How Many Words Do I Need In My Book?

Posted on 12th May 2025

It’s one of the most common questions I’m asked by aspiring authors-usually just after they’ve written either 3,000 words and called it a novel, or 150,000 and referred to it as ‘…a short story that got slightly out of hand’.

It’s a fair question, but the answer isn’t as clear-cut as people might hope.

There’s no fixed rule.

That said, there are expectations — shaped by publishers, genres, and the attention span of readers (many of whom now prefer books that don’t double as doorstops).

So, here’s a rough guide:

Standard Novel: 70,000–100,000 words

Crime/Thriller: 80,000–95,000

Fantasy/Sci-Fi: 90,000–120,000+

Literary Fiction: 75,000–100,000

Memoir: 70,000–90,000

Self-help/Business: 40,000–60,000

Children’s Fiction (8-12 years): 30,000–50,000

Young Adult: 60,000–80,000

Picture books: Under 1,000 (and every word has to earn its place)

Of course, great books break the mould.

But these ranges are useful if you're aiming to publish — especially if you're submitting to an agent or editor.

Which brings me to the next bit: how to send your manuscript for editing or review.

My advice?

Keep it simple:

Double-spaced, in a readable font. My preference, font wise, is Calibri, size 10.

Clearly marked chapters or sections

A brief note explaining what you’ve written, what you're hoping to achieve, and what kind of feedback or help you’re looking for

Typos?

Don’t panic. It’s a draft — they’re called ‘drafts’ for a reason and I expect rough edges.

Even the site of the most beautiful house and accompanying richly manicured gardens was a field of mud to start with.

But do give it a quick proofread.

There’s a world of difference between a sentence that’s ‘publicly admired’ and one that’s ‘pubicly admired.’

Above all, don’t overthink it.

The word count matters, yes — but not as much as the story, the intent, and your voice on the page.

That’s what makes a manuscript stand out.

If you’re wondering whether your book is the right length, the right shape, or just plain ready — feel free to get in touch. I offer honest, constructive editorial feedback and work with authors at every stage of their journey.

You bring the words — however many — and I’ll help you make them shine.
