Metro area by diameter

Not sure but might be that LA is the biggest agglomeration in the world. That land is insanely huge, you could easily have 100 million ppl living in that enormous area.

Chicago is around 150KM from the northwest side down into Indiana.

Although if you got in your car and drove from the far northwest suburbs over to around Michigan City, Indiana, it would be a 205KM, and take over 2.5 hours without traffic.

Where did you come up with 150 km :dunno:, it's 120 km tops, you can measure it on GE. In addition there are much more holes with no urban space in Chicago metro. LA conurbation on the other hand is all connected and as I said, it's too too big hno:.

Not sure where you get that idea from.

This map shows 160km as a fairly generous diameter of Tokyo.

The city where I live, Auckland in New Zealand, must be one of the longer cities in the world with a population of "only" 1.3 million:

According to http://www.citymayors.com/statistics/largest-cities-area-125.html its the 7th largest.

To "easily" fit 100 million people in that area would require a density of 23,148 people/sqkm.

LA is not that big, especially for its population. There are over 14 million people living in an area that is 2,300 sq. mi. (That's less than 6,000 sq. km in area.)

Bay Area, its quite long and San Jose to Santa Rosa would be about typical spread of Bay Area although, it goes further out north and south

Hartford.

I know that it's nowhere near the biggest, but this is an interesting topic, and I want to share my city.

The city proper is within the black. It's small. Around 4km east-west, and 8km north-south. Literally at times, you can walk or bike to the other side of town in no time.

Everything within the yellow is my rough estimate of the urban area. There is about 550-600k in the area (the metro area as a whole, which incorporates massive area, is about 1.3m). It's more sprawling.

The metro stretches west to east more. Almost 45km. I would say that there is an (almost) unbroken trend of development from Bristol to the west, to about Tolland/Vernon to the east. North-South is about 33km or so. From the hinterlands of our airport to the northern reaches of Middletown, a satellite city of Hartford.
