Generally strong bonds are more polar. (Ionic bonds are stronger than covalent bonds). Therefore, the more polar bonds tend to be shorter in length? And yet, the dipole moment is the product of charge and distance, which implies that the longer the distance, the more the polarity?The bond length show one feature also that is multiple bond is shorter than the corresponding single bond between two atoms: This means the triple bonds are the shortest of all bonds amoung second-row elements. To summarize the following factors influence the bond lengths: The smaller the atoms,the shorter the bond.
