Learning a new language takes time, and how long it takes, exactly, will vary depending on how similar the language is to the one you speak. This infographic tells us how long it takes English speakers to learn the nine most common languages in the world.

The graphic is sorted by easiest to most difficult. It also tells you how each language is ranked, according to how many people speak it, globally, as first language. As you might imagine, Chinese is the most common first language, and it takes English speakers roughly 88 weeks to learn it. The second largest first language -- Spanish -- typically takes only 23 weeks to learn.
It should go without saying that your own time will vary. The numbers are based on information from the The Foreign Service Institute (FSI), and they assume about 25 hours a week spent learning each language. You can find more detail on their website.
