The Equilateral Triangle of a Perfect Paragraph is a theory developed by Matej Latin in the Better Web Type course about web typography for web designers and web developers. Too many of them still set line-height, font size and line width as independent features when in fact they should all be considered together. The equilateral triangle is a perfect representation of how the three features work in harmony. The theory is explained in details in an article on CSS-Tricks.
