This question has been pestering me for years. A lot of people say you should use one inch wraparound, but it takes a lot more to fill a page that way, even when you're using an editorial word count (250 words per page).
I have a copy of "The Writer's Market" dating back to 1993, which recommends 1.25 inch margins and I even know writers who use 1.5 inches, which would be seventh heaven with Courier New and 12 point font and counting words with an editorial word count.
I know, I know, it's quality, not quantity, but when you have your story and it's lean, mean and hungry to earn some green, it seems ridiculous to have to pad him until he's a wheezy, adipose porker.
I think you're confused about how word count works. The editorial 250 words per page rule is not an estimate, it's an actual count of spaces per line. So if you widen the margins, you then have to count the actual spaces and adjust accordingly.
Editorial word count only works easily with one inch margins. If you use wider margins, you have to change the number of words you assign each page. Only one inch margins give you the 250 words per page rule.
Margins have nothing at all to do with padding. One inch margins gives you an average of sixty spaces per line. You divide this by six which means ten words per line. You multiply this by twenty-five lines per page, which gives you the 250 word per page count.
You're free to use 1.25 margins, or 1.50 margins, if you like the look, but you then have to count the spaces per line, divide by six, and multiply by twenty-five, which gives you a lower word count per page that the one inch margins.
So if you use 1.25 or 1.50 margins, you then have to write more pages to bring your word count up to what publishers want.
Wider or narrower margins simply don't give you more or less writing, and do not take away or add length.
With one inch margins and Courier 12, 400 pages is counted as 100,000 words. With 1.5 inch margins, you only average 52 spaces per line, so it takes about 461 pages to get this same 100,000 words.
One inch margins just makes the math work easier. It gives you sixty spaces divided by six instead of 52 spaces divided by six, and lets you multiply the lines on the page by ten instead of by 8.6.
So padding has nothing to do with it, and lean writing has nothing to do with it. When a publisher wants a 100,000 word novel, this means 400 pages with Courier 12 and one inch margins at twenty-five lines per page. But if you use 1.5 inch margins because you like the look, you then have to give that publisher 461 pages with Courier 12, 1.5 inch margins, and twenty-five lines per page.
So no matter what margins you use, you still have to write the same amount. The only question is how easy do you want the math to be, and how much paper do you want to use to print the novel.
