Under the framework of the vector meson dominance model (VMD), the absolute scattering lengths of light vector mesons (ϕ, ω, and ρ) with the deuteron are calculated from the cross sections of vector meson photoproduction off a deuteron. Additionally, a fitting function is used to predict the scattering lengths of the heavy vector mesons J/ψ-d and % Υ-d. Based on these results, the distribution of the scattering lengths |αV d| between vector mesons and the deuteron is presented for the first time and compared with the scattering lengths |αV p| between vector mesons and the proton. It is found that as the mass of the vector meson increases, the scattering lengths |αV d| become closer to |αV p|. In addition, the correlation analysis indicates a strong positive relationship between the scattering length and the vector meson radius, with a high correlation coefficient. The implications of results are essential for improving our understanding of the interaction between hadron and nucleus.
