The length of the chain portion of this eyeglass holder is approximately 27". The overall measurement of this eyeglass holder, including the eyeglass pieces, measures approximately 29". The black eyeglass pieces are adjustable! Simply move the silver coiled metal piece so it will hold tight to the ear wires of your glasses. (Be careful not to over tighten.)
