How many pages to print the Internet?

How many web pages make up the Internet? It’s not an easy number to calculate. A team of Dutch scientists published a paper describing one estimate method that uses word-count frequency in search results. Applying their method to the Google search index, they estimated that there are around 47 billion web pages.

Assuming the average length of a Web page is 6.5 printed pages, then it would take 305.5 billion pages to print the Internet. This is roughly the same number of pages as 75 million copies of the seven-volume Harry Potter series.

Looking at it another way, if each of these 47 billion web pages was a book, the Internet would be more than 1,200x larger than the 38 million books and other print materials in the U.S. Library of Congress, the largest library in the world.
