Designed by Nikola Kostić, Allotrope is a sans serif font family. This typeface has one hundred styles and was published by Kostic Type Foundry.
Allotropes are different structural forms of the same element and can exhibit quite different physical properties and chemical behaviors. The change between allotropic forms is triggered by the same forces that affect other structures – pressure, light, and temperature (From Wikipedia the Free Encyclopedia).
With ten weights in five widths plus Italics, this family comes to a total of 100 fonts. The large number of styles was made with the intent to cover most cases UI designers have to tackle, with one type family. Stylistic alternates were made to follow the same logic, so there is an optional single-story g, serifed capital I, and dotted zero – all available through the OpenType feature. The character set supports Western and Central European languages, as well as Turkish.
