Book Length

Hi there! What are your parameters for short or long books?
What about short books at 6 hours or less, and long books 20 hours or more.
What do you all think? Thanks!

In AZ, we have our short books as anything under 6 hours, and anything over 12 hours for long. (This is a holdover from the cassette days, and is the equivalent of 1 cassette tape for short, and 3 or more for long.)

For MA1A, anything 5 and under is short, 15 and over is long. We were saying 10 and over for a while, but that really limited the options for folks.

In OR we use < 6 hours as Quick Reads, 6 - 9:59 as short length, 10 - 19:59 as a medium length book and over 20 as long length.
