Manuscript Editing and Word Count

manuscript editingHow Many Words Are “Just Right?”

Manuscript editing involves much more than correcting grammar. A book editor should be familiar with various genres and know the ballpark word count recommended for each. I’m often asked, “How long should my nonfiction novel/memoir/biography/fantasy/historical/novella be?”

I could easily suggest 55,000 to 100,000 words, but that’s too easy. Each genre has its own industry standard. Knowing the industry standard is key.

I must shout out an excellent blog post by Chuck Sambuchino at Writer’s Digest — one of the best at explaining word count requirements. Sambuchino’s recommendations are as follows, but visit his article to see the entire scope:

Adult novels (literary, mainstream, women’s, romance, mystery, suspense, thriller, horror): 80,000 and 89,999 words

  • Sci-fi and fantasy: 100,000 – 115,000 words
  • Middle grade fiction: 20,000 – 55,000 words
  • Young adult fiction: 55,000 – 79,999 words
  • Picture books: 500-600 words (32 page count)
  • Westerns: 50,000 to 80,000 words
  • Memoirs:  80,000-89,999 words

In fact, check out the Reader’s Digest website for writing tips, manuscript editing tips, and some great interviews with authors and literary professionals. I’ve been a fan of the site forever.

By the way, I’m also a fan of The Write Life, which is filled with inspiration and advice for writers. Blake Atwood at The Write Life also weighs in with word count recommendations, and goes a bit further by breaking down subgenres. Check out his article in its entirety to get the full low-down on word counts.

More on Manuscript Editing and Word Count

Although I suggest authors produce word counts within the suggested frames, there have been instances when word counts broke barriers.

Question: What book series has spanned the highs and lows of word counts?

Answer: The Harry Potter series.

Take a look at the disparity:

  • Harry Potter and the Sorcerer’s Stone — 76,000 words
  • Harry Potter and the Chamber of Secrets — 85,000 words
  • Harry Potter and the Prisoner of Azkaban — 107,000 words
  • Harry Potter and the Goblet of Fire — 190,000 words
  • Harry Potter and the Order of the Phoenix — 257,000 words
  • Harry Potter and the Half-Blood Prince — 168,000 words
  • Harry Potter and the Deathly Hallows — 198,000 words


Emerging authors should stick with recommended word counts. Once you have a literary agent, or have successfully self-published, you may have some leeway regarding the length and robust aspects of your manuscripts. However, remember that industry standards and literary guidelines exist for a reason, and readers have come to expect a specific book thickness when they order online or pick up a copy.
