Here's how I computed the average height of a country. I represented each country as a grid of 2500 points. Then, for each point, I calculated how far you could travel in a straight east-west line without leaving the country. The average width is the average of these distances.

This is an interesting way to deal with the problem of anomalous parts of a country affecting its height/width ratio (consider Namibia for example). When I read the description I assumed that you hadn't thought the methodology through - if you are using the arithmetic mean of the widths over all latitudes then average width = area/total height, and average height = area/total width, so average height/average width = total height/total width. Using what is approximately a root mean square is a good way to sort this out (though I would just have used a root mean square). However I am a little sceptical as to whether methodology is working. The ratio for Chile seems like it should be more like 8. What happened? I am also wondering how it treats countries that are large collections of islands. The ratio for Indonesia (I suspect) would be quite close to 1 using your methodology but it feels like it should be less.

Is it TOO thin and you're quickly out of the country when traveling north-south?

Southern Chile has a very ragged coastline with lots of islands. You probably couldn't go very far horizontally or vertically from many parts in that area of the country.

Update: September 14. A previous version of this quiz had incorrect numbers due to an Excel spreadsheet error. For example, the number for Chile was only 2.33. This has been fixed now.

Interesting methodology. Floored to see that Myanmar made the list, but not Vietnam. Using the looking at a map and guessing version I would have expected the opposite!

No Norway ?? That's really surprising...
