How do I change the size of a subformula?

There are five variants of the size-changing command:

  • size 20 a typesets a with the font size 20 pt.
  • size +5 a typesets a with current font size plus 5pt.
  • size -5 a typesets a with current font size minus 5pt.
  • size *1.5 a typesets a with current font size times 1.5.
  • size /1.5 a typesets a with current font size divided by 1.5.

You can change the font size of an entire subformula if you group it with { } or other brackets. Example:

  • Enter a b size *2 {c d} e to typeset abcde.

When several font size changes are applied, the innermost takes precedence as shown in this example:

  • Enter size *1.5 {a size 12 b size *1.5 c d} to get abcd.

To change the base font size used in Math see FAQ #008.
