Standard Necklace Lengths

Each standard necklace length creates a distinct visual effect and pairs best with certain outfits and necklines.

14-Inch Necklace 

14-inch necklaces sit snugly around the neck like a choker. This length makes a bold statement and draws attention to the neck and face. 14-inch necklaces pair beautifully with off-shoulder styles, boat necks, and V-necks, creating a striking contrast that frames the neck area. 

 

16-Inch Necklace 

At 16 inches, this versatile length rests at the base of the throat, making it an excellent choice for highlighting the collarbones. This length works wonderfully with open necklines and adds a refined accent to business attire. 

 

18-Inch Necklace 

The 18-inch length is the most common and universally flattering necklace length. It sits perfectly at the collarbone, making it ideal for pendant necklaces and everyday wear. This versatile length complements virtually any outfit or neckline, making it a staple in most jewelry collections.

20-22 Inch Necklace 

20-22 inch necklaces fall below the collarbone, creating a sophisticated look that works well with both casual and formal attire. This length is particularly flattering with higher necklines and business wear, as it adds visual interest without competing with the neckline. 

 

24-Inch Necklace 

The 24-inch length reaches the top of the bust, creating an elongating effect. This length works excellently for statement pieces and pendant necklaces, balancing well with both casual and professional outfits. It's also a popular length for men's chains, particularly for pendants. 

 

30-36 Inch Necklace 

30-36 inch necklaces rest at mid-chest or below, creating dramatic elegance. These longer strands can be worn as single dramatic pieces or doubled to create layered looks. They're particularly striking with evening wear, high necklines, and minimalist outfits.

How to Measure Necklace Length

Accurate measurements are important for ensuring your necklace sits exactly where you want it. Here are two reliable methods for determining the perfect length: 

 

Method 1: Using an Existing Necklace

If you already own a necklace that sits at your preferred length: 


  1. Lay the necklace flat on a level surface, ensuring it's straight with no kinks. 
  2. Use a ruler or measuring tape to measure from end to end, including the clasp. 

 

Method 2: Using String or Measuring Tape 

For a personalized fit:


  1. Wrap a flexible measuring tape or piece of string around your neck, positioning it where you want the necklace to rest. 
  2. For choker styles, measure snugly but comfortably at the base of the neck. 
  3. For longer styles, hold the string/tape where you'd like the necklace to fall. 
  4. Mark or pinch the point where the ends meet. 
  5. Lay the string/tape flat against a ruler to determine the length. 
  6. Add 1-2 inches (2.5-5 cm) to allow for movement and the weight of any pendant. 

 

Measuring with Pendants in Mind

When selecting a chain for a pendant: 


  1. Measure as described above to determine your preferred chain length. 
  2. Consider the pendant's size—larger pendants typically need longer chains. 
  3. Add the pendant's length (including bail) to understand the total drop length. 
  4. For pendants with significant weight, choose a slightly shorter chain than you might otherwise, as the weight will cause the necklace to hang lower.

How to Choose Necklace Length

Selecting the ideal necklace length involves considering several key factors beyond personal preference.

Outfit and Neckline 

Different necklace lengths harmonize with specific clothing styles:


  • Turtlenecks pair beautifully with 30-36" lengths or longer pendants. 
  • V-necks harmonize with 18" lengths that echo the neckline's shape. 
  • Crew necks work well with shorter (16") or much longer (30"+) necklaces. 
  • Boat necks complement choker styles (14-16") that create a striking contrast. 
  • Off-shoulder styles shine with collar-length necklaces (14") that highlight the neck and shoulders. 
  • Strapless outfits pair elegantly with 18-24" lengths.

Layering Considerations 

When planning to layer multiple necklaces:


  • Choose varying lengths with at least 2-4 inches difference between each piece. 
  • The most popular layering combination involves 16", 18", and 20" necklaces worn together. 
  • Consider necklace weight and bulk—pair delicate chains with heavier statement pieces for balance. 
  • Mix metals and textures thoughtfully for a curated rather than cluttered appearance.

Necklace Length FAQ

How do you layer necklaces that are the same length?

When layering necklaces of the same length, you have several options:


  1. Use necklace extenders on one or more pieces to create graduated lengths. 
  2. Select chains of varying thickness or texture to create visual differentiation. 
  3. Add a pendant to one necklace to create a focal point at a different height.

Does necklace length include the clasp?

Yes, standard necklace length measurements include the clasp. When manufacturers list a necklace as 18 inches, this measurement refers to the total end-to-end length including the clasp mechanism. This is particularly important to remember when measuring existing necklaces as reference points—always include the clasp in your measurement to ensure accurate sizing when purchasing new pieces.

How can you extend a necklace's length?

Several effective methods exist for extending necklace length:


  1. Necklace extenders: These attachable chain segments typically add 2-6 inches and are available in various metals to match your jewelry. 
  2. Jump rings: Adding additional jump rings to the clasp area can provide extra length in small increments. 
  3. Chain extensions: A jeweler can permanently add additional chain links to increase length. 
  4. Converter clasps: These specialized clasps incorporate additional chain length that can be used or tucked away as needed. 
  5. Chain connectors: For significant length increases, two necklaces can be connected using special linking components.

How can you shorten a necklace's length?

To reduce a necklace's length without professional assistance:


  1. Use the jump rings often included along the back chain of adjustable necklaces. 
  2. Create a temporary shortening by tying a small knot in a chain necklace (ideal for rope lengths). 
  3. Loop longer necklaces multiple times around the neck for a layered effect.


For permanent solutions:


  1. Consult a professional jeweler who can remove links or sections of chain. 
  2. Have additional clasp options installed at different points along the chain. 
  3. For pearl or beaded necklaces, a jeweler can restring the piece to the desired length.
