Bible reading times

How long does it take to read each book of the Bible? I found the graphic which prompted this post on the blog of Jeff Medders. There are also some fancier versions with the same numbers, an Old Testament one, and a New Testament version. As I was digging around the web researching this post I discovered that the source of the reading times appears to be the Desiring God article Three Tips for Better Bible Reading.

I also found another list with slightly different numbers here (if you click that link it will download the document).

What I have done is to combine the numbers to give a range of time to read each book, which I think is more realistic because we don’t all read at the same speed. Also, I suspect the Desiring God numbers may be a bit optimistic. For some books such as 1 & 2 Samuel, Desiring God only have one number for reading both books so I had to do a bit of an estimate to get the range. In these cases the time for reading both books as claimed by Desiring God is also listed.

I also found a list of the Flesch-Kincaid Reading Grade Level (lower is easier to read) for each book in the ESV (Crossway). The grade level is effectively equivalent to the expected reading level after that many years of school. This is more about how easy or difficult it is to parse each sentence rather than whether the passage is easy to understand. Also note that the algorithm chokes on poetry because it is weighted to assume short sentences are easier to read (hence the book of Job is rated as easy to read!)

12 June 2018 update:

Over the last couple of months I’ve been reading the King James Version of the Bible and realised that another factor that will have an impact on how long it takes to read the Bible is the translation you use. This probably is a reasonably consistent factor across all books of the Bible though so I guess that for some translations like the KJV you could just assume it will always take a bit longer to read than for others such as the NIV.
