Serotonin Necklace
Necklace Length Guide
Choosing the right necklace length can make all the difference to how your jewellery sits and feels. Our visual guide shows the four most popular lengths on an average neckline so you can easily see where each one falls:
-
14" – Choker Length
Sits closely around the base of the neck. Perfect for a snug, elegant fit or for layering with longer pieces. -
16" – Classic Short Necklace
Falls just below the collarbone on most people. A timeless everyday length and ideal for small pendants. -
18" – Standard Pendant Length
Rests on the upper chest. This is our most popular and versatile length for gifting, flattering most necklines. -
20" – Longer, Relaxed Length
Sits a little lower on the chest for an effortlessly elegant look. Great for creating a layered style or adding extra movement.
Tip: Everyone’s proportions are a little different. If you're choosing a gift, 18" is the safest all-round option—beautiful on its own and easy to layer with other pieces.
