One Ratio Beats Eight Decisions
Picking every heading size by eye is how a page ends up with an h2 and an h3 four pixels apart. A modular scale sets one ratio and derives the rest, so the hierarchy is a decision you make once.
We use this on every site we build, including this one. If you would rather hand the whole problem to someone else, that is the day job.
