Those are text figures, not titling figures. They can also all be of the same height (called titling figures), or they can have ascenders and descenders, as in this current font: 123456789. Or they can be all of the same width, as used in tables. There they have idiosyncratically used 20 th rather than 20 th, but the point is that the letters and numbers - more properly, the figures - look different.įigures can be proportionally spaced like letters, and so a digit 1 would take up less room than a digit 4. If you can do full typesetting, then you probably want to make the th part look different from the 20 part, just like they do here: To some extent, it depends on the font you are using and how accessible its special features are.
