If LDFs are supposed to be commonplace and weak, how can they be stronger than dipole-dipole interactions?

In larger heavier atoms/molecules, there are more polarizable electrons causing the LDFs to be so strong that they can be even stronger than dipole-dipole forces.

The size of the atoms/ molecules have to be taken into consideration as well, not just the forces.

If a molecule has many atoms with high polarizability, the LDF can actually be quite strong.

Larger molecules with many electrons and a greater surface area can be capable of being stronger than dipole-dipole forces in limited cases.

In the case of a bigger atom, there are more electrons so the greater area can mean that London Forces are stronger than Dipole-Dipole
