It just looks skinny because of how long it is baby I promise it's more than thicc enough for you 😏

I feel like this is stretching the definition of "thin" to make sure nobody feels insecure about the proportions of the land claimed by local government.

What are we doing here, folks?

It's not very thick, it is thin, but it's extremely long. Chile that is.

Not many countries outside of Europe are as small east-to-west as Chile. Even in Europe the major countries like France, Germany, Spain and even the UK are bigger east-to-west. Italy is bigger east-to-west, but mostly because it's angled. If it were oriented vertically like Chile it would be thinner along most of the boot, but still wider than Chile along the top from the coast near Nice to Venice.

Also worth noting that although the UK isn't all that wide, it has major port cities on both east and west coasts. Chile has an inhospitable mountain range on its eastern side, so really the population is concentrated in an area that's much thinner than the geographic boundaries of the country.
