Errrrr… Three-quarters of the Earth's atmosphere is reckoned to be within the troposphere, which is anything from 7 to 17 km deep. Or high, if you prefer. But the furthest extent of it is up to 10,000 km altitude (although the Karman Line at 100 km (1.57% of Earth's radius) is often considered the boundary between Earth & space). The Earth's diameter is, of course, roughly 12,700 km.
I am clueless as to what point you think you are making, Don. But I think you've got it wrong! ;-)
