Simple answer: Wear the tartan(s) you have a connection with. Most tartans are clan tartans and each clan is associated with multiple last names. Use our tool to see which clans your family is connected with, and choose whichever tartan you like best. There are three types of tartan associations: (1) Clan/related family, (2) Organizational, and (3) Regional tartans. Each of the 200+ Scottish clans have multiple tartans. For example, a clan may have a modern tartan, an ancient tartan, a tartan for formal occasions, another for hunting, or a tartan that is woven in more muted (weathered) colors. Additionally, all of these different tartans can be woven in heavy (16 oz) medium (13 oz) and light (11oz) weight fabric. Most kilts are made using heavy (16 oz) weight fabric. “Whats My Tartan” presents you with each one of those tartans and in each weight available, as options. With this information, you are familiar enough with tartans to search our database of Scottish and Irish tartans to find your family's or clan's tartan.
