Can you please give a definitive answer about word count. While I understand 100K is way too much for most genres, what is too little? Is anything under 80K, for mainstream fiction, too little and instant rejection?
Has NaNo, with its 50K word counts, killed chances for hopefuls in that range?
100K isn't "way too much" for most genres. It's right on the mark for many, and too few for a couple others.
Here's the rundown:
Sweeping, epic fantasy: 150K at a minimum. You can't do it right in less.
Sweeping, epic, historical fiction: 120 at a minimum. More is better.
Science fiction novels: 75-125K
Womens' fiction: 100K and up
Crime novels: 80-100K
Noir novels: 65K and up but only double digits here, not triple.
Picture books: fewer than 2000 words
While NaNoMo sets a goal of 50K, that's for your FIRST DRAFT. Get that draft on paper and then go back and see where you need to develop the story, develop the character.
If you can't see where you need to expand, give it to a beta reader and ask where they have questions, or felt like they hadn't gotten enough story.
The bottom line is word count isn't something you want to worry about till revisions. Use enough words, and no more, to tell the story fully and completely.You have to be WAY WAY outside the paramenters on word count before it's an auto rejection. And even then, if your pages are well written and taut, I'm going to give you the benefit of the doubt. Worry less about how many words you've got than do you have the RIGHT words.
