Knowing that stable Zr isotopes near the double-magic ${}^{90}\mathrm{Zr}$ nucleus remain spherical, we construct a dispersive optical potential to describe nucleon scattering on zirconium isotopes by introducing linear dependence on mass number $A$ into selected geometric parameters of the optical potential for ${}^{90}\mathrm{Zr}$. Nonlocality of the real potential and isotopic shell gaps are also considered. Excellent agreement with measurements is shown for nucleon-nucleus elastic scattering data of the zirconium isotopes ${}^{91,92,94,96}\mathrm{Zr}$ and also of the natural zirconium.
