I keep repeating this lately :) : check out tachyons.css and react-native-tachyons (the latter is a port by me)

It uses fixed scales for spacings, typography etc. which are relative to rootfontsize.

Thanks for the link to tachyons css. Was just searching for a modular system exactly like this. Plus, great name ;)
