Text figures

Text figures (also known as non-lining, lowercase, old style, ranging, hanging, medieval, billing, or antique figures or numerals) are numerals designed with varying heights in a fashion that resembles a typical line of running text, hence the name. They are contrasted with lining figures (also called titling or modern figures), which are the same height as upper-case letters. Georgia is an example of a popular typeface that employs text figures by default.
