Mine vary depending on the story. The project I just finished was anywhere between 1300 and 2000 words per chapter. Short chapters because I'm spectacularly lazy and like to use chapter breaks as scene breaks or POV breaks. The entire story ended up being fairly short, only 31,700 words. My current fanfiction is so far averaging around 2600-2700 words per chapter, which is a big improvement, but still relatively short. What this means, however, is that if I write 20 chapters for this story and keep all the chapters around this length, I will approximately double my word count for the completed story. And I intend to write more than 20 chapters. This one will be significantly longer, I think, if I can finish it. So how many words per chapter do YOU average?
