I like for the chapters in a story I am reading to be about the same length. That tells me how much time I have to budget to read a chapter without having to look it up. I appreciate the convenience.
That's how I used to approach it, aiming to give my SOL readers the most 'bang for their buck' for each chapter. But I've since migrated to differing sized chapters. If the action is fast and furious, I'll write short chapters, since a lot happens in fewer words (say only 2,000 words). If I'm describing details (like how a particular technology works), I'll write a longer chapter (as much as 10,000 words). My initial chapters tend to be longer, as I introduce characters, situations and conflicts (though shorter, faster chapters would probably sell the story better). Once those details are covered, the chapter lengths slide back to normal.
When I run into trouble is when I try to describe everything that happens in a given day, or at a give time. Then there's an artificial time frame imposed by the story, and it's difficult pacing it out.
Perv, I didn't mean to put any words in your mouth, but that's what I'd thought you were saying. However, I agree with Switch in that I don't think book chapters should all be the same length. Different types of chapters should fit into distinct categories. Likewise, when I read (a print book), I'll often look at the page length of the chapter before committing to reading it before I go to bed. That's a longstanding reading habit of mine.
Chris, as I mentioned in the other thread, that was my understanding about the Romance genre (that they prefer fast reads that get them to the romantic ending quicker), but I researched it later and discovered my info. was dated. Most Romance books found in book stores are now fairly sizeable, which means Indie books will tend to be even larger, since they're unconstrained by paper costs.
By the way, I agree with Switch. I now write book chapters, and will post multiple chapters to reach my magic SOL posting size of 5,000 to 6,000 words. (If you go over 8,000 or 10,000, I forget which, it breaks into multiple SOL pages!)
