Use the guide below to work out how long you want your necklace to be. The guide is there to help you make a choice but please bear in mind that we are all different shapes and sizes so the fit may be a little different for you.

16" (41 cm) NECKLACE Falls perfectly around the base of the neck like a collar. On a petite woman it will hit your collarbone while for plus size women it might feel more like a choker.

18" (46 cm) NECKLACE A common choice for women that will fall just below the throat at the collarbone. This length is popular for adding pendants which will hang over a crew neck.

20" (51 cm) NECKLACE Will fall a few inches below the collarbone and allow a little more breathing room. Perfect for a low, plunging neckline or if you want to wear it over a turtleneck.

22" (56 cm) NECKLACE Falls at or above a low neckline.

24" (61 cm) NECKLACE Falls below any neckline.

30" (76 cm) NECKLACE Common with pearl strands and will hang below the bosom. They can be worn as a single strand or you can double them for an 18 inch necklace.
