The diameter of the Moon is 3,474 km. Need some comparison? The diameter of the Earth is 12,742 km across. That means that the Moon size is roughly 1/4th the size of the Earth.

Depends, of course, on what you mean by size. If the diameter is roughly 4 times as large, the surface area will be about 16 times as large (4 x 4, for an area comparison), and the volume 64 times as much (4 x 4 x 4 for a volume comparison).
