| How to Choose the Right Tie Size? Time to buy a tie, but how do you know what's the right size for you? We'll make it easy; there are a few simple rules to follow and you can't go wrong. Appropriate Length
Your choices on tie length are regular and extra-long. Most guys need the regular, standard length tie, which typically runs around 57 inches in length. If you are exceptionally tall (over six feet tall), or exceptionally large (with a neck size over 18), you may need an extra long tie. Extra-long ties typically measures around 62 inches. Extra Long
The easiest way to determine if you need an extra-long tie is by trying on ties and seeing where they fall when tied. A tie of proper length should always hit at least to the top of the belt line. Also keep in mind that a tie that is worn a tad long is almost always acceptable, whereas a tie that is short is never a good look. Appropriate tie width
The idea with tie width is that the measurement at the bell (the widest portion of the tie) roughly corresponds with the width of the same season's notch lapel on suit coats and sport coats. This doesn't mean that the measurements are literally the same. What it does mean is that a wider lapel on the jacket means you'd want a wider tie, and vice versa. Patterns change, and so should your tie wardrobe
Also, in addition to the width of ties changing, the textile designs that accompany these ties are updated. This is why it never works to hold on to ties until they "come back" in fashion. The odds of the appropriate width corresponding to the favored patterns of the day are so long that it is almost always easier to simply purchase new ties as times and style change. Besides, purchasing a new tie is the fastest, easiest, least expensive way to freshen and update a suit you already own. |
