Planets size
If we can joint all the planets (including Pluto) around the Sun we will see something like the next image.
In this image the planets are represented a scale of size, so you can compare easily their relatives sizes.
As you can observe the inner planets are very small compared with the outer planets (excluding Pluto).

Feel free to construct your own Solar System Model using this scale (or other that you want) as reference !!
As WIKIPEDIA states :
Terrestrial planets
A terrestrial planet, telluric planet or rocky planet is a planet that is composed primarily of silicate rocks or metals. Within the Solar System, the terrestrial planets are the inner planets closest to the Sun. The terms are derived from Latin words for Earth (Terra and Tellus), as these planets are, in terms of composition, "Earth-like".
Outer planets
The outer planets are those planets in the Solar System beyond the asteroid belt, and hence refers to the gas giants, which are in order of their distance from the Sun:The outer planets all have ring systems, although all but Saturn's are faint. Another aspect common to the gas giants is their many natural satellites.
