The electromagnetic form factor of meson has been investigated by utilizing twisted mass lattice quantum chromodynamics gauge configurations. In order to increase the resolution of the electromagnetic form factor in the momentum space, we make use of the twisted boundary condition to compute corresponding correlations for meson. The electromagnetic form factors with more small four-momentum transfer were extracted, and the charge radius were further fitted. This work provides useful information on the electromagnetic form factor of meson.
