Necklace length is easiest to choose when you stop thinking in labels such as “short” or “long” and start with one practical question: where do you want the necklace to sit? A difference of only a few centimeters can move a chain from close to the base of the neck to the collarbone or lower on the chest, and an extender can turn one necklace into several useful positions.
This guide compares common necklace lengths in both inches and centimeters, explains how to measure for your own fit, and maps the exact lengths currently documented across Valesstra’s Necklaces collection.
Necklace length chart: inches and centimeters
Jewelry brands commonly use a set of reference lengths, but the names attached to those lengths are not perfectly standardized. Use the numbers first and the placement descriptions as a visual starting point rather than a guarantee.
| Length | Approx. centimeters | Typical visual position |
|---|---|---|
| 14 in | 35.6 cm | Close around the neck |
| 16 in | 40.6 cm | Near the base of the neck / upper collarbone area |
| 18 in | 45.7 cm | Around the collarbone or just below |
| 20 in | 50.8 cm | Upper chest |
| 22 in | 55.9 cm | Lower on the upper chest |
| 24 in | 61.0 cm | Mid-chest on many wearers |
Those positions are approximate. Neck circumference, shoulder width, torso proportions, pendant size and even the way a chain drapes can change where the same measured length appears on two people.
How necklace length is measured
For a simple chain, necklace length generally refers to the wearable length from one end of the chain to the other, including the clasped path around the neck. For a pendant necklace, the listed chain length usually describes the chain itself; the pendant then extends visually below that point.
This is why two necklaces with the same stated chain length can look different when worn. A larger pendant creates more vertical drop. A rigid or chunky link can sit differently from a fine flexible chain. A layered design may also have multiple connected drops rather than one single straight length.
How to measure a necklace you already own
- Unclasp the necklace and lay it flat without stretching or pulling the chain.
- Use a soft measuring tape or ruler to measure the wearable chain path from end to end.
- If it has an extender, measure both the shortest wearable position and the longest usable position.
- For a pendant, record the chain length separately from the pendant drop if you want to compare how low the finished piece will appear.
If you already own a necklace that lands exactly where you like, this is usually the most useful reference for shopping another piece.
How to estimate the right necklace length on your body
A soft tape measure, ribbon or piece of string can help you preview placement. Form a loose loop around your neck at the position where you want the chain to sit, then measure that loop flat. Do not pull it tight against your skin; the goal is to preview jewelry placement, not to measure a tight circumference.
Then compare that number with the product’s listed length and extender range. If your preferred position falls between two standard lengths, an adjustable chain can give you more flexibility.
There is no universal “best” necklace length. A 40 cm chain may sit higher or lower depending on the wearer, and the same is true for 45 cm, 50 cm or any other measurement.
38 cm, 40 cm and 45 cm: what is the difference?
These are especially relevant to Valesstra’s current assortment.
- 38 cm ≈ 15.0 in. This is a relatively short starting length and can create a close, upper-neckline placement depending on the wearer and construction.
- 40 cm ≈ 15.75 in. This sits close to the common 16-inch reference and often works as a shorter chain or first layer.
- 45 cm ≈ 17.72 in. This is close to the common 18-inch reference and generally creates more separation from the neck than a 40 cm chain.
A five-centimeter difference is about two inches, which is enough to create visible separation in a necklace stack. That is why a 40 cm and 45 cm combination can work naturally for layering when the individual pieces and pendants do not compete for the same space.
Current Valesstra necklace lengths
The table below uses the specifications currently documented on Valesstra product records. When a necklace has an extender or layered construction, we keep the wording aligned with that product’s specification rather than converting it into a different construction.
| Necklace | Documented length | Approx. inch reference |
|---|---|---|
| Layered Drop Necklace | 38 cm + 2.5 cm + 2.5 cm layers | 38 cm ≈ 15.0 in starting reference |
| Bar Drop Layered Necklace | 38 cm + 2 cm + 2 cm extension | 38 cm ≈ 15.0 in starting reference |
| Box Chain Necklace | 40 cm | ≈ 15.75 in |
| Singapore Chain Necklace | 40 cm + 5 cm extender | ≈ 15.75–17.72 in |
| Beaded Trio Necklace | 40 cm + 5 cm extender | ≈ 15.75–17.72 in |
| Oval Solitaire Pendant Necklace | 40 cm + 5 cm extender | ≈ 15.75–17.72 in |
| Pavé Curve Necklace | 40 cm + 6 cm extension | ≈ 15.75–18.11 in |
| Oval Link Chain Necklace | 45 cm | ≈ 17.72 in |
| Cross Pendant Necklace | 45 cm | ≈ 17.72 in |
| Two-Tone Pendant Necklace | 45 cm | ≈ 17.72 in |
| Textured Barrel Necklace | 45 cm | ≈ 17.72 in |
| Water Wave Chain Necklace | 45 cm | ≈ 17.72 in |
| Faceted Barrel Necklace | 45 cm | ≈ 17.72 in |
Exact product specifications should always be checked on the individual product page before purchase, especially as assortments evolve.
Why an extender matters
An extender gives one necklace more than one usable placement. A 40 cm chain with a 5 cm extender can move through positions up to approximately 45 cm when the full extender is used. A 40 cm necklace with a 6 cm extension can reach approximately 46 cm.
That flexibility is useful for three reasons:
- Fit: you can adjust where the necklace sits on your own neckline.
- Clothing: a small change in length can move a pendant above or below a neckline edge.
- Layering: the same piece can become the shorter or longer layer depending on what you pair with it.
For example, the Singapore Chain Necklace, Beaded Trio Necklace and Oval Solitaire Pendant Necklace are currently listed at 40 cm with 5 cm extenders. The Pavé Curve Necklace is listed at 40 cm with a 6 cm extension.
Chain length vs. pendant drop
When you are choosing a pendant necklace, chain length is only half of the visual equation. A 45 cm chain with a small pendant and a 45 cm chain with a long drop pendant will not end at the same visual point.
If precise placement matters, look at both the listed chain length and the pendant dimensions. Product photography on a model can also help, but remember that model anatomy will not exactly reproduce the fit on every wearer.
Choosing a necklace length for different necklines
Think in terms of contrast and clear space rather than rigid rules.
A shorter necklace can sit cleanly above many open necklines. A necklace around the collarbone can work as an everyday placement because it remains visible with many tops. A longer chain or pendant can create a stronger vertical line with deeper or simpler necklines.
The useful test is whether the necklace sits intentionally above, within or below the clothing neckline rather than landing directly on a busy edge. Because clothing cuts and body proportions vary, use this as styling guidance rather than a fixed formula.
What length should you choose for a pendant?
If the pendant is your focal point, start by deciding where you want that focal point to land. Then work backward to chain length. A small pendant can feel delicate at a shorter placement; a larger or more sculptural pendant may benefit from more open space around it.
Valesstra’s current Pendant Necklaces include both 40 cm + extender and 45 cm constructions, so the product specifications give you a practical way to compare placements before buying.
What length should you choose for a plain chain?
A chain without a pendant is more about line, texture and how much of the neckline you want to frame. A fine 40 cm chain can create a shorter, quieter line. A 45 cm chain gives more drop. Link size matters too: an elongated or more substantial link can look visually bolder even when the measured length is the same.
Browse the current Chain Necklaces collection to compare fine, twisted, water-wave and oval-link constructions.
Using necklace length to build layers
Length creates the structure of a necklace stack. The easiest starting point is to make sure adjacent necklaces do not sit directly on top of one another. In Valesstra’s current assortment, a shorter 40 cm position and a 45 cm position can create a clean two-layer framework.
Then use texture and focal point to make the stack feel intentional. A fine chain can sit above a pendant, or two contrasting chain textures can be separated by length. If you want the full styling method, see How to Layer Necklaces.
How to convert necklace centimeters to inches
One inch equals 2.54 centimeters. To convert centimeters to inches, divide the centimeter measurement by 2.54. To convert inches to centimeters, multiply by 2.54.
Useful jewelry approximations include:
- 38 cm ≈ 15.0 in
- 40 cm ≈ 15.75 in
- 45 cm ≈ 17.72 in
- 50 cm ≈ 19.69 in
- 55 cm ≈ 21.65 in
- 60 cm ≈ 23.62 in
For shopping, it is usually better to preserve the brand’s stated measurement and treat the converted figure as an approximation.
Necklace length FAQs
What is the most common necklace length?
There is no single universal standard, but 16-inch and 18-inch lengths—roughly 40.6 cm and 45.7 cm—are common reference points in jewelry sizing guides. The best length still depends on the wearer, the chain and the design.
Is 40 cm the same as 16 inches?
Not exactly. Forty centimeters is approximately 15.75 inches. A true 16 inches is approximately 40.64 cm.
Is 45 cm the same as 18 inches?
They are close but not identical. Forty-five centimeters is approximately 17.72 inches, while 18 inches is approximately 45.72 cm.
How much difference does a 5 cm extender make?
Five centimeters is approximately 1.97 inches. On a 40 cm chain, using the full extender can bring the total wearable length to approximately 45 cm.
Does the pendant count in necklace length?
The listed chain length usually refers to the chain rather than the full vertical drop created by the pendant. Always check the product specifications because construction and measurement conventions can vary by design.
Can two necklaces with the same length fit differently?
Yes. Chain thickness, link structure, pendant weight and dimensions, and the wearer’s proportions can all affect how the same stated length appears.
The takeaway
Choose necklace length by placement first, number second. Decide where you want the necklace to sit, measure a favorite piece or preview the position with a soft tape, then compare that target with the exact product length and extender range.
For Valesstra, the current necklace assortment is concentrated around versatile shorter-to-collarbone placements: designs beginning around 38 cm, fixed 40 cm and 45 cm chains, and adjustable 40 cm styles with 5–6 cm extensions. Shop all Necklaces, or compare Chains and Pendants separately.
