Font-To-Width
Font-To-Width (FTW!) is a script by Nick Sherman and Chris Lewis that fits text snugly into its container by choosing among the width or weight variants of a large type family, instead of scaling font-size the way FitText.js does. Once it picks the best-fitting variant, it fine-tunes with letter- and word-spacing adjustments. The post notes that improvements are on the way, that the current version is available on GitHub, and that its demo, modeled on Jason Santa Maria's photo of shuffleboard standings, uses all six widths of Production Type's Panorama.
