How to Write a Synopsis (Without Losing the Plot)

Most writers dread the synopsis more than the query letter. There's a reason for this: the synopsis requires you to compress your entire novel — all of its texture, voice, and emotional logic — into a flat procedural document. It feels like a betrayal of everything good about the book.

It doesn't have to be that bad.

What a synopsis is and isn't

A synopsis is a complete summary of your novel's plot, including the ending. Unlike a blurb or a query letter, a synopsis does not tease — it reveals. Agents and editors use the synopsis to assess whether your plot is structurally sound, whether your protagonist drives the story, and whether the ending earns what comes before it.

If an agent asks for a synopsis and you submit something that avoids the ending, you will likely receive a pass or a request for the actual synopsis.

Standard length

Most agents request a synopsis of 1–2 pages (single-spaced) or specify a word count. If no length is given, 500–800 words is a safe default. Some agents ask for longer synopses (up to 5 pages) — always follow the specific submission guidelines.

The structure that works

Act one (roughly 20–25% of the synopsis)

Establish your protagonist, their world, and their want or need. Then introduce the inciting incident that disrupts that world and forces the story into motion. This section should feel like the back cover copy — except you follow it through to the moment the protagonist commits to the story's central problem.

Act two (roughly 50–60%)

The complications, reversals, and escalations. What does your protagonist try? What goes wrong? What do they learn? What is the midpoint shift that changes the nature of the problem? This is where most synopses go wrong — they become a list of events. Focus on causality: this happened, which caused that, which forced the protagonist to do something else.

Act three (roughly 20–25%)

The climax and resolution. Be specific. Don't write "and in a dramatic confrontation, she finally faces her past." Write what actually happens. Name the choice the protagonist makes, its consequence, and where the story ends.

Voice in a synopsis

A synopsis is a functional document, but it doesn't have to be airless. Use your character's name rather than "the protagonist." Write in present tense. Let the genre's energy appear in your word choices. A thriller synopsis can be taut; a literary novel's synopsis can be elegiac. This is your chance to signal that the voice in the query is sustained through the entire book.

What to leave out

• Secondary plot threads unless they directly affect the main plot's resolution
• Backstory beyond what's essential to understanding character motivation
• Thematic statements ("this is a novel about grief and identity") — let the plot demonstrate it
• Scene-level description — the synopsis summarises what happens, not how a scene is written

Practical process

A useful shortcut: summarise each chapter in one sentence. Then group those sentences into three acts and cut the ones that don't carry causal weight. What remains is usually close to a working synopsis draft — which you then rewrite for flow and voice.
