Before you finish
A quick check makes a better result.
OutMonkey is built to be simple enough for someone doing this once and useful enough for someone who does it every day.
Good to know
Treat the maths as a starting point.
Look at the result at the size it will really be used. Fonts have different proportions, so spacing that is mathematically neat can still look too tight or too loose.
Typography is partly optical. If two settings are close, choose the one that is easier to read rather than the one with the tidier number.
In plain English
You do not need to be an expert.
Designers can use the numbers as a fast baseline. Everyone else can simply compare the previews and choose the version that is easiest to read and looks balanced.
Type maths gives you structure; the final judgment should still be optical.
