Necklace Size Guide – Find the Right Necklace Length in cm or inches

Choosing the right necklace length can make a big difference to how your jewellery looks and feels. This necklace size guide helps you compare popular chain lengths in both inches and centimetres, so you can choose the best fit for chokers, pendants, layering necklaces and everyday jewellery.

Necklace lengths sit differently depending on body shape, neckline and personal style, but this guide gives a helpful general idea of where each size usually falls.

Common Necklace Lengths

13 inch / 33 cm – A short choker-style necklace that sits closely around the neck. Ideal for bold, fashionable looks and layered jewellery.

16 inch / 40.6 cm – A classic collarbone length. Perfect for short chains, delicate necklaces and everyday wear.

18 inch / 45.7 cm – One of the most popular necklace sizes. Often called princess length, it works very well with pendants and simple chain necklaces.

20 inch / 50.8 cm – Falls slightly below the collarbone, giving a more relaxed everyday look.

22 inch / 55.9 cm – A flattering mid-length necklace, ideal for open necklines, layering and slightly larger pendants.

24 inch / 61 cm – Sits around the upper chest and works beautifully with statement pendants and longer jewellery designs.

28 inch / 71.1 cm – A long necklace length, great for layering, relaxed styling and elegant fashion jewellery.

30 inch / 76.2 cm – An extra-long necklace size, ideal for dramatic looks, layering and statement chains.

35 inch / 88.9 cm – A very long necklace length that can be worn as a bold fashion piece or sometimes doubled up for a layered effect.

How to Choose the Best Necklace Length

For a close-fitting style, choose shorter necklace lengths such as 13 inch or 16 inch. For everyday jewellery and pendants, 18 inch and 20 inch necklaces are usually the most popular choices. Longer lengths such as 24 inch, 28 inch, 30 inch and 35 inch are ideal for statement pieces, layering and more relaxed styling.

When choosing a necklace, consider the neckline of your clothing, the size of the pendant, your body proportions and whether you want the jewellery to sit close to the neck or lower on the chest.
