You might think typography and math have nothing to do with each another, but Pearsonified's Golden Ratio Typography Calculator proves the opposite: The web calculator provides, based on font size and line width, the optimal line height according to the most harmonious proportion - the golden ratio.
When nature needs a proportion to relate things and to provide order on any scale, it tends to use the golden ratio.
So far it was almost impossible to integrate Pearsonified's web calculator in a productive workflow, because you had to enter most values manually. To simplify this process I created a free Sketch plugin, which automatically calculates and applies the golden ratio line height.
Note to designers: This plugin is intended to only serve as a basis for proper typesetting. For instance I only use it for setting up quick layouts or prototypes - not final designs.
