Necklace length comes down to where you want the piece to rest:
- 16” (≈40 cm) sits right at the base of the neck / collarbone.
- 18” (≈45 cm) sits just below the collarbone — the most popular everyday length.
- 20” and up (≈50 cm and up) falls toward the top of the neckline and layers easily over shorter chains.
For layering, leave about 2–3 inches between chains so they sit cleanly and don’t tangle.
