Parameterization of the form factors of f1(1285) meson is proposed. This parameterization is consistent with the available experimental data on the cross sections of f1(1285) meson production in the processes e+e−→f1(1285) and e+e−→e+e−f1(1285), as well as on the widths of the decays f1(1285)→e+e−, f1(1285)→ρ0γ, f1(1285)→ρ0π+π−, and f1(1285)→2π+2π−. Our parameterization is also consistent with the predictions for the asymptotic behavior of these form factors.
