The Half Windsor knot is the smaller brother of the popular Windsor knot - also known as Double Windsor or Full Windsor knot. The half Windsor is, just like the Four in Hand knot, a smaller tie knot. When compared to the Four-in-Hand, the half Windsor is a little thicker and a touch wider. Tie this type of knot for medium-width collar spread dress shirts.
Step 1 - Take the wide end of the tie and cross it behind the narrow end
Step 2 - Now take the wide end of the tie and loop it over the narrow end. The “good side” of the necktie should be showing now.
Step 3 - Wrap the wide end of your necktie between your neck and the tie and pull through the loop.
Step 4 - Slightly pull tight, center the knot, and flip over you collars. Finished!
