There a few fundamentals to live by if you want your content to standout without any additional styling, until you learn them, you’ll always feel why some people just have amazing typography in their designs etc. and it almost seems like magic.

1. The ty­po­graphic qual­ity of your doc­u­ment is de­ter­mined largely by how the body text looks. Why? Be­cause there’s more body text than any­thing else. So start every project by mak­ing the body text look good, then worry about the rest.In turn, the ap­pear­ance of the body text is de­ter­mined pri­mar­ily by these four ty­po­graphic choices:
2. Point size is the size of the let­ters. In print, the most com­fort­able range for body text is 10–12 point. On the web, the range is 15–25 pix­els. Not every font ap­pears equally large at a given point size, so be pre­pared to ad­just as necessary.
3. Line spac­ing aka Line height is the ver­ti­cal dis­tance be­tween lines. It should be 120–145% of the point size. In word proces­sors, use the “Ex­act” line-spac­ing op­tion to achieve this. The de­fault sin­gle-line op­tion is too tight; the 1½-line op­tion is too loose. In CSS, use line-height.
4. line length is the hor­i­zon­tal width of the text block. Line length should be an av­er­age of 45–90 char­ac­ters per line (use your word-count func­tion) or 2–3 low­er­case al­pha­bets, like so:abcde­fghijklmnopqrstu­vwxyz­abcde­fghijklmnopqrstu­vwxyz­abcd

   In a printed doc­u­ment, this usu­ally means page mar­gins larger than the tra­di­tional one inch. On a web page, it usu­ally means not al­low­ing the text to flow to the edges of the browser window.

5. And fi­nally, font choice. The fastest, eas­i­est, and most vis­i­ble im­prove­ment you can make to your ty­pog­ra­phy is to ig­nore the fonts that came free with your com­puter (known as sys­tem fonts) and buy a pro­fes­sional font (from Font Squirrel or a Typekit subscription if you want to use multiple fonts). A pro­fes­sional font gives you the ben­e­fit of a pro­fes­sional de­signer’s skills with­out hav­ing to hire one.If that’s im­pos­si­ble, you can still make good ty­pog­ra­phy with sys­tem fonts. But choose wisely. And never choose Times New Ro­man or Ar­ial, as those fonts are fa­vored only by the ap­a­thetic and sloppy. Not by ty­pog­ra­phers. Not by you.

That’s it. As you put these five rules to work, you’ll no­tice your doc­u­ments start­ing to look more like pro­fes­sion­ally pub­lished material.
