I am currently writing a Sci-fi Fantasy series. At the moment, I am writing the first book of the series that I call the Aeon Scars. I have made a rough backstory that I intend to write as a prequel, but only after I have established the tale. I also made a prologue, which has a pace of its own I believe. It serves as an introduction to the world the readers so that they are not forced to find a glossary of terms. Buuuuut, maybe none of you needed to know that. Forgive me.
So, let's get to the point. I have concerns on how long exactly a chapter should last. Me being 3 chapters in, I feel like the pacing of each chapter goes fast and then slow at certain areas. There is an average of 2,500 words per chapter. I was thinking of expanding certain scenes and removing some unnecessary bits for the sake of keeping the reader engaged. I know that the only person who could really tell how long the story is going to be is me. But the only challenge I face is how can I keep the readers engaged.
TL;DR I want to ask you, as a fellow writer. Approximately how many words or paragraphs does a chapter need in order for it to not seem too slow or too fast? I acknowledge that I am the one in charge of pacing in each chapter. But I'd like to survey you folks on how many words a chapter needs in order for it to feel like a chapter. I just need a rough estimate so I can precisely end my chapters with confidence.
Feel free to call me a bit of a hypocrite, since I honestly haven't read a lot of books. Why I think this is relevant is because I believe that being an avid reader can really help you become a decent writer and I am absolutely not that kind of dude. That is why I came here to ask for your thoughts. I'm more of a comic and video game type of guy. I love stories and various narratives, which is why I wanted to write a book. Any help is appreciated!
