The Kármán line is an internationally designated altitude commonly used to define outer space at 100 km (about 62 miles) above Earth's surface.

100 km is accepted as a standard. There is an altitude where the sky appears black whether the sun is in the sky or not, but that happens before 100 km.
The atmosphere thins out gradually, and there are still vestiges several hundred kms up, even where ISS flies. So, it is hard to say specifically where space starts.
100km is probably a good standard, but in reality the only guys who really escaped Earth's aatmosphere completely are the Apollo astronauts who went to the moon.

t3h1 is correct. Space begins at about 328,000 feet or roughly 62 miles above the Earth's surface.
