I love the novella length Kindle Singles section on Amazon. I love Novellas and think there should be more of them. Novellas never get much love because they’re not optimized for the publishing industry. They’re not big enough that people want to pay $8-12 for them. Kindle Singles cost $1-5.
While fiction novellas are great I think non-fiction is really well served at this length. The majority of non-fiction books I’ve read would have been much better at the Kindle Single length, especially business books. They almost always feel bloated so they can reach that magical word count. (Not totally true my friend @FosterThinking's book is the right length.)
- Kindle Singles are 5,000 - 30,000 words and at 250 words a page (which almost all books are) that would be 20-120 pages.
- Short stories are 1,000 - 7,500, which would be 4-30 pages and why they’re usually first published in magazines (or on blog posts) and then packaged in anthologies.
- Novelette (which most publishers usually treat as a novella) are 7,501 - 17,500 words which would be 30-70 pages.
- Novellas are 17,501-40,000 words which would be 70-160 pages.
- The vast majority of books are ~300 pages (especially fiction) but it’s not uncommon to find business books in the 200-250 range.
(Full disclosure, I work at Amazon but have nothing to do with the publishing or Kindle side of the business.)
