Fantasy vs Science Fiction: Which Books Are Longer?


So recently I’ve been reading a lot more fantasy fiction than science fiction, and it began to dawn on me that the average fantasy book is much longer than your average SciFi book. I did some research. Compiled a list of popular books in each genre, and found their word count. It was far easier to find the word counts for fantasy books than science fiction for some reason, and most of them were rounded to the nearest thousand. And although it is a very small pool of books (27 fantasy / 24 science fiction), the average in popular fantasy novels is almost 3x the word count of popular SciFi. 

This list is far from a proper conclusion, as it suffers from the bias of books I’m personally familiar with. But I hope this is a good starting point for an interesting study for some. Why would fantasy books tend to be longer, generally? Writing styles, peer pressure in the writing community, the necessity to build a realistic world, or is it that most fantasy novels are part of longer series? It may also have to do with a lax mentality on publishing companies when it comes to word count in recent years.

  1. Sci-fi does have a long and proud tradition of novellas… My guess would be that sci-fi is more idea-based while fantasy is more world-based. You don’t want to beat the idea over the head, but you do want to show the world in extreme detail.

    Plus, of course, various subgenres… some SF is enormous (Battlefield Earth) and then some fantasy is quite short (most comedic fantasy). There might be more of a divide between the length of a comedy and a drama than between SF and fantasy, but I’d have to find some more numbers to crunch to back that up.


  2. There’s a bit of a sampling problem in that all of your fantasy selections come from a subgenre notorious for padding the word count and dragging out the “epic” story, while your science fiction selections include multiple subgenres including comedy. I suspect you’d get a better sampling looking at awards shortlists.


  3. I prefer to read fantasy on the most part and the serious books tend to be really long, I think, but the comedies like Terry Pratchett, Tom Holt and KE Mills tend to be shorter. I don’t know if you want to throw them into the mix though, they are proabably a different breed altogether🙂

    I read both genre and come to the same conclusion.
    I also write science fiction.
    I find science fiction to be more detail oriented and fantasy character and atmosphere oriented.


  5. Not exclusively, but may also be factors like gender and skill set. Sci-fi writer may tend more to be male with compartmentalized communication and fantasy more female with descriptive communication skills. Sort of Yin and Yang. Or maybe not, just a thought. Interesting since I read both sci-fi and fantasy. Not either, but just finished William Gibson’s Spook Country.


  6. The Malazan Cycle is pretty massive, as are quite a number of Neal Stephenson’s books (I recognize both as scifi works in another link that might help: On the fantasy side, the Sword of Truth series by Terry Goodkind might also be a good series addition.

    I’m mostly a fantasy girl myself, so sometimes I do cringe thinking about the word count for epic fantasies. But yes, it is an interesting thought to see how scifi fares next to the fantasy genre.

  7. I don’t have word counts, but Robinson’s Mars Trilogy, any of Alastair Reynolds’ books, and any of Peter F Hamilton’s books are monsters. They’re all science fiction.
