Methodology is averaging the rank of the sizes.

Russia is rank 1 in the world by land area and China is rank 3. So the average of the two is 2.

Likewise Canada=2 and USA=4; Average=3

Sometime between late 2017 and now China overtook Canada as the second largest country, so it's now 1.5 and 3.5 for those examples.

This probably includes inland fresh water, but excludes non-freshwater internal waters. By which measure Canada is larger, China is larger when it is purely measured on land, but I’m not sure how Canada would feel about having its lakes left out. They are ‘Great’ after all…

I misunderstood the methodology as well (thinking the length of the border was important) and asked myself the same question. But now that I get it Chile is definitely out of the picture. I mean it's not thaaaaat big of a country even though its elongated shape makes you think otherwise.

I personally don’t really like this quizzes size methodology, since I personally like the measurements of countries by land area and internal lakes and rivers.

But still good quiz, I almost missed China and Pakistan.
