I recently read a very insightful article by Vincent De Oliveira:
http://iamvdo.me/en/blog/css-font-metrics-line-height-and-vertical-align
In there, he mentions Font Forge and OpenType.js that can load interesting font metrics from a font file. That might a better way of getting various font data than measuring it by hand.
Thought you might be interested in that.
