They are bigger because the Outer Planets had less gas and dust taken away from them when the solar system was forming. The Inner planets were closer to the sun, so the sun took more gas and dust away from those bodies, but didn't take away from the Outer bodies.

the outer planets are gaseous and the inner planets are not
What is the relative size of the inner planets?
The inner planets are smaller than the outer planets. This may be because the outer planets are called gas giants. This means that gas can accumulate in size at times, and this can be one of the situations.
