Growing up in the western world, chances are that the Four-in-Hand will be the first necktie knot you ever learn to tie, and it very well may be the only knot you ever need. Also known as the schoolboy knot or the simple knot, the Four-in-Hand is quite easy to tie and can be mastered with very little practice. Follow the steps below and you'll be all set.
Begin with your shirt buttoned, collar turned up, and drape the tie around your neck with the narrow side on the right. The tip of the narrow side should be roughly level with your navel.
Take the wide end of the tie and bring it across the narrow end as shown.
Bring the wide end of the tie back behind the narrow end as shown.
Wrap the wide end of the tie back across the front of the narrow end once again as shown.
Pinching the center to hold your wrap in place, now lift the wide end of the tie up and through the main loop, behind where the final knot will be.
Bring the wide end back down, feeding it through the loop you just made so that it will rest above the narrow end of the tie.
In a simultaneous motion, pinch the knot up and tug the wide end of the tie down to tighten the knot. Ideally the tip of the wide end will rest between the top and bottom of your belt buckle. Bring the shirt collar down, smooth it out, and you're done!
If the tie is too short or too long, tug on the knot to undo it and simply start over. If your first attempt was too long, lengthen the narrow end in Step 1. If your first attempt was too short, shorten the narrow end in Step 1.
