Aren't out of the box Styles in Word (2016) like
auto-updating in terms of font size? They show themselves to be "Based on Normal" But, I updated the Normal text size to 18. Then, started using Heading 1 - it was just 16. And, Heading 2 just 13.
I even went further and selected both of these with a check box "Auto Updating".
How can I get my Headings 1 ~ x default styles to update themselves in terms of Font Size in Word?
