I've been to New York a couple of times and San Francisco dozens of times, and I've seen them in maps hundreds of times, but I've never seen maps of them next to each other at the same scale. These two, lifted from Yahoo Maps, are both at the same scale: 44 pixels per mile. They each portray 82 square miles of (impossibly valuable) land and water.

Isn't that neat how Golden Gate Park in San Francisco and Central Park in Manhattan are a similar size and shape?
| Golden Gate is the long green rectangular park second from the top south of Fulton St. It is 3 miles long and ½ mile wide. It was designed by William Hammond. | Central Park is the long green rectangle North of W 57th Street. It is 2½ miles long and ½ mile wide. It was designed by Fredrick Law Olmsted. |
