Word Count Freedom
Many indie-publishing authors want to know how long their books "should be." The long and short of it: book lengths don't matter. Stories matter.

Many indie/self-publishing authors want to know how long their books "should be." Here are my thoughts on the subject. The long and short of it is that book lengths don't matter. Stories matter. The good news is that indie authors have more freedom to write the story they want.
One of the beauties of self-publishing is that we have more leeway to tell the story we want/need to tell. Traditional agents, editors, and publishers push books into a "standard" range of book lengths and force new authors toward the lower end because they cost more to publish.
NOTE: Publishers know the industry, so they might be right.
YOUR STORY
The most important thing you need to keep in mind is that it is your book and your story, so make the story as long or short as it needs to be. While articles and blog posts may need to focus on brevity, books are, by definition, long-format. That gives you the freedom to choose whether to write a tome or a quick read.
If you drone on to pad your book, you won't be true to yourself and your readers will notice. Because you write for yourself and toil endlessly to share your hard work with the world, it would be a shame to ruin it.
If you cut the book by skimping on the setting, mood, character arc, or plot, you will lose your interest in the work and leave readers wanting. Let your pages shine.
Consideration: Longer books cost more to print, meaning higher print costs.
GET FEEDBACK
Once you've written the story you want, put your words in front of trusted beta readers to get their impression. Are you boring them with long exposition? Are you losing them in the details? Does your main character have enough emphasis on the page? It is easy to be too close to our writing to see it from an objective viewpoint. Your readers have fresh eyes, so they can ground your work in a way that will resonate with other readers.
Resources: This post may help you get your head around feedback.
Here are a few important things to remember about getting feedback.
Always be gracious.
They're trying to help, not hurt.
They aren't always right.
They raise issues, not fixes.
They must enjoy/read your genre.
Always be gracious (Intentionally repeated).
THE LANDSCAPE
If you aren't the type to jump into data, that's okay. The gist of what will follow is that your books can have wildly different lengths than "industry standards." Average book lengths vary by genre, but individual books can be half or double the standard within that genre and still be phenomenal.
Note: Readers almost never look at book length before buying/reading.
Book lengths may range drastically within a single series. The longest or shortest may be at the beginning, end, or somewhere in the middle. The authors wrote the stories as they needed to be told.
THE DATA
GENRE RANGES
Different genres have different average lengths and ranges for the "standard books." While readers almost never look at a book-length online, some pay more attention when browsing in brick-and-mortar stores. Many successful books break these industry standards.
Fantasy & Sci-Fi: 90-130k
Mystery & Thriller: 70-100k
Literary Fiction: 70-100k
Romance: 70-100k
Historical Fiction: 80-120k
Young Adult: 50-80k
Middle Grade: 20-55k
Memoir: 50-90k
Nonfiction: 50-80k
ONE GENRE
Within a genre, the lengths vary more than most people would have you believe. Because I know Sci-Fi the best, here are some great Sci-Fi novels from very successful indie-published books and their word counts.
The Space Legacy Series (Self-Pub): 90-115k
Expeditionary Force Series (Self-Pub): 130-215k
Wool Omnibus: 180k
Undying Mercenaries: 120-180k
Note: Longer audiobooks are more expensive to hire narrators.
VARIATION IN SERIES
Books within a series can have wildly different lengths. Usually, the first book is the shortest, and later books are longer. To give you a sense of some of the variation in novel length within a single series, here are some of my favorite traditionally published Sci-Fi novels.
Bobiverse Series: 96-204k
Undying Mercenaries Series: 130-190k
Red Mars, Green Mars, Blue Mars: 290-385k
Lost Fleet Series: 115-135k
Mountain Man Omnibus (Apocalyptic): 335k
Arison Series (Apocalyptic): 60-220k
Rebel Fleet Series: 125-145k
Note: These are highly successful books by established authors, so the results may be skewed.
SINGLE-AUTHOR VARIATION
To put my words where my mouth is, here is where my books stand. As you can see, they are all over the place. Sci-Fi tends to run longer than other genres, so this biases my expectations of what a novel should be. I'm not saying my books are selling like hotcakes, but this gives you a sense of where I stand.
Day After Infinity (Hard Sci-Fi): 104k
Metal (Apocalyptic): 124k
Nanoverse Series (YA - Superhero): 93-113k
ENDED Series (Hard Sci-Fi - In progress): 140-165k
TRADITIONALLY PUB'ED BOOKS
