With a diameter of 3,474 km, it is about 1/4th the size of the Earth. Translated into miles, that is about 2100 miles, which is about the size of the United States.

The volume of the Moon is 2.195 x 1010 km3, which is only 2% of the volume of the Earth. You could fit 50 Moons inside the volume of the Earth. The mass of the Moon is 7.347 x 1022 kg, which is about 12% of the mass of the Earth.
