Why San Francisco is not 7 by 7 miles

January 15th, 2014

San Francisco is seven by seven miles. Everyone who lives here knows that. There’s even a magazine named after this fact.

Problem is, it’s not exactly true.

While the land area is about 49 square miles, as Wikipedia points out the total area is a much larger 232 square miles when you include water. Aside from a sizable portion of the bay and some of its islands, San Francisco also includes the Farallon Islands and surrounding water in the Pacific.

The city’s actual borders are easy to visualize using OpenStreetMap:

In case you’re wondering where OpenStreetMap is getting this data, it’s straight from the US Census TIGER data. The same information can be viewed on their website, albeit with some difficulty.

One more thing: (Spoiler alert!) Despite what many seem to think, SFO is not located in San Francisco; it’s entirely in San Mateo County. So if you’re ever wondering why the airport doesn’t have SF’s trademark urine, pot, and beer smell, that’s probably why.
