Mike Wazowski is generally estimated to be about 3.5 to 4 feet tall (roughly 1.1 to 1.2 meters).

Why it’s an estimate

There is no official, canonical height for Mike published by Pixar or Disney. Fans and analysts estimate his height by comparing him to Sulley (who is usually put around 7 to 8 feet tall) and to human-sized doors and objects shown in the movies.

Common fan measurements

Most fan analyses cluster around a specific range:

• Around 3 feet 6 inches to 3 feet 8 inches tall.

• Some discussions narrow it to about 110–115 centimeters when scaled against standard door heights.

So, a good concise answer is: Mike Wazowski is roughly 3½ feet (about 1.1 meters) tall.
