How to Measure Necklace Length

How do you know what necklace length (or lengths) to focus on when you’re shopping for a chain, a strand of pearls, or a pendant? A necklace that hits at your collarbone, just below, or even longer can accentuate your best features—and elevate whatever you happen to be wearing. 

The goal is to choose a necklace length that is in proportion to your neck size; a necklace that is too tight, or swings too long, can be cumbersome—and potentially quite uncomfortable. And that discomfort could mean that a new necklace sits in your jewelry box, unworn for eternity. 

Ahead, we’ll show you how to measure your ideal necklace length at home and share a guide on the variety of lengths. In other words, you can use this guide to navigate the long and short of it—and everything in between.


What Are the Most Common Necklace Lengths?

Before you start measuring necklace lengths, let’s review the standard necklace lengths you are likely to encounter and where they are most likely to fall on a person’s body.

It might be helpful to keep in mind that 18 inches is considered the most popular necklace length for women, as close to universally flattering as it gets. As for men, the most common necklace length is 20 inches, ideally hitting at or around the collarbone area.  

Meanwhile, longer necklace lengths (22 inches and longer) are great on their own but perfect for layering with other necklace styles.


Necklace Length Guide

Women’s necklaces come in even-inch chain lengths ranging from 14 to 36 inches. Whether you fancy a snug choker, a simple solitaire pendant on a delicate chain, or a long, swingy sautoir that can be doubled up, there’s no shortage of options to choose from. Below, you’ll find a breakdown of necklace lengths and how they fit.

How to Measure Necklace Length at Home

Now that you’re more familiar with the standard necklace lengths available, you’re ready to determine the necklace length that is going to look best. Here are three simple methods to try at home. 


Measure the length of a necklace you already own

Let’s say you already own a necklace but don’t know what length it is. But you do know that you like where it falls. When shopping for a new necklace, you can use the existing necklace’s length as a guide. To measure:

  1. Unhook the clasp of your necklace and lay it on a flat surface.  
  2. Tug each end of the chain to make sure it’s fully outstretched and straight.  
  3. Use a tape measurer or yardstick to measure the entire chain— including the clasp. 
  4. Note the length in inches; round up to the next inch if you get a measurement that isn’t a precise number.  
  5. Add a new necklace to the cart accordingly!


Create a mock necklace using a tape measurer or piece of string

  1. Wrap a soft tape measure (i.e., the one that’s like a ribbon) or piece of string around your neck as if you were putting on a necklace (it’s helpful to stand in front of the mirror while doing this).
  2. Adjust it to your desired length. 
  3. Keep your finger on the spot where the two points meet. 
  4. Unwrap the tape or string while keeping your finger on the mark. 
  5. Note the length; if you’re using string, measure the length of the string using a ruler or tape measure.  


Measure the circumference of the base of your neck

  1. Wrap a soft tape measure around the base of your neck. 
  2. Note the inch mark where the long end intersects.
  3. Adjust to any of the standard necklace lengths for a visual on how they will look; slide on one of your existing pendants, or a ring if you don’t have one handy, to further assess how short or long you want to go.

When you find the perfect necklace, make sure it’s protected by obtaining personal jewelry insurance through Jewelers Mutual. It’s an affordable option that covers loss, damage, and disappearances. You can check your rate by clicking the button below.
