Bond strength of molecules

When given two molecules that each have varying numbers of both single and double bonds how do you find out which molecule has greater bond lengths?

If the molecule has resonance structures then the molecule with a greater number of double bonds will have shorter bond lengths. This is because with resonance structures the real bond length is a hybrid of both the single and double bonds (or any other combination), so structures with more double bonds will have overall bond lengths closer to the double bond length.
