In the homepage editor, you'll see that the font sizes are displayed in rem values rather than px. This is because rem values are more flexible and allow for site-wide adjustment of font size and weight by editing the Base Size in the Font menu in General Settings.
Equivalent values of px to rem using default 16px base size:
