Short story: < 7,500 words.

Novelette: 7,500 to 17,500 words.

Novella: 17,500 to 40,000 words.

Novel: > 40,000 words.

Those are the classifications used in the Nebula Awards, which is quite fitting, considering we're a science-fiction wiki. At 33,373,858 words (and counting) this works out as something like at least 4,450 short stories, 1,907 to 4,450 novelettes, 834 to 1,907 novellas or at most 834 novels.
