Railroad ties are rectangular timbers that measure approximately 8 feet 6 inches long, are 9 inches wide, and are 7 inches thick. As the name implies, these huge wood pieces are used in the base of railroad tracks.
The difference between a regular tie and an extra-long one is three to four inches. Regular-length ties are normally 58/59 inches, whereas extra-long ones are usually 61/62 inches long. As a rule of thumb, take your height in inches, and add your necksize in inches to it. If the number exceeds 91 inches you are better off with XL neckties.
