How High Do You Have To Be To See The Curvature Of The Earth?

Curvature of the horizon

A curvature of 1.0 appears as a circle of an angular radius of 57.3° corresponding to an altitude of approximately 2,640 km (1,640 mi) above Earth’s surface.

How far can you see curvature of earth?

Earth’s curvature

The Earth curves about 8 inches per mile. As a result, on a flat surface with your eyes 5 feet or so off the ground, the farthest edge that you can see is about 3 miles away.
