Question: When should one chapter end so that another can begin?Answer:
There are no hard rules about this, but here are a couple of guidelines that may help...
1. A chapter should be a length that is comfortable for a person to read in one sitting, rather like a short story. Obviously, this varies with the readership. Children need shorter chapters than adults, for example.
2. A chapter should end when one event has been resolved, but resolved in a way that sets the stage for the next event, so that the reader is looking forward to what happens next. In other words, you want your reader to be tempted to read one more chapter.
3. Bear in mind that not every chapter needs to be the same length. Sometimes a little variety is appropriate.
