Summary: The Mercator projection is usually presented severely truncated in atlases, for obvious reasons as the earth is mapped onto an infinite strip. Surprisingly though a fairly modest truncation accomodates all of the earth except two coinsized regions at the poles. In fact such a truncated map will be presented with the upper and lower extremes of the rectangle are scaled $1:1$.
