How to write a synopsis: the full-plot summary an agent requests
The synopsis an agent or contest asks for tells the whole plot, ending included: what it is, how it differs from a blurb or query, and how to write one.

Of every document traditional publishing may ask a novelist to prepare, the synopsis has the worst reputation: Jane Friedman calls it "probably the single most despised document you might be asked to prepare". The reason it is despised is the reason it exists. An agent or publisher asks for one, in Friedman's phrasing, because they want to see "from beginning to end, what happens in your story". It is the document that proves the whole book hangs together, and it cannot do that job while withholding anything.
Reedsy's guide compresses the definition into one line: the synopsis is a "1-2 page document that lays out your book's full narrative arc from opening to ending", carrying the reader through every major turn, from "the inciting incident to the climax and resolution", spoilers included. Agents and publishers, Reedsy adds, use it to quickly assess whether the manuscript is structurally sound and coherent. It is the only document in the package with that job, which separates it from its three cousins: the query letter is the one-page pitch, the blurb is reader-facing sales copy, and the logline is a single sentence.
Not a blurb, and not the query's pitch
The distinction from sales copy matters enough that Friedman opens her guide with it. "You're not writing a punchy piece for readers that builds excitement"; the synopsis is "an industry document that helps an agent or editor quickly assess your story's appeal". A blurb withholds the ending on purpose. A synopsis reveals it on purpose. Write one in the other's voice and both fail at their jobs.
One naming trap first. Some agents and editors use "synopsis" loosely for the short plot paragraphs inside the query, which Reedsy says "usually also contains a mini-synopsis of around 250 words". That mini-synopsis is a shorter, different document. When guidelines ask for "a synopsis", look for a requested length; the number tells you which of the two they mean. (The query letter glossary term keeps the vocabulary straight.)
Length and voice, as the sources state them
On length, Friedman's default: "a one- or two-page synopsis - about 500-1000 words, single spaced - and use that as your default, unless the submission guidelines ask for something longer". Her caveats: "most agents/editors will not be interested in a synopsis longer than a few pages", and "You'll find conflicting advice on this". Reedsy's worked example runs about 640 words and "fits comfortably within industry norms"; its practical suggestion is to keep a fuller and a tighter version. One to two pages is the default; the agent's guidelines are the only rule.
Voice is settled: "synopses should usually be written in third person, present tense (even if your novel is written in first person)", per Friedman, whatever person the novel itself uses. Nor is it the place for the novel's prose style; Friedman recalls the late agent Janet Reid telling writers that energy and vitality carry the document. Clean, lean, forward-moving sentences; no flourish.
Yes, it spoils everything
The question every first-time synopsis writer asks, whether the ending really goes in, has the same answer from both sources. Friedman: the synopsis "must convey a book's entire narrative arc", it shows "what happens and who changes", and "it has to reveal the ending". Reedsy's definition says the same thing with its "spoilers included". The spoiler is not a flaw in the document; it is the document.
This is because the synopsis is an assessment tool, not a teaser. Reading it, a professional can see whether "character actions and motivations are realistic and make sense", in Friedman's summary: whether the ending earns itself, whether the middle sags, whether the story is fresh. Her honest flip side: "some agents hate synopses and never read them". Write it anyway, to the guidelines, because you cannot know which kind of agent is opening your email.
Structure: beginning to end, or beat by beat
Friedman's method runs start to finish. Open with the protagonist, their situation and what drives them, then the inciting incident; from there, "each paragraph ideally moves the story forward (with events unfolding in exactly the same order as in the manuscript), with strong cause-effect storytelling", the key scenes included. By the final paragraphs the synopsis must show how the conflict resolves and how the protagonist has changed, inside and out.
Reedsy's method is the same journey mapped onto beats: its template walks the opening hook, inciting incident, rising action, midpoint, climax and denouement. Its caveat is worth keeping: "not every story will slot neatly into a textbook Three-Act structure"; what matters is that the synopsis "flows logically" and "each event grows naturally out of the last". Draft paragraph by paragraph in manuscript order or beat by beat through an outline; you arrive at the same document, chronological, causal, complete. That convergence is craft consensus, not a rule either source states.
What stays in
Friedman's rule of thumb settles most inclusion arguments: "If the ending wouldn't make sense without the character or plot point being mentioned, then it belongs in the synopsis". Everything else is a cutting candidate: subplots that never reach the ending, backstory, theme statements, dialogue. Reedsy's example synopsis drops every detail that does not "directly affect the story's final outcome".
Two of Friedman's cautions finish the job. Keep proper nouns to the minimum the ending needs; no cast lists, no subheadings. And avoid what she names synopsis speak, plot recounted without feeling: events alone read like a stage-direction log. Each movement should carry the protagonist's reaction and the decision it produces, and plainness is fine. "Often you have to tell", in her phrasing; the synopsis is the one craft document where telling is the assignment.
Where serial writers meet it
Serial platforms have no synopsis slot. A Royal Road or Wattpad listing runs on a blurb-shaped description and tags, and nothing in that machinery ever asks what happens at the end; the synopsis belongs to the traditional pipeline, where it rides alongside the query (publishing paths maps the routes). It re-enters a serial writer's life at two moments: querying agents with the finished work, and contests that ask for one with the sample pages.
The serial writer has one real advantage: the full plot already exists, ending included, so drafting the synopsis is compression of existing material, not invention. Write it third person, present tense, one to two pages, ending included, and send exactly what the guidelines asked for. When the pages behind it go out too, how to format a manuscript covers the conventions they travel in.

Craft claims above trace to these sources. Where a point is practitioner consensus rather than settled fact, the text says so.
