In the example to the right, the letter 'p' has a descender; the other letters sit on the (red) baseline.

Most, though not all, typefaces are similar in the following ways as regards the baseline:

capital letters sit on the baseline. The most common exceptions are the J and Q.Lining figures (see Arabic numerals) sit on the baseline.The following text figures have descenders: 3 4 5 7 9.The following lowercase letters have descenders: g j p q y.Glyphs with rounded lower extents (0 3 5 6 8 c C G J o O Q U) dip very slightly below the baseline ("overshoot") to create the optical illusion that they sit on the baseline. Peter Karow's Digital Typefaces suggests that typical overshoot is about 1.5%.

The vertical distance of the base lines of consecutive lines in a paragraph is also known as line height or leading, although the latter can also refer to the baseline distance minus the font size.
