Summarize the article with:
Choosing the right necklace length can completely change how a piece looks when you wear it. A chain that sits beautifully at the collarbone can create a very different effect from one that falls lower on the chest. The right choice also depends on your neckline, pendant size, personal style, and whether you plan to wear the necklace alone or as part of a layered look.
For Canadian jewelry shoppers, necklace lengths are commonly listed in both inches and centimetres. Standard options often include 16, 18, 20, 22, 24, 30, and 36 inches, although availability varies by design and jeweller. Tiffany & Co. Canada, for example, lists 16-, 18-, 20-, 24-, 30-, and 36-inch necklace lengths and recommends using a piece of string to visualize where each length will sit.
At Ryan Jewellers, finding the right proportions is part of choosing jewelry that feels personal and effortless. Explore our fine jewelry collection while using this guide to understand which necklace length may work best for your wardrobe and lifestyle.
Understanding Common Necklace Lengths
Necklace length is measured from one end of the necklace to the other, including the clasp. While the exact position can vary according to neck circumference, body proportions, chain thickness, and pendant size, standard lengths provide a useful starting point.
14–16 Inches: Choker and Short Necklace
Necklaces around 14 to 16 inches sit relatively close to the neck.
They can work well for:
- Open necklines
- Strapless styles
- Layered looks
- Minimalist jewelry
A 16-inch necklace generally sits around the base of the neck or near the collarbone, although the exact position depends on the wearer.
18 Inches: Classic Everyday Length
An 18-inch necklace is one of the most versatile options for everyday jewelry.
It generally sits around the collarbone or slightly below it, depending on the wearer’s neck and body proportions.
This length works well for:
- Pendant necklaces
- Diamond necklaces
- Everyday chains
- Casual outfits
- Formal clothing
Canadian retailers commonly offer 18-inch necklaces as a standard option, making it a useful starting point when you are unsure which length to choose.
20–24 Inches: Longer Everyday and Statement Styles
A 20- to 24-inch necklace generally falls lower on the chest.
These lengths can be useful when you want:
- A more relaxed appearance
- A larger pendant
- More visual separation from the neckline
- Additional layering options
A 24-inch necklace will generally fall lower than a 20-inch necklace, although the exact position varies between individuals.
30–36 Inches: Long and Statement Necklaces
Necklaces measuring 30 inches or longer create a more dramatic appearance.
They can work particularly well with:
- High necklines
- Evening outfits
- Long pendants
- Statement jewelry
- Layered arrangements
Tiffany’s Canadian size guide includes 30- and 36-inch options as longer necklace lengths.
Necklace Length Chart
| Length | Approx. Metric | Typical Position | Common Use |
|---|---|---|---|
| 14–16 in | 36–41 cm | Close to neck | Choker, layering |
| 18 in | 46 cm | Around collarbone | Everyday, pendants |
| 20 in | 51 cm | Below collarbone | Versatile styling |
| 22 in | 56 cm | Upper chest | Pendants, layering |
| 24 in | 61 cm | Lower chest | Statement styles |
| 30 in | 76 cm | Chest/lower chest | Long necklaces |
| 36 in | 91 cm | Lower chest | Dramatic or layered looks |
These positions are approximate rather than fixed measurements because neck circumference, body proportions, and pendant dimensions affect how a necklace sits.

Necklace Lengths for Different Necklines
Your clothing neckline is one of the easiest ways to determine which necklace length will complement an outfit.
V-Neck Necklines
V-neck tops and dresses naturally create a central opening.
A necklace that follows or complements this shape can work particularly well.
Consider:
- 16–18 inches for a shorter look
- 18–22 inches for pendant styles
- Longer necklaces for a more dramatic effect
A pendant with a pointed or elongated design can also echo the shape of a V-neck.
Crew Necklines
Crew necks sit relatively high around the base of the neck.
Short necklaces can create a clean appearance, while longer necklaces provide contrast.
Consider:
- 16–18 inches for minimal jewelry
- 20–24 inches for more visual separation
- Long necklaces for statement styling
High Necklines and Turtlenecks
Longer necklaces often provide stronger contrast against high-neck clothing.
Consider:
- 20–24 inches
- 30 inches
- 36 inches for statement looks
The additional length helps create a vertical line over the fabric.
Strapless and Off-the-Shoulder Necklines
These necklines leave more of the upper chest and shoulders visible.
Shorter necklaces can emphasize the neckline, while longer designs create a more dramatic drop.
Good starting points include:
- 14–16 inches
- 18 inches
- Longer pendant necklaces
Button-Down Shirts
A button-down shirt offers considerable flexibility.
An 18-inch necklace can work with the collar open, while longer necklaces can create a more relaxed appearance over the shirt.
How to Choose a Necklace Length for Your Style
There is no single necklace length that works for everyone. Your preferred look should play a major role in the decision.
For Minimalist Jewelry
If you prefer understated jewelry, shorter lengths such as 16 or 18 inches can create a clean and refined appearance.
A simple chain or small pendant can add detail without dominating the outfit.
For Classic Fine Jewelry
An 18-inch necklace is a versatile option for many classic designs.
It can work with:
- Diamond pendants
- Gold chains
- Pearl-inspired styles
- Everyday fine jewelry
For Statement Jewelry
If you want your necklace to become a focal point, consider a longer chain or a larger pendant.
Lengths around 20 to 24 inches can provide additional space for a statement pendant.
Consider Your Pendant Size
The chain length is only part of the equation.
A large pendant adds additional drop below the chain, meaning the finished necklace will visually extend farther down the chest.
For example, an 18-inch chain with a substantial pendant will not appear the same as an 18-inch chain worn without a pendant.
Tiffany also notes that the size of the pendant and circumference of the neck affect how a necklace sits.
Consider Your Neck Circumference
If you have a larger or smaller neck circumference, the same necklace length may sit differently.
This is particularly important for shorter necklace styles.
Rather than relying solely on a standard chart, visualize the necklace on your own body before purchasing.

Best Necklace Lengths for Layering
Layering works best when each necklace has enough separation to remain visually distinct.
Wearing multiple necklaces at nearly identical lengths can cause them to overlap, tangle, or hide one another.
Start With a Shorter Necklace
A 16- or 18-inch necklace can work as the foundation of a layered look.
It provides a relatively high starting point around the neck or collarbone.
Add a Medium-Length Necklace
A second necklace around 20–22 inches creates additional separation.
You can vary:
- Chain style
- Pendant size
- Texture
- Metal colour
Finish With a Longer Necklace
A 24-inch or longer necklace can create the lowest visual layer.
For more dramatic styling, 30- or 36-inch necklaces can add significant length.
How Much Space Should You Leave Between Layers?
There is no strict universal spacing rule because chain thickness and pendant size change the final appearance. However, choosing noticeably different lengths makes each necklace easier to see.
A simple combination might be:
- 16 inches
- 18 inches
- 22 inches
For a more pronounced layered effect:
- 18 inches
- 22 inches
- 24–30 inches
Different lengths help create the tiered appearance recommended in professional necklace sizing guides.
Choosing Necklace Lengths for Different Occasions
The right necklace length can also depend on where you plan to wear it.
Everyday Wear
For everyday jewelry, versatility is usually the priority.
An 18-inch necklace can work well with many casual and professional outfits, while 20–22 inches can provide a slightly more relaxed appearance.
Office and Professional Outfits
For professional clothing, consider necklace lengths that complement the neckline without competing with the outfit.
Shorter chains and moderate-length pendants can work particularly well with:
- Blouses
- Button-down shirts
- Dresses
- Blazers
Weddings and Formal Events
Formal occasions provide more room for statement jewelry.
Depending on the neckline, you might consider:
- Short diamond necklaces
- Classic 18-inch pendants
- Longer statement pieces
The necklace should complement the neckline rather than compete with it.
Gifting
If you are purchasing a necklace as a gift and do not know the recipient’s preferred length, versatility becomes especially important.
An 18-inch necklace is a common standard, while a necklace with an extender can offer additional flexibility.
However, the recipient’s existing jewelry can provide an even better indication of their preferred length.
Bridal Jewelry
For bridal styling, necklace length should be coordinated with:
- Wedding dress neckline
- Earrings
- Pendant size
- Hairstyle
- Overall jewelry design
A shorter necklace may complement a strapless or sweetheart neckline, while a longer necklace can work with higher or more structured necklines.

How to Measure the Necklace Length You Need
You do not necessarily need a necklace sizing tool to visualize different lengths.
Use a Piece of String
Tiffany’s Canadian size guide recommends cutting a piece of string to the same length as the necklace you are considering and placing it around your neck to see where it falls.
You can test several lengths this way.
For example:
- Cut string to 16 inches
- Place it around your neck
- Mark where it falls
- Repeat with 18, 20, or 24 inches
- Compare the positions
This gives you a much better idea of the finished look than relying on numbers alone.
Measure a Necklace You Already Own
If you already have a necklace that fits exactly how you like:
- Lay it flat
- Fully extend the chain
- Measure its total length
- Record the measurement
- Use it as your reference when shopping
This is particularly useful when ordering jewelry online.
FAQ About Necklace Lengths
What is the most common necklace length?
18 inches is a widely available and versatile necklace length, particularly for everyday necklaces and pendants. However, popularity varies by retailer, customer preferences, and jewelry type.
Is an 18-inch necklace too short?
Not necessarily. An 18-inch necklace commonly sits around the collarbone, although the exact position depends on your neck circumference and body proportions.
What necklace length is best for a pendant?
An 18- to 22-inch necklace can work well for many pendants. However, pendant size and the wearer’s neck circumference should also be considered.
What necklace length is best for layering?
There is no single required length combination. Using noticeably different lengths, such as 16, 18, and 22 inches, can help create visible separation between layers.
How do I know what necklace length will fit me?
Measure your neck or use a string cut to your preferred necklace length. You can also measure a necklace you already own and like.
Does body type affect necklace length?
Yes. Neck circumference, torso length, height, and overall proportions can influence where the same necklace length sits. Therefore, standard charts should be treated as starting points rather than exact rules.
What necklace length should I choose as a gift?
If you do not know the recipient’s preferred size, an 18-inch necklace is a versatile starting point. However, checking their existing jewelry or choosing a design with an extender can provide greater flexibility.
Can the same necklace length look different on different people?
Yes. Two people wearing the same necklace can have different results because neck circumference, body proportions, pendant size, and chain thickness affect the final position.
Final Thoughts
Choosing the right necklace length is about finding the balance between comfort, neckline, proportion, and personal style. While standard measurements such as 16, 18, 20, 22, and 24 inches provide useful starting points, the same length will not look identical on everyone.
Before purchasing, consider where you want the necklace to sit, what clothing you will wear it with, whether it includes a pendant, and whether you plan to layer it with other pieces.
