The Earth's mantle is about 1800 miles thick.
Very good question. Many people have been wondering this, actually. How thick is the Earth's mantle? Well, I did some research and found out that the Earth's mantle is about 1800 miles thick, or 2900 kilometers thick. It contains about 80 percent of the Earth's mass. Wow!
The Earth's mantle has two main layers: the upper mantle and the lower mantle. These layers are distinguished by differences in their composition, temperature, and behavior. The upper mantle extends from the crust to a depth of about 410 miles (660 kilometers), while the lower mantle extends from about 410 miles (660 kilometers) to approximately 1,800 miles (2,900 kilometers) below the Earth's surface.
The radial thickness of the inner and outer core is equal to 3,486 km (2,166 miles). The mantle is 2,885 km (1,793 miles) thick. As such the inner and outer core combined is 601 km (373 miles) thicker than the mantle.

2900 km
Scientists predict the mantle is about 2,900 km (1,800 mi) thick.
The crust ranges from 2 miles to 70 miles(mid-ocean) thick. This is equivalent to 3.225 km to 112.9 km
I say thick because it's got many layers.
The Earth's mantle begins about 6 miles below the oceanic crust and extends to a depth of around 1,800 miles. So, the distance to the Earth's mantle would vary depending on location, but on average, it is about 1,800 miles from the surface.
