Many of us eat fast food every day and think nothing much of it. We just need something cheap and filling to get us through our meal. Have you ever wondered the actual size comparisons between fast food served in the United States compared to other countries?

YouTubers Rachel and Jun decided to do a little experiment to see if there was any noticeable  contrast between a variety of iconic fast food items in both countries.

Check out the size comparisons video and see for yourself

While there were a few minor differences between fast food burgers in calories and price, the one major variance was the size of American soft drinks. A large in America is about double the size of a large in Japan. In fact, the YouTubers pour the contents of an American soda cup to fill a Japanese large and medium.

Watching this video really makes us reconsider ordering a large soda the next time we get some fast food. Perhaps we'll just stick to the free water cup.
