Choosing the right size necklace to pair with your neckline can be tricky, we get it; if you're unsure about which length to go for, we've created a simple guide including a size chart and easy instructions for measuring, to make finding the perfect fit a whole lot easier.
Standard Necklace Lengths
Necklaces are sold in standard lengths typically ranging from 14 to 40 inches and the clasp is generally not included in the measurement. Below are the most common sizes, their fit, and the necklines they pair well with.
Length | Fit | Neckline |
Choker: 16 inches | Base of the neck | Almost all necklines especially off the shoulder, crew, and boat necklines. |
Princess: 18 inches | On the collarbone | This is the most popular length and works with all necklines. |
Matinee: 20+ inches | Below the collarbone | Works best with collared shirts and high necklines. |
Opera: 28+ inches | Below the bust | High necklines like turtle and boat necks suit this length best. |
Rope: 40+ inches | Over the navel | This draping length is worn best with high necklines, scooped collars, and formal wear. |

How To Measure Your Ideal Necklace Length
The most accurate way to measure your ideal necklace length is to measure a perfectly fitting necklace you already own. Alternatively, stand in front of a mirror and use a soft tape measure to work out your ideal length. Measure yourself with different clothing so you know how each of the standard necklace sizes will work with your style. Different outfits = different necklace lengths.
Necklace lengths and their fit can vary depending on your size and shape. Longer necklaces will fall in an elongated V-shape while shorter necklaces will provide a gentle curve in the chain. Knowing your body shape, your clothing style, and how you want your jewellery to fall when worn will help you find the ideal length.
