I completely redid this quiz. As several people pointed out, the Wikipedia source is extremely poor. I spent a couple hours computing the coastlines myself, and got results which make a lot more sense. You can read more here. As far as I know, my list is the only accurate source for state coastlines that exists on the internet.

There is no correct lenght of any coastline. Read about coastline paradox

Why exclude coastline from lakes? Michigan has the second most shoreline of any state (behind Alaska). I don't understand the logic.

In the last version, before the correction mentioned above, I think I remember Oregon was there but not Washington, which did seem strange to me.

I found it hard to believe that Maryland has more coastline than Oregon, but Oregon's coastline is pretty much a straight line and Maryland has the Chesapeake bay, so I guess it makes sense.

I was surprised too, then I realized that Washington and pretty much everywhere else had all of those bays, islands, and peninsulas.

Hawaii is pretty small, but according to QM's data it's #11.

Love the quiz. What about Michigan? More than 3,000 miles of coastline.

Michigan's borders do not stop at the edge of the lake, it includes much of the water as well, so it doesn't really have any coastline.

Thank you for the tremendous effort in redoing the quiz. It is heartening to know that some quizzers aim for accuracy to inform and educate.

this should include lake shore lines. No one outside the great lakes area knows how massive these lake are and how long the coastline of Michigan really is. ITs longer than the eastern seaboard!

A message to everyone who wants Michigan included and every other lakeshore state: The quiz says longest coastlines, not shorelines. A longest shorelines quiz is what you want if you want ocean and lake, but that's not a coastline!
