I'm afraid the default line-height is unpredictable, it varies among readers and browsers, but I'd say it's typically around 1.1-1.2 em.

The "right" line-height is also different depending on the font (and the user). Some fonts are created such that their characters completelly fill the em-box, and sometimes even spill outside of it. If, for these fonts, you use a line-height of 1em (which means the em-boxes are just stacked with no space), the characters in consecutive lines can touch and overlap. Some other fonts have their characters defined completelly inside the em-box, and with some breathing space above and below. For these fonts a line-height of 1em may look fine, but, for a given font-size, the characters look smaller. (See here.)
