2,890 km
the inner mantle of the earth is aproximatly 2850km thick.
the mantle is more than 16000 miles, and is the thickest layer of them all
it's 410km to 660km thick
The Earth's mantle is about 1800 miles thick.
The mantle is found between the core and the innermost layer of the earth. The mantle is made up of mostly solid rock that is 1,802 miles thick.
The Earth's outer core is thicker than the mantle. The outer core is about 2,260 kilometers thick, while the mantle is approximately 2,900 kilometers 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!
Earth's mantle is about 1,800 miles thick.

Scientists predict the mantle is about 2,900 km (1,800 mi) thick.
