A theoretical model to approximate subatomic particle sizes is proposed. The model draws inspiration from particle-antiparticle creation-annihilation processes. In the proposed model, collision of photons gives rise to particle-antiparticle pair with physical properties that the pair possesses: electric and magnetic properties arising from the electromagnetics of the photons, and the mass from the warping of the geometry of spacetime by the electromagnetic energy density of the photons. Results of the approximations of different particles’ sizes are compared with experimental values and those obtained from other theoretical models.
