The proper length for a tie is when the tip of the wide end (the blade) reaches the top of your belt buckle or waistband while standing straight. It should neither hang above nor below this point. This ensures a balanced, polished appearance regardless of the knot style or whether you are wearing a jacket (the tie tip should still be in the correct place even if covered)

Additional Details:

• Standard tie length is typically about 57 to 58 inches, suitable for men under six feet tall.
• Extra-long ties (61 to 63 inches) are recommended for taller men (over 6 feet) or those with broader bodies to maintain proper proportion.
• The tail end of the tie should be tucked into the keeper loop on the back; if it doesn’t reach the loop, the tie is too short, and if it extends far beyond, it’s too long

• Maintaining a natural posture when tying the tie helps ensure the correct length.
• The tie length should look neat and balanced, with the narrow end shorter than the wide end

In summary, the golden rule is: the tip of your tie should rest just at the top of your belt buckle or waistband for the most refined and stylish look.
