YWFT Caliper was originally created as a unique-yet-readable bitmap typeface. While it works well onscreen at small point sizes, it also can be used at larger sizes for retro-style headers and attention-grabbing statements. YWFT Caliper also contains two free bonus design styles that explore alternate and very unique letter options. These extra styles (called "Stairstep" and "Cube") are what set Caliper apart from the rest of the pixel fonts out there on the grid. YWFT Caliper was converted and updated to Opentype format in 2010.
