What Affects the Page Count
Four levers move your final number more than anything else:
- Line spacing. Standard manuscript format is double-spaced. Moving from single to double doubles your page count, which is why a 300-page single-spaced draft becomes a 600-page submission package.
- Font width. Times New Roman and Calibri are narrow, packing more words per line. Arial and Georgia are about 10 percent wider, and Verdana is wider still, which pushes 150,000 words past 660 double-spaced pages.
- Font size. Dropping from 12pt to 11pt shaves roughly 12 to 15 percent off the total. Bumping to 13pt or 14pt adds a similar amount.
- Margin width. The standard 1-inch margin is required by most agents and publishers. Tightening to 0.75 inches removes about 30 to 40 double-spaced pages, but submission guidelines almost always require 1-inch margins.
Genre Comparison: Is 150,000 Words Right?
150,000 words is long. Standard industry word counts vary widely by genre, and 150,000 sits at the upper end or beyond for most categories.
| Genre | Standard Word Count | 150k Status |
|---|---|---|
| Thriller / Mystery | 70,000 - 90,000 | Far too long |
| Romance | 70,000 - 90,000 | Far too long |
| Literary Fiction | 80,000 - 110,000 | Long but possible |
| Historical Fiction | 90,000 - 120,000 | Acceptable |
| Epic Fantasy | 100,000 - 200,000 | Right on target |
| Science Fiction | 90,000 - 130,000 | On the long side |
| YA Fiction | 50,000 - 80,000 | Far too long |
Typical 150,000-Word Use Cases
A 150,000-word manuscript fits these formats well:
- Epic fantasy novel. Brandon Sanderson, Robert Jordan, Steven Erikson, and similar epic-fantasy authors routinely publish books at or beyond 150,000 words. Tolkien's The Fellowship of the Ring is roughly 187,000 words.
- Literary doorstopper. Donna Tartt's The Goldfinch is around 257,000 words, but many literary novels land in the 130,000 to 170,000 range.
- Historical saga. Sweeping multi-generational historical fiction commonly runs 130,000 to 180,000 words.
- Complete academic dissertation. A typical US humanities or social sciences PhD dissertation is 80,000 to 120,000 words. STEM dissertations can be shorter due to figures and equations, but the 150,000 mark fits a comprehensive humanities thesis.
- Memoir or biography. Substantial biographies and memoirs run 100,000 to 180,000 words.
- Nonfiction trade book. Long-form narrative nonfiction such as Walter Isaacson biographies runs 150,000 to 250,000 words.

Tips to Hit Exactly 150,000 Words
Use a word counter to track your progress in real time. A few practical tactics for a novel-length manuscript:
- Outline by chapter. 30 to 50 chapters at 3000 to 5000 words each is far more manageable than a single 150,000-word goal.
- Set daily minimums. Even 500 words a day finishes a 150,000-word draft in 10 months.
- Plan in three acts. Allocate roughly 25 percent setup, 50 percent confrontation, and 25 percent resolution: 37,500 / 75,000 / 37,500 words.
- Cut filler in revision. Most first drafts run 10 to 15 percent over their final length. Trimming sharpens prose and tightens pacing.
- Watch subplot drift. Epic-length manuscripts often pad word count with subplots that do not earn their place. Cut any subplot that does not affect the climax.
Reading and Speaking Time for 150,000 Words
- Reading: About 10 hours at 250 WPM. Slow readers at 200 WPM finish in 12.5 hours, fast readers at 400 WPM in 6 hours.
