Almost every new novelist asks how long a novel should be, usually hoping for one number. The honest answer is that word count is a convention shaped by genre, audience and format, not a law of writing. Readers of a genre come to expect a certain kind of experience, and length is part of that expectation, but it is a guide rather than a gate.
This guide sets out the typical ranges by genre, why they exist, and how to decide whether your manuscript needs cutting or has more room to grow.
Why does word count matter at all?
Word count affects printing costs, shelf expectations, reader time investment and, for some routes, whether agents and publishers will consider a manuscript at all. None of that makes a specific number correct for your book; it just explains why conventions exist and why it is worth knowing them before you commit to a very unusual length.
What is typical for commercial fiction?
General commercial and upmarket fiction most often lands somewhere around 80,000–100,000 words. This range gives enough space for a full plot and character arc without asking too much of a reader picking the book up for entertainment.
How does typical length differ by genre?
| Genre | Typical range | Notes |
|---|---|---|
| Thriller / crime | 70,000–90,000 | Pacing usually favours leaner manuscripts. |
| Romance | 70,000–90,000 | Category romance often sits at the shorter end; single-title romance can run longer. |
| Fantasy | 90,000–120,000+ | World-building and multiple plot threads often need more space; debut fantasy is frequently advised to stay tighter than established series entries. |
| Science fiction | 90,000–110,000 | Similar drivers to fantasy, slightly more variable. |
| Literary fiction | 70,000–100,000 | Wider tolerance for shorter or more unusual lengths. |
| Young Adult | 55,000–90,000 | Varies by subgenre; fantasy YA often runs longer than contemporary YA. |
These are broad, typical figures rather than thresholds. For example, plenty of well-regarded novels sit outside every range in this table.
Does word count matter more for a debut novel?
Somewhat. Agents and publishers weighing a first novel often use word count as a rough proxy for control and editability, since a very long debut can suggest the story has not yet been tightened. This is a practical consideration for that route rather than a judgement on the writing itself, and it matters much less if you are self-publishing.
When does a long manuscript become harder to publish?
Once a manuscript runs well beyond genre expectations, three practical issues tend to appear: agents and publishers may see it as a bigger risk to acquire and edit, print costs rise noticeably in self-publishing, and readers may find the pacing sags in the middle. None of this means a long book is automatically wrong, only that length adds friction worth being aware of.
When does a short manuscript feel underdeveloped?
A manuscript can sit inside a "normal" word count and still feel thin if subplots are missing, characters are underexplored or the ending arrives before the stakes have been earned. Word count alone will not tell you this; it usually shows up as pacing that feels rushed or a resolution that lands too easily. How Do I Know If My Plot Is Strong Enough? looks at this from the plot side.
Does self-publishing change the rules on length?
Yes, to a degree. Without an agent or acquiring editor weighing risk against a category norm, you have more room to let a book run its natural length. Print costs still rise with page count under print-on-demand, and reader expectations within a genre still apply, but the gatekeeping pressure around word count is lighter.
How do I decide whether to cut or expand?
- 1
Check against genre, not a universal number
Compare your manuscript to recently published books in your specific genre and subgenre, not fiction in general.
- 2
Look for scenes that repeat a purpose
If two scenes do the same emotional or plot work, one is usually a cutting candidate.
- 3
Look for underdeveloped threads
A subplot introduced and dropped, or a character arc without a clear turn, often signals room to expand rather than a book that is simply short.
- 4
Read for pacing, not just count
A slow middle section is a pacing problem to solve on its own terms, not something word count alone will fix.
Common mistakes
- Treating a genre range as a hard limit. Ranges describe what is typical, not what is permitted. Plenty of successful novels sit outside them.
- Padding a short manuscript with filler scenes. Adding words without adding story usually makes pacing worse, not better.
- Ignoring genre entirely and comparing to fiction in general. A thriller and an epic fantasy have very different reader expectations for length.
- Assuming a long debut is automatically unpublishable. It is a harder sell through some routes, not an impossibility, and self-publishing removes much of that pressure.
Frequently asked questions
Is there an ideal word count for a first novel?
No single ideal exists, but many debut commercial novels land in the 80,000–100,000 word range because it balances story space with editability. Genre still matters more than the fact of being a debut.
Is 150,000 words too long for a novel?
It is long for most genres and would face closer scrutiny from agents and publishers, but it is not automatically unpublishable, particularly in epic fantasy or if you are self-publishing.
Should I worry about word count while drafting?
Generally not in the first draft. It is more useful during revision, once you can see the actual shape and pacing of the story.
Does word count include or exclude front and back matter?
Word count conventions usually refer to the manuscript body, not the title page, acknowledgements or other front and back matter.
