Which stories felt like they had the better length, and which ones felt like they were too long? What's a good word count/length for sitting down to read a chapter or two at a time?

I'm gearing up to start breaking one of my longer stories into chapters/parts, and I want to figure out what's a good length for the chapters. Like, I'm not gonna make you sit down and read a 10,000 word part in one go, but is 5,000 or so words a good length for a longer multi-part story? Is 1,000 too short, or do you prefer that length?*

The reason I'm asking about words and not page length is because everyone's going to see things a little bit different. So, when I say I've written a ten page story, for example, with my settings that's ten pages at size eleven Helvetica, no extra spacing. And that's about 6,500 words. Okay, so that probably tells me that that's TOO big of a chunk of words…

Anyway, thanks for any replies you give me! I look forward to them.

PS: Also, can FA even show tabbed sentences in txt documents? My computer shows them, but I have no idea if FA can even handle the awesomeness that is


*please don't say you prefer this length because it will take me FOREVER to post this story that way
