Divide by Zero discussion

Does anyone have a good list of appropriate word lengths for different types of book? Here are the numbers I've heard...

90,000 long novel
70-80,000 average novel
50,000 YA novel
40,000 children's novel or chapter book
20,000 novella
10,000 novellette
5,000 short story
1,000 short short story
100 drabble
50 dribble
25 drip

I use the Fiction Factor page for my word counts: http://www.fictionfactor.com/articles...

But word counts do tend to vary quite a bit depending on magazines, publishers and apparently even countries.

That's a great link. Thank you!
