How to Choose Your Science Fiction Niche
Research Amazon Bestseller Lists
Browse the Science Fiction bestseller charts on Amazon. Look at the top 20-50 books — their covers, titles, blurbs, and reviews tell you what readers want right now.
Analyze Competition Levels
Use our BSR Sales Calculator to estimate how many sales the top books are getting. A category where the #1 book has a BSR above 5,000 often has room for new authors.
Find Underserved Sub-Genres
Look for sub-genres where readers are asking for "more books like this" in reviews. These gaps represent opportunities for your science fiction book.
Match Your Expertise & Passion
The best science fiction books come from authors who genuinely understand and love the sub-genre. Your enthusiasm will show in the writing.
Test with Short-Form Content
Before committing to a full novel, test your concept with a short story or novella. Reader response will tell you if your niche has demand.
Science Fiction Writing Tips
- Ground your science in real principles, then extrapolate
- The technology should create unique human dilemmas
- World-building should feel lived-in, not like an info dump
- Character development matters as much as the concept
