I try to make my chapters about 20K. Some are 30K. Yes, you try to build to a cliffhangar. One thing that will be different on the Archive is that authors often include a Previously section at the beginning of a chapter to bring the readers up to date. That should go away when you are reading a story as a whole. I edit them out when I submit to the Archive.
Good luck with your efforts. For those of us who can change them ourselves, let us know where you want them submitted. Would the Archive be up and ready to do that?
