Maybe you're planning your reading material for a flight, or maybe you just want an idea of how long it will take to get through your reading list. Whatever the scenario, How Long to Read This tells you how long it takes to read any book.
You can look up over 12 million books (all of the popular titles are in there), and the site will give you details on how many pages it is, how many words it is, and what it's about. Just enter your book, and you'll take a quick reading test. This test offers an idea of how many words per minute you read, and based on that number, the site then tells you approximately how long it will take you to read that particular book.
Of course, this estimate is just based on the simple test you're presented with, so it doesn't account for distractions or rereading certain paragraphs to retain the information. It's not exact, but it's a good approximation. Give it a try at the link below.
