When comparing the size of the Earth and Moon, volume or mass can be considered.

From Wikipedia for Earth:

Volume 1.0832073 × 10^12 km^3

Mass 5.9736 × 10^24 kg

From Wikipedia for Moon:

Volume 2.1958 × 10^10 km^3

Mass 7.3477 × 10^22 kg

With some simple calculations:

The Earth has just over 49 times the volume of the Moon.

The Earth is over 81 times as massive as the Moon.

Clearly the Earth is also a lot denser which must be because it has collapsed under it's stronger gravitational field due to being more massive.
