Mice come in a wide variety of colors and sizes. Some common mice colors are white, brown and grey. Some are very tiny and others are around the size of a baked potato.
Mice typically grow from 1 to 7 inches (2.54 to 18 centimeters) in length and weigh between 0.5 and 1 ounce (.23 to .028 kilograms). The African pygmy is the smallest known mouse on the planet. It measures 1.2 – 3.1 inches (3.04 to 7.874 cm) and can weigh less than .35 ounces (.01 kg). These measurements do not include tail length. Some mice have tails that are as long as their bodies.
