I think I just realized it takes six hours to get from one side of the czech republic to the other assuming it’s as big as IL. We are indeed huge for a single country as opposed to a continent.
Contiguous USA (8,082,000 km^2) is still bigger than Australia (7,687,000 km^2) by 395,000 km^2 (152,529 square miles) The area of Europe varies on your definition: Are you looking at the countries of Europe, or are you looking at the furthest borders of the continental plate?. Wolfram says that the total area of European countries is 5,968,000 km^2 (2.3 million square miles), making it smaller than the contiguous USA. Your numbers are from Wikipedia, and they include all of the area up to the Ural mountains, which adds in Turkey and parts of Russia. Those two countries are trans-continental, so it is debatable where to draw the bordering lines.
