My first chapter was 36 pages. I didnt want it to be shorter than 20 pages, but I also didnt want to drag out the contents of Ch 1 longer than I needed to. My 2nd chapter- which I'm currently working on, is going to be 40 pages- I had to get a bunch of story material out there to further perpetuate the story. For the most part, I'm gonna try to keep my chapters between the 30-40 page range; that way it wont seem too long, or too short- I feel like that range would be manageable enough for me.
