How thick should a man's necklace be?

How thick a man's necklace should be depends largely on personal preference. Most men's necklaces are at least 2 millimeters thick, and you can find pieces with thicknesses of up to 10 millimeters. The thicker a necklace is, the heavier it will feel and the more noticeable it will be, so choose the size that appeals most to you. If you plan to wear a pendant on your necklace, measure the bail to ensure the chain you choose will fit. Explore a wide variety of necklaces for men on 1stDibs.
