Baseline ratios

This table contains the baseline ratios for some of the most popular fonts found on desktop, Google Fonts and Typekit. Use these numbers as the $baseline parameter of the Plumber mixin.

If you don't see your chosen font family here, use the measure tool, or if you have access to the OpenType metrics of the font you can calculate a more precise baseline ratio with the following formula:
(UnitsPerEm − hhea.Ascender − hhea.Descender) / (2 × UnitsPerEm)
