The ozone layer covers every bit of planet that is lit directly by the Sun. The sun makes ozone from oxygen. That is why the equator sees no thinning except at the poles where the sun doesn't hit it during the winter.
The ozone layer is a few miles / kilometers thick, and has variable concentration with lower values at "top" and "bottom". It cannot have a hard "distance" without nuance in meaning. The Earth's radius at the poles is 6356.8 km, and at the equator 6378.1 km. The ozone layer starts about 10 km above this at the equator, and less than this near the poles. So it starts about 6388.1 km, and ends about 6428.1 km near the equator. 10-50 km + 6378 km near the equator.
Ozone layer contains ozone in it. Therefore, it is named so.
