How Wide Should a Tie Be?
With some variations, the standard width of a necktie has remained standard throughout the 20th century. The 1930s gangster look featured wide ties, which reappeared during the 1960s, when ties drew to 5 inches in width. In the 1950s, skinny ties with square ends were in vogue for a while.
Since ties should be in proportion to shirt collars and suit lapels, therefore some fluctuation in width can be expected. However, ties should generally be 3 ¼ inches across at the widest point. The tie then tapers off to the short end.
Ties are available between 52 and 58 inches long. Tall men or those using a Windsor knot may need custom-made ties. When knotted both ends of the necktie should reach the belt. While each end should be roughly the same length, the wider part may be slightly longer.
