Book Blurb: How to Write One, With Examples and a Template

A book blurb is the short piece of sales copy on the back cover, inside flap or retail page of a book: it introduces the main character and the situation, sets up the conflict and the stakes, and stops before the ending so the reader has to open the book to find out. On Amazon and other stores the same text is usually called the book description.

Most fiction blurbs follow one shape: a hook, a character, the event that disrupts their life, what stands in their way, what they stand to lose, and a closing line that leaves the question open. This page covers that shape, how long a blurb should be on a back cover and online, a fill-in template, original examples by genre, and where the word came from.

What Is a Book Blurb?

Dictionaries agree on the core meaning. Cambridge defines a blurb as "a short description of a book, film, etc., written by the people who have produced it, and intended to make people want to buy it or see it". Oxford Learner's adds that it "is intended to attract your attention and make you want to buy it".

Two things in publishing get called a blurb:

• The description. The paragraphs on the back cover of a paperback, the inside flap of a hardback jacket, or the description box on a retail page. This is what an author is usually asked to write, and what this page is about.
• The endorsement. A line of praise from another author or a reviewer ("Gripping from the first page"). In publishing, especially in the US, the word often means this. Literary Hub's history of the word notes that the term "has of course since expanded to include endorsements from other writers".

A back cover often carries both: endorsements at the top, the description below.

Where Does the Word "Blurb" Come From?

The American humorist Gelett Burgess coined it. Copies of his book Are You a Bromide? were given out at an American Booksellers Association dinner, with a joke dust jacket showing a young woman he called Miss Belinda Blurb. The jacket read: "YES, this is a 'BLURB'! All the Other Publishers commit them. Why Shouldn't We?" It also carried the caption "MISS BELINDA BLURB IN THE ACT OF BLURBING".

The publisher, B. W. Huebsch, later wrote that Burgess drew a comic bookplate and "a special jacket which he devised", and that "thus the term supplied a real need and became a fixture in our language." (Huebsch's account, from The Colophon, spells her "Miss Blinda Blurb".)

Burgess then put the word in his own joke dictionary, Burgess Unabridged (1914):

"Blurb, n. 1. A flamboyant advertisement; an inspired testimonial. 2. Fulsome praise; a sound like a publisher."

He described the blurb on "the 'jacket' of the 'latest' fiction" as "abounding in agile adjectives and adverbs, attesting that this book is the 'sensation of the year'". So the word began as mockery of exactly the kind of overheated copy that still makes a weak blurb.

A date that is often stated too firmly. The coinage is usually given as 1907, the year of the booksellers' dinner. In 2016 the lexicographer Fred Shapiro reported on the American Dialect Society list that the rare-book dealer Peter Harrington held a copy of the 1906 first edition whose original jacket already used the word. Either way, the jacket came first and the dictionary entry second, seven or eight years later.

Blurb vs Synopsis vs Query Pitch vs Tagline

These four are often confused, and each has its own job.

	Who reads it	Length	Reveals the ending?
Blurb	Readers deciding whether to buy	Usually 100 to 200 words	No
Synopsis	Agents and editors	Usually 250 to 1,500 words, often about a page	Yes, always
Query pitch	Agents	One or two lines	No
Tagline	Readers, at a glance	One short line, often on the front cover	No

The clearest line runs between the blurb and the synopsis. A one-page synopsis tells the whole story plainly, ending included, so an agent can judge its shape. A blurb sells the opening situation and stops. A query letter usually contains a blurb-style paragraph, which is why the same draft often does double duty.

How Do You Write a Book Blurb?

Work through these in order. The first draft will be too long; that is normal.

1. Find the hook. The single most surprising fact about the setup, in one sentence. Not the theme ("a novel about grief") but the situation ("Her husband has been dead for a year, and this morning he sent her a text").
2. Introduce one character. Name the protagonist and give them one defining detail: a job, a flaw, a want. Two names is fine for a romance; more than three and the reader stops tracking.
3. Show the disruption. The inciting incident is usually the heart of the blurb. "But when..." is a cliché for a reason: it works.
4. Name the obstacle. Who or what stands in the way. One complication is enough to show it will not be easy.
5. State the stakes. What happens if they fail. Make it concrete and personal, not "everything will change".
6. End on the open question. A choice, a dilemma or a line that tilts forward. Many blurbs end on a literal question; a statement that implies one often reads better.
7. Write in the book's voice. A comic novel gets a funny blurb. A dark thriller gets short, hard sentences. The blurb is the first sample of your prose most readers see.
8. Cut. Remove subplots, secondary characters, backstory and every adjective that is doing a job a verb could do.

Stop at the point where the main conflict is locked in, often around the end of the first act. Anything after that belongs in the synopsis, not on the cover.

How Long Should a Book Blurb Be?

No publisher or retailer sets a word count for a back-cover blurb. The practical limit is the space on the cover, and the range most guides give is about 100 to 200 words. Shorter is common for thrillers and commercial fiction; non-fiction and epic fantasy tend to run longer.

Online the rules are stricter and written down. Amazon KDP's help page Write a Book Description says: "Note that we have a limit of 4000 characters for the description," and "the text editor will count all characters used, including any HTML tags." That is far more room than a good blurb needs. The opening lines are what a browsing reader sees first, so the hook has to land there.

The same KDP page lists book description restrictions. Among them:

• "Reviews, quotes, or testimonials"
• "Spoiler information for Books, Music, Video, or DVD (BMVD) listings"
• "Time-sensitive information"
• "Any keywords or book tags phrases"

So the endorsement blurbs on your back cover do not belong in the KDP description field, and neither does the ending.

How Is a Back Cover Blurb Different From an Amazon Book Description?

The core paragraphs can be identical. The frame around them differs.

	Back cover blurb	Amazon book description
Length	Limited by the cover, usually 100 to 200 words	Up to 4,000 characters, HTML included
Endorsement quotes	Common, often at the top	Not allowed in the KDP description field
Formatting	Set by the cover designer	Basic HTML: bold, italics, lists, small headings
First thing seen	The whole thing at once	The opening lines, near the top of the page
Can change after publication	Only with a new printing	Yes, from Edit Details on your Bookshelf

Book Blurb Template

Fill in the brackets, then rewrite until it no longer reads like a template.

[Hook: the most surprising fact of the setup, in one sentence.]

[Name] is a [role or defining trait] who [what they want, or the life they have].

But when [inciting incident], [name] must [goal].

Standing in the way is [antagonist or obstacle], and [one complication].

If [name] fails, [concrete, personal stakes].

[Closing line: the choice, dilemma or question the book will answer.]

For a romance, run the middle lines twice, once for each lead, then add the barrier between them. For non-fiction, swap the character for the reader: the problem they have, what the book promises, and why this author can deliver it.

Book Blurb Examples

All four examples below were written for this page. None is a real book.

Thriller (89 words)

Nobody audits a dead man's accounts. Nell Okafor does it anyway.

A forensic accountant with a gift for numbers and none for people, Nell is hired to close the books on a Glasgow shipping firm after its founder falls from his office window. The figures are clean. Too clean.

Then the firm's lawyer asks her to sign them off by Friday, and someone starts following her home.

Nell has found eleven million pounds that should not exist. Now she has five days to find out who it belongs to.

Romance (99 words)

Ada Finch has one rule for her bakery: no investors. Theo Marsh has one job: buy it.

Ada has kept her late grandmother's shop open for three years on flour, stubbornness and very little sleep. Theo is the developer's son sent to make her an offer she can't refuse, and he expects to be back in London by the weekend.

He does not expect to start helping with the four a.m. bake.

When the offer finally comes, Ada will have to choose between the shop that is all she has left and the man who came to take it.

Fantasy (98 words)

In the city of Vell, every lie leaves a mark on the liar's skin. Corin has none.

That should make him the most trusted clerk in the Counting House. Instead it makes him a question nobody wants asked, because the only people born unmarked are the ones who cannot lie at all, and the Guild has spent a century making sure there are none left.

When a dying councillor tells Corin a truth that could bring the Guild down, he becomes the one witness they cannot bribe.

And the only way to survive is to learn to lie.

Cosy mystery (85 words)

The vicar's prize marrow has been poisoned, and by Sunday the vicar has too.

Retired schoolteacher Joan Pell came to Little Hawden for the quiet, the allotments and the absence of other people's children. Now the village flower show is short one judge, and the police have arrested the one man Joan is sure is innocent: her new neighbour.

Six rivals, one weedkiller and a parish newsletter full of secrets.

Joan has a week to find the killer before the show goes on without her.

How Do Blurbs Differ by Genre?

Genre	What the blurb leads with	What readers look for
Thriller	The threat and the clock	Short sentences, a deadline, a professional protagonist
Romance	Both leads and what keeps them apart	The trope, the setting and a hint of the heat level
Fantasy	One striking rule of the world	A single world detail, not a glossary of names
Mystery	The crime and the sleuth	Who died, who is suspected, why this detective
Literary fiction	Voice and situation	A precise, unusual premise in concrete terms
Non-fiction	The reader's problem	The promise, who it is for and the author's credentials

A blurb is also a genre signal. A romance novel blurb that reads like a thriller will find the wrong readers, and they will say so in the reviews.

A Worked Example: From Synopsis to Blurb

An original story, The Salt Ledger. Here is the first draft, written the way most first drafts are, as a summary:

Maren Holt is a bookkeeper in the fishing town of Skelby. When three boats are lost in a storm, she notices that the insurance claims don't match the catch records. She investigates and finds out that the harbourmaster, her uncle, sank the boats for the insurance money. In the end she reports him to the police and leaves Skelby.

It is accurate and it is dead. It names the culprit, gives away the ending and has no hook. Rebuilt with the template:

Three boats went down in the March storm. Only Maren Holt has noticed that their catch was sold the week after.

Maren keeps the books for half of Skelby's fishing fleet. She knows every debt in the harbour, and who owes it. So when the insurance money arrives before the bodies do, she starts checking the figures nobody else reads.

The numbers lead to the harbour office, where her uncle has kept the keys for thirty years.

The truth would sink the town's first good year in a decade. Silence means three widows never learn why their husbands drowned.

How much is a ledger worth, when every name in it is family?

What changed:

• Hook first. The strangest fact (the catch sold after the boats sank) opens the blurb.
• The culprit is pointed at, not named. "Where her uncle has kept the keys" lets the reader suspect without being told.
• The ending is gone. Whether she reports him is the question the book answers, so the blurb asks it.
• The stakes are a choice. Both options cost Maren something, which is what makes the reader want to know which she picks.

How Do You Write a Book Blurb in Deckle?

Deckle is a novel-writing app for Windows, macOS and Linux, and the blurb works best kept inside the project, beside the manuscript, where you can draft it against the actual opening chapters. Its Research area holds documents that are part of the project but never part of the book.

1. In the Binder, click Add to Research (the + beside Research) and choose New Note.
2. Right-click the new note, choose Rename and call it "Blurb".
3. Click the Split Editor button and open your first chapter in the other pane, so you can borrow the book's own voice and details while you write.
4. Draft the blurb. The Inspector shows the note's Words and Chars as you type; select one paragraph and they read as a share of the total ("42 of 160"), so you can see which paragraph is carrying too much.
5. Before each big rewrite, open the Inspector's Versions tab, click New Snapshot (the +), name it ("Back cover, 160 words"), and save. Keep a back-cover version and a longer online version side by side as separate snapshots, and Restore either when you need it.
6. When it is final, copy the text into your retailer's description field, such as Description on KDP's Edit Details page.

Because the note sits in Research, it never goes into the compiled book (EPUB, PDF or DOCX) and never counts toward the book's word count. The same note is a natural home for your pitch line, comp titles and synopsis drafts, all in one place. For more on how Research keeps material out of the book, see the Research folder, and for working with snapshots, taking a snapshot before a big revision.

Common Mistakes

• Summarising the plot. A blurb that walks through events in order is a synopsis. Stop at the point where the main conflict is set.
• Revealing the ending. It loses the sale and, on KDP, breaks the rule against spoilers in the description.
• Too many names. One protagonist, one antagonist, perhaps one more. Every extra name costs the reader effort.
• Theme instead of situation. "A story about love and loss" describes thousands of books. "A widow finds her husband's second family two streets away" describes one.
• Burgess's adjectives. "Gripping", "unforgettable", "a sensation": the exact copy he mocked in 1914. Let the situation do the work.
• Putting review quotes in the KDP description. Keep them for the cover, not that field.
• Writing it last, in a hurry. The blurb sells the book. Draft it early, revise it alongside the manuscript and test it on readers who haven't read the book.
