Skyscrapers produce great charts because they are long and skinny like the columns in a bar graph. They combine the nerdy attraction of big buildings with infographics and therefore at Oobject we are obsessed with them. Here we have collected a bunch of skyscraper style size comparisons, and not just of buildings, so that you can compare the empire state building with the Titanic, a deep salt mine, space rockets and a neutrino telescope under the antarctic ice.
