Yesterday I finished the first draft of a science fiction story I want to submit to the major sci fi magazines. I checked the story lengths the magazines want, and they define a short story as less than 7,500 words and a novelette as 7,500 to 15,000 words. My story is almost exactly 7,500 words long. In my second draft, I want to strengthen and extend a couple of scenes - it'll make the story better. That would put the story squarely into novelette territory. On the other hand, I could trim it a little to make it a proper short story, but it's pretty tight already, and I'm afraid I'd lose something important. That would weaken the story. The magazines publish more short stories than novelettes, so I have a better chance of being accepted, as a first-timer, with a short story, all other things being equal. So, do I lengthen it, making it (IMO) a better story, even if it has a smaller chance of being accepted? Or do I trim it, making it (IMO) a weaker story, but with a better chance of being accepted?
