Host Grotesk is a modern uniwidth sans-serif typeface designed specifically for user interfaces. Available in five weights with corresponding italics, it offers uniform letter width and spacing, ensuring seamless adaptability and layout consistency. Its uniwidth nature allows for smooth transitions between font weights without disrupting design coherence. This means, for example, that a button's size remains constant even when the font weight changes on hover. Host Grotesk is ideal for both display and text applications, featuring a monolinear stroke, closed terminals, and simple letterforms. Its proportions, falling between a generous geometric sans and a compact grotesque, make it suitable for various display sizes and small body copy. This open-source typeface, built upon Jonny Pinhorn's popular "Poppins" font, retains a soft and approachable essence while offering a fresh, cohesive aesthetic. Host Grotesk is a reliable choice for user interfaces, branding, and communication materials, combining contemporary design with the enhanced functionality of uniwidth proportions.
