What Hannah said-- the larger the surface area between two molecules, the greater opportunities to induce dipoles and have LDF interactions. This makes more sense for linear molecules. If you put two pencils together, they would touch at a greater surface area that if you put two ping pong balls together.
London dispersion forces are also greater as the size of the atoms/molecules get bigger. The bigger atoms have higher polarizability, will become distorted more easily and create stronger London dispersion forces. This explains the difference in boiling points as well.
