How Many Words in a Novel? The Genre-by-Genre Answer Every Writer Needs

Somewhere around the third or fourth chapter of a first draft, almost every writer stops and asks the same question: how many words does this thing actually need to be? It is a fair question, and a surprisingly loaded one. Say the wrong number in a query letter and an agent might assume you do not know your genre. Write too few and a reader feels cheated. Write too many and a printer, a retailer, and eventually your own back start complaining.

So let us answer it properly. For most adult fiction, a finished novel sits somewhere between 70,000 and 100,000 words. That is the working range editors, agents and printers have quietly agreed on for decades, and it is the number to keep in your head if you are not sure where else to start. But “most adult fiction” is doing a lot of heavy lifting in that sentence, because a cosy mystery and a doorstopper fantasy series are not playing by the same rules at all. A cosy might wrap up nicely at 75,000 words. An epic fantasy can comfortably run past 120,000, and nobody blinks. For comparison, the entire Lord of the Rings trilogy comes in at around 455,000 words, which sounds enormous until you realise that is three books stitched into a single reading experience over ten years of writing. Nobody is expecting that from a debut.

At Dublin Publishing Press, word count is one of the first things we talk through with a new author, because it shapes everything downstream: how the book gets edited, how it gets priced to print, how it gets pitched to an agent, and how it sits next to other titles in its genre on a shelf. Get the number roughly right early, and the rest of the process gets a lot smoother. Get it badly wrong, and you are looking at a much heavier rewrite later. This guide walks through exactly where your manuscript should land, genre by genre, why that number exists in the first place, and what to do if your draft does not match it yet.

Most of the anxiety around this question does not actually come from writers not knowing roughly how long their book is. It comes from conflicting advice. One blog says 80,000; another says genre does not matter and you should “just write the story”; a writing forum insists agents auto-reject anything over 100,000 words on sight. All of that noise makes an already hard job harder. The truth sits somewhere calmer than any of it: there are real, genre-specific ranges, they are grounded in decades of publishing practice rather than superstition, and once you know them, the rest of your drafting decisions get a lot easier to make.

It does not matter whether you are drafting your very first manuscript, coming back to fiction after years away, or already deep into a self-publishing plan on your third book; the underlying numbers are the same, and knowing them changes how you plan the whole project, not just how you answer a query form. Someone drafting their debut needs this information to avoid a first-pass rejection. Someone self-publishing needs it to price a paperback sensibly. Someone querying a second book needs it to know how much room they have actually earned to push past convention. Different reasons, same starting point.

Word Count by Genre: The Numbers You Actually Need

This is the part most writers bookmark, so let us get straight into it. Below is a genre breakdown covering the ranges publishers and agents typically expect, alongside how the median word count for each genre has actually moved between 2023 and 2024, based on recent industry research into published fiction.

A few of those numbers deserve a closer look, because the ranges only tell half the story.

Fantasy and science fiction both carry room to breathe, and for good reason: world-building takes pages. But there is a real difference between a sprawling space opera and a tight, near-future thriller wearing a sci-fi coat. If your story leans closer to the second kind, do not force it up to 120,000 words just because “that is what sci-fi does”. A grounded, plot-driven sci-fi novel can land at 85,000 words and feel completely finished.

Romance is the genre with the widest personality. A contemporary romance tends to sit on the leaner end, closer to 70,000 to 90,000 words, built for pace and payoff. A historical romance, with its extra layer of setting and period detail, often creeps up towards 100,000. Neither is wrong; they are just answering to different reader expectations.

Middle grade is the one category where shorter genuinely means better. Young readers want momentum, not density, and a middle grade manuscript that balloons past 55,000 words often has more to do with the author’s habits than the story’s needs. If you are writing for that younger audience specifically, it is also worth having a conversation early about pacing and structure with people who work in that space regularly. Our team handles a fair amount of children’s book publishing work, and it is one of the categories where word count discipline pays off fastest.

Mystery and thriller sit in a comfortable, well-worn groove, generally 80,000 to 100,000 words, and that consistency is part of why the genre reads so predictably satisfying. Readers know roughly how much runway they have got before the resolution, and pacing gets built around that expectation. Literary fiction has more room to move, 80,000 to 100,000 words as a rule, though the genre has always tolerated outliers on both ends more than commercial fiction does, since the writing itself is doing a different kind of work than plot momentum.

Young adult fiction runs noticeably leaner than most people assume, typically 55,000 to 80,000 words. Teen readers want pace, and a YA manuscript that drifts towards adult-fiction length usually has adult-fiction padding hiding somewhere inside it. Historical fiction tends to sit on the longer side, 90,000 to 120,000 words, mostly because there is a second job happening alongside the story itself: establishing a time and place convincingly without turning the book into a history lecture. And memoir is genuinely the hardest of the eleven to pin down, roughly 60,000 to 90,000 words in practice, because a memoir’s length depends entirely on how much life the story actually needs to cover rather than any genre convention.

Horror is the genre that moved the most between 2023 and 2024, climbing nearly 12,000 words in its median length. That shift lines up with a run of upmarket horror titles that blur into literary fiction, and readers responding well to that crossover. Meanwhile, action and adventure fiction went the opposite direction, dropping by roughly 16,000 words as shorter, faster-paced serialised fiction ate into that space. Word count is not fixed. It moves with what readers are actually buying, which is exactly why treating any number as gospel is a mistake, and why it is worth checking current numbers rather than working off whatever you were told five years ago.

Has the Average Novel Always Been This Long?

Not even close, actually, and it is worth knowing why before you assume the numbers above are some kind of fixed law of nature. Plenty of novels considered classics today would raise eyebrows by current standards; some run remarkably short by today’s genre expectations, others were published in serialised instalments that only became a single “novel” once they were bound together afterwards. The idea of a tidy, standardised word count is much more recent than the novel itself, and it is tied directly to the mechanics of modern publishing: print costs, standard trim sizes, and the practical limits of what a printing press and a bindery can produce economically at scale.

What has changed more recently is the influence of digital-first reading. Ebooks do not have a physical page count that affects shipping weight or shelf space, so genres read primarily on digital devices have had more room to drift, in both directions. Some categories have crept longer because there is no printing cost punishing length. Others, especially fiction built for quick digital consumption, have trended shorter because reader attention now competes with a phone in the other hand. The genre movements in the table above — horror climbing, action and adventure shrinking — are part of that same ongoing shift rather than a one-off blip. The average novel word count is not handed down from anywhere. It is simply where enough writers, readers and publishers have converged, for now, and it will keep moving as reading habits do.

Why Word Count Actually Matters (It Is Not Just a Rule for Rules’ Sake)

Here is the thing nobody explains properly when they hand a new writer a word count chart: these are not arbitrary numbers someone in publishing made up to gatekeep newcomers. They come from real, practical pressures that hit a book at every stage of its life, from the moment an editor opens the file to the moment a reader picks it off a shelf.

Start with print costs. A longer book uses more paper, costs more to produce, and needs a higher retail price to make the same margin. For a debut author with no sales history behind them, a 150,000-word fantasy manuscript is a genuinely riskier bet for a publisher than a 100,000-word one, purely on the economics. This is why editors so often ask first-time authors to trim before submission, not because they are being precious about round numbers. It is a straightforwardly commercial decision, and understanding it takes a lot of the sting out of a trim request when it lands in your inbox. If your fantasy draft is creeping past 120,000 words, it is usually worth thinking about whether it is actually two books rather than one oversized one; splitting a story cleanly is almost always kinder to the reader than asking them to carry one enormous volume around. We handle a lot of book printing for authors going the traditional or hybrid route, and length is genuinely the first thing that affects your unit cost, well before cover stock or trim size even come into the conversation.

Then there is the practical reality of how agents read. They are getting through hundreds of queries a month, and a manuscript that is wildly outside the expected range for its genre reads as a warning sign before anyone has even opened the first page. It does not necessarily mean the writing is bad. It usually means either the author does not know their genre’s conventions yet, or the manuscript needs an editing pass. Literary agents have said as much publicly: once a word count starts climbing well past what is typical, their interest in the concept can start to wane before they have read a single line, purely because a longer manuscript signals more risk and more work. Agents who are otherwise perfectly open to unconventional length in speculative genres, where a sprawling story sometimes earns its size, still tend to draw a firmer line with literary or commercial fiction, where an oversized debut usually reads as an editing problem rather than ambition.

Retail shelving plays its part too. A physical bookshop has finite space, and a 600-page debut takes up the same shelf real estate as two 300-page books from established names, which makes a bookseller’s decision about what to stock a fairly straightforward numbers game before it is ever a question of quality. Readers have their own quiet expectations baked in as well, usually without even realising it. Someone picking up a romance wants a satisfying arc delivered in roughly 70,000 to 90,000 words, not 150,000, and a book that runs wildly against genre norms can feel like it has broken an unspoken promise, even if the writing itself is strong. Word count, in that sense, is as much a marketing signal and a promise to the reader as it is a production detail, and it interacts directly with how a book gets categorised and positioned once it is live. That positioning work is a big part of what we do through book marketing at Dublin Publishing Press, because getting a book in front of the right readers depends on setting the right expectations from the very first page.

Finally, there is the gap between debut and established authors. A writer with a strong sales track record can sometimes get away with a longer, more ambitious book, because a publisher has evidence the audience will follow them anywhere; a bestselling series author who wants to write a 160,000-word instalment is not taking the same gamble a first-timer would with the same page count. A debut does not have that safety net yet. If this is your first novel, aim for the middle of your genre’s accepted range rather than either edge. A 90,000-word thriller is a much safer pitch than a 120,000-word one when nobody has heard your name before, simply because there is no existing readership to absorb the risk if it does not land.

Word Count vs. Page Count: What Agents Actually Mean When They Ask

Query forms do not always ask for a word count. Sometimes they ask for a page count instead, which trips up a lot of first-time authors who have only ever thought in words, especially since almost nobody actually counts pages by hand any more, and a manuscript formatted casually can throw the estimate off by tens of thousands of words without the author noticing.

The convention exists for a genuinely practical reason. Before word processors could count words instantly, page count was the only reliable proxy anyone had, and the industry simply never fully let go of the habit even once the technology caught up. That is why the two systems still coexist today, and why it is worth being fluent in both rather than assuming everyone means the same thing when they ask “how long is it”.

The industry-standard manuscript format is fairly rigid, and it exists specifically so that word count and page count can be converted between each other reliably:

• Font — 12-point Times New Roman, or a similar serif font
• Spacing — double-spaced
• Margins — one inch on all sides
• Alignment — left-aligned, never justified
• Indentation — first line of each paragraph indented by half an inch

Format your manuscript that way, and you will land at roughly 250 to 300 words per page. To go from word count to page count, divide your total by 250 for a conservative estimate or 300 for a more generous one. An 80,000-word manuscript, for instance, works out to somewhere between 267 and 320 double-spaced pages.

Do not try to estimate this by counting words per line and multiplying, the way older writing guides sometimes suggest. That method is genuinely outdated now — use your word processor’s actual word count tool, every time.

If you are not confident your manuscript is formatted to the standard in the first place, it is a quick, worthwhile fix. Formatting is a small but easy thing to get wrong, and it is one of the more common jobs we take on through book formatting, because a manuscript that looks right on the page reads as more professional before an agent has even reached the story itself.

Chapter Length: The Pacing Question Nobody Talks About Enough

Chapter length gets far less attention than overall word count, but it shapes how a book actually feels to read, sometimes more than the total length does. Two novels can sit at exactly 90,000 words and read completely differently depending on how that word count is broken up. There is no universal rule here, just genre-driven convention:

• Thriller — roughly 1,500 to 3,000 words a chapter, because short chapters create momentum and make a book feel unputdownable.
• Literary fiction — often 3,000 to 5,000 words, giving a scene room to breathe and a reader time to sit with a character’s interior life.
• Romance — usually 2,000 to 4,000 words, balancing scene and emotional follow-through.
• Fantasy — 2,500 to 5,000 words, because world-building and multiple plot threads need the space.

The instinct to treat chapter length as a fixed quota is one worth resisting. Let pacing decide where a chapter ends, not a word counter. A thriller with consistently short, punchy chapters will read faster and feel tighter than the same story chopped up arbitrarily every 4,000 words regardless of where the tension actually breaks, and a bit of natural variation from chapter to chapter is normal and usually a good sign rather than something to smooth over in editing.

How to Set and Track Your Own Word Count Goal

Once you know roughly where your genre lands, the next step is turning that number into something you can actually work towards day by day. It breaks down into four straightforward steps.

First, choose your target word count. Use the genre table above to identify your ideal range, and if this is your debut, aim for the middle of the range rather than either edge; it is the safer, more marketable choice. Write down an actual number here, not a vague range. “Somewhere around 90,000” is not a target you can build a schedule around; “92,000” is.

Second, calculate your daily writing goal. The formula is simple: divide your target word count by the number of days you realistically have to write. Eighty thousand words over a hundred writing days comes out to 800 words a day, which is a manageable, sustainable pace for most people juggling a full life alongside a manuscript. Be honest about your actual available days here, including the ones you will lose to work, family and the general unpredictability of life, rather than the idealised version of your schedule.

Third, track your progress somehow, even if it is just a spreadsheet. What matters more than the tool is the habit of checking in regularly, because it catches drift early, long before a missed week turns into a missed month.

Fourth, adjust as you go. If you fall behind, do not panic and do not binge-write to catch up in one weekend; just recalculate your daily goal based on the days you have left. If you are consistently running ahead of pace, it is worth asking whether your target was actually too conservative, or whether your pacing has sped up in a way the story does not need.

Not everyone wants to do this drafting stage entirely alone, and there is no shame in that. Plenty of authors come to us with a fully formed idea, an outline, even a partial draft, and want a professional hand getting the rest of the words onto the page in their voice. That is exactly what our ghostwriting service at Dublin Publishing Press exists for, whether you need the whole manuscript built out or just help pushing through a stuck middle section.

What to Do If Your Word Count Is Too High or Too Low

Almost no first draft lands exactly on target, and that is completely normal; treat it as a data point about where your revision needs to focus, not as a verdict on the story itself. What matters is knowing how to fix it without damaging the story underneath.

If your manuscript is running long, start by cutting filler: any scene that does not move the plot forward or reveal something new about a character has to earn its place, or go. Tighten the prose itself, watching for wordy sentences and passive constructions that quietly inflate a word count without adding anything. If you are writing fantasy and you have genuinely broken past 120,000 words, seriously consider whether you are looking at two books rather than one overlong one. And resist the urge to pad a manuscript that is under target just to hit a round number; agents and editors can spot filler from a mile away, and it is far better to deepen a subplot or strengthen a character arc than to add empty scenes. If your draft needs a proper professional pass to find where the fat actually is, that is precisely the kind of work we do through book editing, and an experienced editor will usually spot the difference between “needs cutting” and “needs restructuring” faster than you can on your own manuscript.

If your manuscript is running short, the fix usually is not more description; it is more depth. Add scenes that show real internal change in your characters rather than just telling readers about it. Give your secondary characters more page time and let their subplots breathe. Expand the sensory detail in your world-building, if that is relevant to your genre. And check your genre expectations honestly. A 50,000-word fantasy is very likely too short for what readers expect from the genre; a 50,000-word cosy mystery might be exactly right, since the genre’s whole appeal is a brisk, tidy read. A useful rule of thumb once the first draft is finished either way: a common editing pass goal is cutting around ten percent of a manuscript’s length, tightening prose and trimming anything that is not pulling its weight, then reassessing from there rather than trying to hit a perfect number in one single pass.

Self-Publishing vs. Traditional Publishing: Does Word Count Flexibility Change?

Word count rules apply differently depending on which publishing path you are on, and it is worth understanding the difference before you get too attached to a specific number.

In traditional publishing, agents and imprints hold the line fairly firmly, because they are the ones carrying the financial risk if a book underperforms. A debut author who strays too far outside the accepted range for their genre risks an automatic pass before an agent has even read the sample pages, which is a genuinely frustrating way to lose a chance, given how much work goes into a query in the first place. When you do query, always round your word count to the nearest thousand rather than giving an exact figure. “Approximately 87,000 words” reads as confident and professional. An oddly specific number like “87,342 words” reads as slightly anxious, and a page count instead of a word count should only come up if it is specifically requested.

Self-publishing loosens that grip considerably, but it does not remove the pressure entirely. If you are going the self-publishing route through something like Amazon KDP, you have far more freedom to write the book your story actually needs rather than the book a query market expects. That said, print costs and reader expectations have not disappeared just because there is no gatekeeper. A very short novel can genuinely struggle to justify a full retail price in paperback, while an extremely long one eats into your own royalties through higher printing costs per copy. We support authors through the full Amazon KDP publishing process here, and word count is one of the first practical conversations that comes up, because it affects your pricing strategy from day one.

There is also a growing middle path worth mentioning: hybrid publishing, where an author pays for professional production and editorial support but keeps far more creative control than a traditional deal usually allows. Word count flexibility here sits somewhere between the two extremes. You are not fighting an agent’s inbox for attention, so the pressure to hit an exact genre target eases considerably, but the production realities of print cost and reader expectation are still very much in play, so it is rarely a licence to ignore genre norms altogether.

Cross-Genre and Emerging Word Counts: Romantasy, Cli-Fi and Uplit

The genres above cover most of what is being written, but hybrid and emerging categories are growing fast, and their word count conventions are still settling.

Romantasy, blending romance’s pace with fantasy’s scale, generally lands between 80,000 and 100,000 words, leaning towards the lower end if the romance plot is doing most of the heavy lifting and the fantasy elements are more backdrop than engine. Climate fiction, often shortened to cli-fi, tends to follow whichever parent genre it is closer to; a literary climate novel usually sits at 70,000 to 90,000 words, while a more speculative one can stretch to 100,000. Uplit, the newer category of hopeful, warm-hearted fiction that sits between commercial and literary work, generally targets 70,000 to 90,000 words, similar to typical book club fiction. Dystopian romance leans on both its parent genres at once, usually landing at 80,000 to 100,000 words, tightening closer to 80,000 when the romance is the clear centre of the story.

None of these numbers are hard data the way the established genre figures are; they are informed estimates based on how the parent genres behave, because these categories are still evolving and publishers have not fully standardised around them yet. If you are writing in one of these spaces, the safest approach is to identify which parent genre dominates your comp titles and lean towards that benchmark when you query, rather than inventing your own rule.

This is also usually where a manuscript most benefits from an outside read before it goes anywhere near a query inbox. Cross-genre books are genuinely harder to position, because the writer often cannot see clearly which side the story leans towards after months spent inside it, and that is exactly the kind of blind spot a fresh, experienced set of eyes tends to catch fastest.

A Quick Decision Path, If You Are Still Not Sure

If you have read this far and you are still not certain what your number should be, run through this in order:

1. What genre are you writing? Find the closest match in the table above; if nothing fits exactly, pick the genre your story reads most like on the page, not the one you would love it to be marketed as.
2. Is this your debut? If yes, aim for the middle of that genre’s range. If you have published before, you have got a little more room to move.
3. Are you writing across genres? If so, work out which parent genre dominates your comp titles and lean towards that number rather than averaging the two.
4. What is your actual target number? Write it down specifically, not as a range.
5. How many writing days do you realistically have? Divide your target by that number to get your daily goal.
6. How will you track it? Pick something you will actually keep up with, whether that is a spreadsheet, an app, or a plain notebook.

Six questions, six honest answers, and you will have a number worth building a schedule around instead of a guess borrowed from someone else’s genre.

Getting from Manuscript to Finished Book

Hitting the right word count is really just the first practical milestone in a much longer process, and it is worth zooming out to see where it fits, especially if this is your first book and the whole path still feels a bit abstract.

Once your draft is at a length that matches your genre, the next stage is usually a structural or line edit, where a second pair of eyes catches things a writer simply cannot see in their own manuscript after months or years inside it. From there, the decisions shift towards things that have nothing to do with word count at all: what the cover looks like, how the book will be positioned to readers, whether you want it in print, as an ebook, or read aloud entirely. A striking cover matters more than most first-time authors expect, and it is one of the areas where a professional eye makes a visible difference; that is the kind of work we take on through book cover design. Plenty of authors also want a proper home online for their book and their author identity beyond a single retail listing, which is where author website design comes in, particularly once you are building a readership across more than one title. And increasingly, readers want to listen rather than read, which is why audiobook production has become such a natural next step for finished manuscripts rather than an afterthought tacked on at the end.

Word count is the number that gets a manuscript taken seriously in the first place. Everything after it — the editing, the cover, the format, the way readers actually find the book — is about making sure the finished product reaches the people it was written for. Get the number right early, and every step after it gets just that bit easier.
