The Ducktail beard derives its name from the shape of a duck’s tail. While the name sound hilarious, this is a professional-looking and high-maintenance beard style. The most distinguishing features for the Ducktail beard are pointy chin and short sides. While there are no strict rules for the length, most Ducktail styles have length sizes between 2 and 4 inches. To choose the ideal length for you, consider your face shape and the thickness of your facial hair.
