Text Spacing

Hey!

I have a question about text spacing, as it relates to the accessibility guidelines WCAG 2.1, level AA.

Success Criterion 1.4.12 states that in order to be compliant text spacing can be altered up to the following dimensions without any loss of content or functionality:

Line height (line spacing) to at least 1.5 times the font size
Spacing following paragraphs to at least 2 times the font size
Letter spacing (tracking) to at least 0.12 times the font size
Word spacing to at least 0.16 times the font size.

My question is:
1) Can those 4 features be altered with Rise? 
2) If not, do you have any information you can share for set text sizes? For instance, working with font size 20, what would the letter spacing be, etc.?

Thanks!

Clara
