The further south you go (closer to the equator) the wider the time zone is. The further north (closer to the north pole) the closer together (in miles/kilometers) the boundaries get.
If we lived on a featureless ball the zones would be straight lines from pole to pole 15o apart. Since it is convenient to follow country, state or provincial borders the distance between zones at the same latitude varies both in miles/kiometers and degrees If you lived on the equator it would be roughly 1000 miles wide. the time zone would narrow (in miles or km) the further north you traveled until you reached the north pole, where it would be zero. You would actually be in ALL time zones simultaneously.
