Calibri is a sans-serif typeface family designed by Luc(as) de Groot in 2002–2004 and released to the general public in 2007, with Microsoft Office 2007 and Windows Vista. In Office 2007, it replaced Times New Roman as the default typeface in Word and replaced Arial as the default in PowerPoint, Excel, Outlook, and WordPad. De Groot described its subtly rounded design as having "a warm and soft character".
