Calibri Bold

Calibri Bold is a modern humanist sans-serif typeface designed by Luc(as) de Groot between 2002 and 2004. It was officially released to the public in 2007 as part of the Microsoft ClearType Font Collection, appearing in Windows Vista and Office 2007. Designed specifically to enhance readability on digital screens, it utilized Microsoft's ClearType rendering technology to provide a crisp, clean appearance on LCD monitors. It famously served as the default typeface for the Microsoft Office suite for over 15 years.

The typeface is defined by its subtly rounded stems and corners, which are visible at larger sizes and provide a warmer, more approachable aesthetic than traditional neo-grotesque sans-serifs. With its high x-height and open counters, Calibri Bold maintains exceptional legibility even at small point sizes. This makes it a versatile choice for everything from dense corporate reports to sleek digital interfaces, bridging the gap between professional formality and modern digital design.
