Windsor knot

A necktie knot

The Windsor knot, sometimes referred to as a full Windsor to distinguish it from the half-Windsor, is a knot used to tie a necktie. As with other common necktie knots, the Windsor knot is triangular, and the wide end of the tie drapes in front of the narrow end. The Windsor is a wider knot than most common knots, and while not truly symmetric is more balanced than the common four-in-hand knot. The Windsor's width makes it especially suited to be used with a spread or cutaway collar.
