To help you find the perfect fit, we have created this necklace length guide, covering how to measure necklace length, where different styles sit, and how to choose the right fit for any occasion.

Whether you're layering or selecting a single piece, knowing your ideal necklace length makes all the difference. Let’s jump right in!

Necklace length chart (CM guide)

Here’s a simple necklace length chart showing where common lengths sit:

Length (cm)	Name	Where It Falls	Best For
35-40 cm	Choker	Sits tightly around the neck	High necklines, strapless dresses, layering with longer pieces, minimalist looks
45 cm	Princess length	At the collarbone	Everyday wear, pendants, most necklines (most versatile option)
50-60 cm	Matinee	Below the collarbone	Office wear, layering, adding length without going too long
60-70 cm	Opera length	On the chest	Statement looks, high necklines, elongating the torso
75+ cm	Rope length	Below the chest	Layering, bold styling, wrapping multiple times for versatility

If you're wondering where different length necklaces fall, this guide helps you visualise how each length works with your outfit.

How to measure necklace length

Method 1: Measure an existing necklace

Lay the necklace flat
Measure from end to end (including the clasp)
This gives you the total necklace chain length

Method 2: Use a string or tape

Wrap it around your neck at your desired length
Mark where it meets
Measure it with a ruler

This is the easiest way to understand how you measure the length of a necklace before buying.

How are necklace lengths measured?

The standard way necklace lengths are measured is the full chain length, from clasp to clasp. This means:

A 45 cm necklace measures 45 cm end-to-end
The drop will vary depending on your neck size and body proportions

Understanding this helps you better interpret any necklace length guide when shopping online.

How to choose a necklace length

Of course, choosing the right length depends on your style, outfit and proportions.

1. Consider your neckline

High necklines → Longer chains (50 cm+)
V-necks → Pendant styles around 45–55 cm
Strapless → Chokers or shorter lengths

2. Think about layering

Layering works best when combining different necklace lengths:

40 cm + 45 cm + 50 cm creates depth
Mix textures and pendant sizes for balance

3. Match your proportions

Shorter lengths highlight the neckline
Longer lengths elongate the torso

If you’re deciding how to choose necklace length, start with a 45 cm piece and build from there.

Necklace lengths in CM vs Inches

Jewellery measurements may be listed in either centimetres or inches, depending on the retailer or region. To make things easier, here are some of the most common necklace lengths in both cm and inches:

40 cm ≈ 16 inches
45 cm ≈ 18 inches
50 cm ≈ 20 inches
60 cm ≈ 24 inches

This helps when comparing international sizing in any necklace length chart.

Finding your perfect necklace length

The best necklace length ultimately depends on how you wear your jewellery.

A shorter chain feels classic and refined, while longer styles add drama and versatility. If you’re building a collection, having a mix of lengths gives you more styling flexibility.

You can explore different styles through the GS Diamonds jewellery collection or browse dedicated necklace designs in the necklaces collection.

If you’re still unsure, trying different lengths in person can quickly show what suits you best.
