Scene breaks, ellipses, and dashes: the typography conventions fiction uses

The short answer: a scene break is a blank line or a centered ornament, and ornaments exist because a blank line vanishes at a page turn. Use an em dash for interruptions, an en dash for ranges, a hyphen for compounds. Style ellipses one way and keep it. Always curly quotes, never straight. A double hyphen standing in for an em dash is the tell that gives an amateur file away. Details below.

Scene breaks, and why ornaments exist

Within a chapter, a shift in time or viewpoint is marked by a scene break. There are two conventional ways to set one:

Here is the problem that decides between them. A blank-line break becomes invisible when it falls at the bottom or the top of a page, because the reader cannot tell the blank from the ordinary space that ends a page. They read straight across the break as if nothing happened, and the scene shift is lost. This page-turn invisibility is the entire reason ornaments exist. Sound typesetting uses a visible ornament wherever a break lands at a page edge, and many designers simply use the ornament for every break so the reader is never left guessing. Whichever you choose, the ornament and its spacing should be identical every time it appears.

Three dashes, three jobs

The dash family is where careful fiction shows its hand, because three different characters do three different jobs and they are easy to confuse:

The em dash is the workhorse of fiction: it cuts a line of dialogue off mid-word, sets off an abrupt aside, and marks a sudden break in thought. The en dash quietly handles ranges and spans. The hyphen stays home joining words. Reaching for a hyphen where an em dash belongs is one of the most common tells of an unedited manuscript.

A note on 2026 practice: some houses now set the em dash with thin hair spaces on either side rather than tight against the words, which opens the line and reads a little softer. That is a legitimate house-style choice, not a rule, and both the tight and the spaced em dash are correct as long as a book commits to one.

Ellipses: pick a style, keep it

The ellipsis marks a trailing off or an omission, and there are two ways to set it. One is a single ellipsis character. The other is three periods with thin spaces between them, which gives a typesetter finer control over how the dots sit and how the line breaks. Both appear in professionally made books, and the choice between them is house style rather than a matter of correct and incorrect.

The real error is inconsistency: a book that sets a tight three-dot ellipsis in one chapter and a spaced one in the next looks careless even to a reader who could never articulate the difference. Consistency beats ideology here, as it does with the spaced-versus-tight em dash. Decide once, apply everywhere.

Curly quotes, always

Typographic quotation marks curl toward the text they enclose: opening and closing quotes are distinct shapes, and the apostrophe is a closing single quote. Straight quotes, the vertical marks a keyboard produces by default, are a typewriter artifact and have no place in a finished book. This is the single most visible line between a typeset book and a raw manuscript, and it is often the first thing a reader's eye catches as wrong even when they cannot name it.

Apostrophes deserve their own caution, because word processors frequently guess the direction wrong. A word that opens with an apostrophe, like 'twas or '90s, needs a closing-style curl, but autocorrect tends to insert an opening one, leaving the mark pointing the wrong way. It is a small thing that a trained eye spots instantly.

Italics for thought, and the double-hyphen tell

Interior monologue, a character's unspoken thought, is conventionally set in italics. This is a convention, not a law: plenty of fiction renders thought in plain roman type and lets the prose carry it, and that is a stylistic decision the author gets to make. What matters is that the treatment is consistent, so the reader learns to read italics as thought and is never confused about whose voice they are in.

Finally, the tell that ends this list where it began: a double hyphen standing in for an em dash. Two hyphens in a row are how a typewriter faked an em dash it did not have, and seeing them in a 2026 book signals immediately that the punctuation was never converted. It travels in the same company as straight quotes and mismatched ellipses. Clear those four out, and the page stops looking like a manuscript and starts looking like a book.

Or let the punctuation take care of itself.
