WCAG provides a definition of what it means at

You should base it off the default font size for standard browsers. 14
and 18 point would be 1.2 and 1.5 em or 120% and 150% of the default
size for body text. As long as you're using relative font sizes, you
don't need to worry about the actual pixel size of the rendered text -
just worry about how much bigger the text is proportionally to the
default (100%) font size.

Hopefully that makes sense.
