The FAST was developed in the UK in 1998 by a group of stroke physicians, ambulance personnel, and an emergency room physician and was designed to be an integral part of a training package for ambulance staff.
âAnonymous. There are no hard-and-fast rules on how long or short a chapter needs to be. It could be three pages. It could be 22. It could be 40. You shouldnât set manuscript guidelines for yourself on chapter length.
The other thing is that chapter lengths are important if you want to keep your book on the straight and narrow, otherwise you'll end up with a tome thicker than a tectonic plate and busting 800,000 words. This is why writers vary chapter length, so they can keep within the 80K, 90K or 100K words of the average novel.
