LOL I literally just answered your other question! But yay for a two-fer!
I do pay attention to length when I write just because I like to keep my chapters at least within the same range... like, I wouldn't want a story to have Chapter 1 be 900 words, Chapter 2 be 10,000, and Chapter 3 be 4,000. I try to keep them a little more equal than that. The range varies from story to story, but 2,000-5,000 words or 4-10 pages on Word pretty well covers it.
That said, if I have to go longer to finish a scene or post a short chapter because I have nothing else I need to say, I will. I like my chapters to start and stop in a place that makes sense. They're usually about one thing, like a certain event or maybe just a certain theme or idea. Sometimes they're one long scene, sometimes several shorter scenes that hopefully flow together. In a story with just one main plot told in one point of view, it doesn't matter as much where one chapter ends and the next begins, but most of the stuff I've been writing lately has multiple points of view, so it takes more planning to decide what all I need to include in one chapter before switching perspectives in the next. That's usually what leads to some chapters being significantly longer than others.
