Necklace Size Guide
Find your perfect length
At Isabel Carter, every piece is designed to celebrate individuality. The right necklace length frames your story beautifully — whether you prefer a subtle choker, an everyday classic, or a longer layer for stacking.
Standard Necklace Lengths
-
40cm (16") – Sits just above the collarbone. A delicate, close-to-the-neck look that layers effortlessly with longer chains.
-
45cm (18") – The classic everyday length and the most popular length. Designed to fall just below the collarbone, flattering for both solo wear and stacking.
-
50cm (20") – A longer length, perfect for creating a relaxed drape or layering with shorter chains.
Necklace Extenders
All Isabel Carter necklaces include a 5cm extender, giving you the flexibility to adjust your fit and create beautifully personalised stacks.
