I'd like to try submitting something to a magazine to be published
RelevantI'm considering a few local magazines,
Local is good. It's convenient to be able to walk into the office to meet with people. And if I'm deciding between two articles of equal quality and relevance, I'm more likely to choose the writer five miles away than the writer in another state. Especially for local interest stories. It won't matter as much with fiction, but I'll obviously be more trusting of the guy next door to review the local golf course than I will the guy in Kentucky.
Just don't
limit yourself to local publishers.
I tend to write fairly soft sci-fi
Note that fiction is notoriously difficult to get into, because there are so ridiculously many people wanting to write it. Gone are the days that every aspiring author first got published in Amazing Stories. There's far more demand for relatively boring things like product reviews, teen kissing guides, travel stories, stories about what Paris Hilton's dog did at her last psychiatrist's appointment, etc.
are there any magazines that come recommended?
Any magazine that caters to topics that personally interest you and that you have interesting and relevant anecdotes about. Checking google...here's a
consolidated list of guidelines for 853 different periodicals. Pick a category that interests you and go down the list.
what are standards going to be like? Especially regarding length and format.
It varies. Be absolutely certain to read the writer's guidelines for
each and every single magazine you submit to. Don't plan to write an article and then submit it. Read the writer's guidelines first. Ideal length for a National Geographic Traveler feature article is 1500-2500 words. Average for Scientific American is 2500 words. Forbes expects their guest submissions to be 850-1000 words. If you're writing for The Escapist, they'll tell you in advance exactly how long they want it if they accept your pitch. It varies.
Also, get the magazine in question and read it. Seeing what they've previously published should give you an idea what they're likely to publish in the future.
is there anything important I'm missing?
Note that most "big" magazines don't accept unsolicited submissions. They instead require that you submit a pitch, and they'll respond with whether they're interested. Identify in advance the particular policy of the magazine you intend to submit to, and follow their rules. They don't generally make any great secret of it. If you can't be bothered to find out their process, they're unlikely to bother considering your submission.
Understand that most magazines anyone would recognize by name primarily publish material written by staff writers.
It's generally acceptable to submit identical pitches to multiple publishers simultaneously, but if you do this you
absolutely must keep everyone informed and
do not accept identical commissions from multiple sources unless they explicitly approve it. They will find out and you will be blacklisted. If one editor accepts your pitch, immediately inform the others you've submitted to. In the case of periodicals that accept unsolicited submissions, again, inform them if you've submitted to multiple publishers and immediately inform everyone else once you've been accepted.
