I’ve long been interested to get a scale for the various cities I’ve either grown up in or love visiting, but it never occurred to me to just do a simple OpenStreetMap comparison:

Maps showing cities listed above.

From top left to bottom right we have:

  • Sydney, which just fits
  • Five boroughs of New York City, with a bit of New Jersey
  • Tiny, tiny Singapore with Johor Bahru across the Causeway
  • Hong Kong, which is closer in size to Singapore than I realised!
  • Klang Valley, with Kuala Lumpur and Putrajaya
  • Kansai Region, with Ōsaka and Kyōto

I checked Tōkyō, and it would have covered almost all six squares. I’ll bet some cities in China would be similar.
