For a standard necklace, we would recommend an 18 inch/46cm chain. This falls between the collar bone and chest on most people, but it will depend on your individual anatomy. For smaller frames try a 16-inch/41cm or for larger frames try a 20-inch/51cm. We’re proud to stock a wide range of chains in a variety of lengths so we’re sure we will have something just right for you.
