This is where most people freak out about résumé writing. When you hear people bitch about font choice, font size, margins, bolding, indenting and capping, all they're worrying about is making the résumé pretty. We have several good tips on how to make your résumé easy to read.
Less is more
Take out as many articles (e.g., "the," "an") as possible. Don't over-explain things. And it's OK to have white space on the résumé. It makes it easier to read. Along the same lines, do not justify the margins of your résumé (they sometimes make sentences look weird, because it forces the spacing). Instead, make the right margin "jagged."
Make sure your name stands out
Type your name in a bigger font, put it in all capitals, bold it---do whatever you have to do to make sure your interviewer can glance down and easily read your name. If your name happens to sound gender-neutral (e.g., Robin Williams, Jamie Gumm), try adding your middle name if it helps clarify things. If it doesn't (e.g., Soon Yoo Park), it is acceptable to place a "Mr." or "Ms." In front of your name.
Do not use wacky fonts
Unless the potential job is in advertising, design or some other creative field, stick to the traditional, easy-to-read fonts, such as Times, Palatino, Helvetica or Ariel. There is a very good reason for this: Many companies scan received résumés into a computer. If you have crazy fonts, the computer will mis-scan your résumé, and all the reader will see is gobbledygook. Along the same lines, make sure you don't fold the résumé along a line of text, or the ink could flake off.
Highlight what you want to be read
The most important items should be bolded, underlined, capped or highlighted in some way that will draw attention to them. For instance, the name of your college and the name of each company you worked for should stand out.
Be consistent
Whatever you do---be it with capitalization, italicizing, bolding or indenting---keep it consistent throughout the résumé. If you don't, the reader will think either that you screwed up or that you don't pay attention to detail.
There are thousands of pieces of advice we could give about formatting your résumé, but the best advice we could give is for you to look through different examples, see which one you like the best, and copy the style. Don't worry, it's not stealing unless you copy all of their employment history, too. We highly suggest Yana Parker's book, "Résumé Catalog: 200 Damn Good Examples."
