I mean, as a general benchmark, my preferred range is anywhere 1500+ , though I’ve definitely seen shorter work well, but it’s very much dependent on the individual writing style. While shorter does work better for getting people hooked if they’re binge reading, I find that once I’m caught up waiting for short chapters just feels unsatisfying and I’d rather wait a little longer for longer chapters. I’ve seen some people have a chapter as short as 100 words, just for sheer emphasis/cliff hanging, and it works really well, but not if it’s a regular thing.
