Something that has always bugged me, the vague and misleading terms used by some authors to describe the length of their work. Now, while there is no one set official designation for any fiction classification, labeling a 5000 word short story a novella is just wrong. I've searched the internet for a consensus of what descriptor reflects an accurate word count and what I've gotten is:

microfiction: up to 100 words
flash fiction: 100-1000
short story: 1000 - 7500
novelette: 7500 - 20,000
novella:  20,000 - 50,000
novel: 50,000 - 110,000
epic: 110,000 +

Which is fine, but who decided on 110,000 words being the top end of a novel?
