How to Choose the Right Necklace Length

As a jeweller, I’m often asked: what’s the ideal necklace length? It’s a great question, but not one with a single answer. The right length depends on the style of necklace, whether it features a charm or pendant, and the wearer’s proportions, age, and personal preferences.

If you’re choosing a necklace as a gift, getting the length right can turn a beautiful present into a cherished piece they’ll reach for every day. Here’s a guide to help you feel confident in selecting the perfect chain length from the start.

Popular Necklace Lengths Explained

In my experience, these are the most commonly chosen chain lengths:

• 16” Chain – Sits close to the base of the neck on most adults. Perfect for smaller charms or minimalist pendants.
• 18” Chain – Falls at the collarbone. A versatile, everyday length that works with most necklines.
• 20” Chain – Hangs just below the collarbone. Great for layering or wearing over jumpers with larger charms or pendants.

Keep in mind that these are based on standard adult proportions—height, frame, and personal style can all influence what feels comfortable and looks best.

Choosing the Right Length: Real-Life Examples

To make this decision easier, here are a few real-world examples from my work as a jeweller:

1. A Necklace for a Tall Teenager

For a 13-year-old who’s tall for her age, a 16” chain is usually ideal. But if she’s especially tall, consider an 18” chain with a discreet extra link at 16”. This gives her the flexibility to wear it shorter now and adjust as she grows. Many jewellers can add an extra ring for a nominal fee.

2. A 50th Birthday Gift for a Petite, Curvy Woman

If she loves bold necklaces worn over jumpers, an 18” chain might be a safe classic. But for added comfort and impact, a 20” chain could be the better choice—especially when worn over high-neck knitwear. Measuring one of her favourite necklaces can also help guide your decision.

3. A Necklace for a Tall, Athletic Man in His 20s

For a man over 6 feet tall with a broad frame, consider a 20” or 22” chain. If he likes pendants, a 24” chain will allow it to sit mid-chest. Slightly thicker chains often look better at these lengths, giving a balanced, masculine finish.

4. For Younger Girls Who Want a Pendant Necklace

A 16” chain is generally suitable for girls aged 10 to 12. Adding a 14” link allows them to wear it shorter when they’re younger, then extend it as they grow—an ideal option for a piece they can treasure over time.

Necklace Lengths Styled by Figure Skaters

1) 14” Chain: A short, delicate fit that sits high on the neck — perfect for younger skaters or a subtle look.

2) 16” and 18” Chains: This skater wears two necklaces for a classic layered look that highlights the neckline.

3) 22” Chain: Worn by a male skater, this longer chain sits comfortably on the chest, offering a relaxed, confident style.

4) 16” and 20” Chains: A layered style with a more dramatic length contrast, worn by a skater for a modern, elegant look.

The Benefit of Personalisation

One of the joys of buying from a local or independent jeweller is the ability to personalise the fit. Whether it’s shortening a chain, lengthening it slightly, or adding an extra link for flexibility, most jewellers are happy to help for a small fee. This small adjustment can make a big difference in comfort and wearability.

When in doubt, speak to a jeweller. A professional can help you make sure the necklace you choose will be not only beautiful, but also a perfect fit.
