Don't you mean novella? A novellette is between a short story and a novella, typically under 20,000 words.
Duh (hits self on head). I realized my mistake after going to bed last night. Novellas are typically (historically) defined as 30,000 to 50,000 words.
In the past I've seen other author websites listing novels as anything over 40,000 words, and some publishers listing 50,000 to 75,000 words as typical novel lengths. I've also seen some publishers listing a maximum size of novels as 100,000 words re the equivalent of two novels together in their words.
It all depends on the individual publisher, and which genres they publish. I'm talking about the mainstream, big-name publishers spanning the last 50 years, rather than an exotic, specialty publisher. Again, we're talking ballpark here, and some will go under while others will go way over, often depending on the popularity of the author rather than any other criteria. I was responding to Aubie, asking whether readers might be offended by the length of his stories. Based on historic trends and the comments posted here, I'd say yeah, some likely will be. However, I'd guess most readers already know what to expect from Aubie and Ernest by now, so I doubt they'll be surprised by anything. Though you've got to admit, Ernest, your combining chapters to reach the magical posting side of 8,000 words is a tacit public admission that readers are concerned with reading size, even if you keep your total book lengths relatively short.
I've seen 35,000 word dead-tree books described as 'short novel' in reviews. Novels seem to be shrinking as well as growing fatter.
That's likely because novellas have long had a bad image problem as 'artsy' and pretentious, thus many publishers will likely group them under 'novels' simply to avoid pissing potential readers off.
