measuring the particle size of polystyrene particles by a TEM and exact sizes of polystyrene particles are reported.
