Cut structurally before you cut line by line. Removing a subplot loses 20,000 words and usually improves the book; tightening sentences across 140,000 words loses 8,000 and takes three months. Most over-long manuscripts have one whole strand doing very little, and finding it is the entire job.
Your manuscript is 140,000 words
Where the limits actually are
Debut limits, which are stricter than published-author limits. An established author can hand in 160,000 words; a debut usually cannot.
| Genre | Typical debut range | Where it gets difficult |
|---|---|---|
| Literary / general fiction | 80,000–100,000 | Over 120,000 |
| Crime / thriller | 80,000–100,000 | Over 110,000 |
| Romance | 70,000–90,000 | Over 100,000 |
| Fantasy / science fiction | 90,000–120,000 | Over 150,000 |
| Historical fiction | 90,000–120,000 | Over 140,000 |
| Memoir | 70,000–90,000 | Over 110,000 |
| Business / self-help | 50,000–70,000 | Over 80,000 — usually padding |
| Young adult | 60,000–90,000 | Over 100,000 |

Why length matters to a publisher
Paper and printing, mostly, plus risk. A longer book costs more to produce and print, and a debut is an unproven bet — a publisher taking a chance on an unknown author would rather take a cheaper one.
It is also a proxy. In a slush pile, an unusually long debut suggests a writer who has not yet learned to cut, and agents read that signal before they read the book.
For self-publishing the arithmetic is different but not absent: print cost rises with page count, and a 500-page paperback priced to cover it will struggle against 300-page competitors.
Structural cuts first, always
This is the whole method.
Look for: a subplot that resolves without affecting the main story; a viewpoint character whose chapters could be summarised in two paragraphs; a section of backstory delivered as scenes; the first two chapters, because a great many novels begin at chapter three; and a middle act holding position rather than escalating.
One of those is typically 15,000–30,000 words, and removing it usually makes the book better rather than merely shorter. Line-level tightening across the whole manuscript recovers perhaps 5–8% and takes far longer.
Then the line-level pass
Once the structure is settled, the line pass recovers another 5–8%.
What to look for: dialogue tags doing work the dialogue already does; a strong sentence followed by a weaker one repeating it; description of things the reader has already been shown; adverbs propping up weak verbs; characters explaining plot to each other for the reader's benefit.
Do this after the structural cuts. Tightening prose in a chapter you are about to delete is the purest form of wasted effort in writing.
What Your Book Pro does here
Your Book Pro is a British book-writing platform. You bring a book — an idea, a folder of notes, half a draft, or a finished manuscript written somewhere else — and it gives you the editorial process a publisher would run: a plan, structured feedback, a simulated beta read, a line edit, a proofread, a cover, a blurb and a print-ready file. You can type it, upload it or speak it. The tools sit in one place and work on the same manuscript, so the feedback compounds instead of arriving as twelve disconnected opinions.
Detailed Editorial Feedback is built for exactly this question. Reading the whole manuscript at once, it reports which strands are load-bearing and which are not — the subplot that resolves without consequence, the three chapters where nothing changes, the viewpoint that could be cut. That is the £1,500–£4,800 conversation, and it costs 600 credits, inside your free welcome credits.
Light Edit then handles the line pass, removing filler and repetition without rewriting your wording — so the cut does not flatten your voice on the way through.
Keep a cuts file. You will restore about a tenth, and the rest often turns out to be the beginning of something else.

- How long is too long for a debut novel?
- Over 120,000 words is difficult for most genres, though fantasy and historical fiction have more latitude. Under 60,000 is a different problem.
- Do agents really reject on word count?
- Some do, at the query stage, before reading. It is a crude filter and it is real, which is why the number in your query letter matters.
- Does this matter if I'm self-publishing?
- Less, but print cost rises with page count and readers do notice pacing. A book that is 30% longer than its shelf-mates usually reads as slow rather than generous.
- What if I can't find anything to cut?
- That is almost always a sign you are looking at sentences instead of structure. Reverse-outline by what changes in each chapter, and the passengers become visible.
