A student asked, “How do you know where to put a chapter break?”
Short answer: vibes.
Grouping and separating ideas is a large part of writing. Sentences, paragraphs, scenes, chapters, parts I and II of a book, books in a series—all are choices about what belongs together.
Andri did this, and Banti did that.
Here, two independent clauses are joined into one unit with that comma and conjunction. We don’t have the surrounding context, but maybe those two acts are being performed simultaneously. Or maybe the second was enabled by the first. Either way, grouping them together in the same breath implies a relationship.
Andri did this. Banti did that.
Putting a period between them creates a separation. They’re adjacent but no longer joined. First one, then the other, not at the same time. This follows that, but not necessarily as a direct result.

Move them to separate paragraphs and the only relation might be that they’re taking place in the same setting. The characters might not even be aware of one another, and this is just the order in which the POV source observes them.

With a scene break between them, they might be on opposite sides of the world at different points in time, the only connection the author’s choice that you read about them in that order.
Chapters create still larger separations. Chapter breaks are such a hard stop between two sections of text, they’re generally recognized as “a good place to quit for the night.”
Chapters can be single scenes or contain multiple scenes that work together as a group. The connective tissue binding those groups varies from book to book. In a book with multiple POV characters, Character A’s scenes might be separated from Character B’s scenes by chapter breaks. A group of scenes might take place in one location, the chapter break indicating a jump to a new location. Chapters might mark time division (Monday, Tuesday) that could encompass any number of characters in any number of locations. It could be a subtle grouping, such as characters independently working through some common element of the theme. The uniting factor is up to the author.
There isn’t a rule about where to stick a chapter break. Sometimes the final line of a scene is a clear dun-dun-DUN that demands the rest of the page to itself, so you have to give it a chapter break even if it doesn’t fit the pattern you’ve used for the rest of the book. Charlie Huston’s Joe Pitt Casebooks achieve their nonstop pace, in part, by skipping chapter breaks entirely. (Which I noticed only after promising my small, hungry child I’d start dinner as soon as I finished the chapter. Two hours later…) You have to make a creative decision about where you feel this inkless punctuation belongs.
Don’t worry too much about where those breaks go while you’re writing the rough draft. A rigid framework can make you more reluctant to make big revisions for the good of the story. When you’re happy with everything else, then consider where a dramatic stop makes the most sense and has the greatest effect.
And then, if you want to take your chapter-making a step further, look at the group you’ve created and think about a thread of unifying language you can stitch through that group from beginning to end. If the final scene of the chapter takes place at orchestra practice, can the birds in the first scene be piping and trilling rather than chirping and tweeting? If the final scene of the chapter is a sword fight, can you replace the fruit stand they stroll past in the first scene with a fishmonger gutting a trout? Or maybe you want the contrast of the pleasant fruit stand before the bloody battle, so during the latter, blood droplets are spraying red and gleaming like pomegranate arils. This is extra work, but it reinforces the bonds of the group you’ve chosen and helps transmit the vibes behind that decision to your readers.
