Point is NOT relative to the parent. "larger" and "smaller" are relative to the parent.
Point is a number of pixels which varies by system.

(There are also percentages and ems for sizing, but unless you're designing a "liquid layout" there's not much reason to use those.)

Where "liquid layout" means "a site that works on your customer's screen as well as your own.
Agreed, there's not much reason to use percentages or ems if you are the only one viewing the site.
On the other hand, if have, or want to have customers, and want your site
to look good for potential customers, that when you want ems or percentages.
