How to Measure Your Neck for a Necklace
How to measure your neck for a necklace is easiest when you separate two questions: your actual neck circumference and where you want the necklace to sit. A flexible tape gives you the first number; the second depends on chain length, pendant size, body shape, neckline and personal preference.
Do not assume that a standard necklace length will fall in exactly the same place on every person. The same 45 cm chain can sit close to the collarbone on one wearer and lower on another because neck circumference and upper-body proportions differ.
Step 1: measure the neck circumference
- Stand naturally and keep your shoulders relaxed.
- Place a soft measuring tape around the base of the neck where a close necklace would sit.
- Keep the tape level and comfortably in contact with the skin without pulling it tight.
- Read the measurement in centimetres.
- Repeat once to check that you get the same result.
Step 2: decide where you want the necklace to finish
Your neck measurement is not automatically the necklace length you should buy. For most pendant and everyday styles, you need additional length so the chain sits below the neck rather than fitting closely around it.
One practical method is to take a piece of string or ribbon, adjust it until it sits where you want the necklace to fall, then measure the full length of that string. This gives you a personal target length rather than relying only on generic charts.
Common necklace lengths in context
Common chain lengths such as 40 cm, 45 cm, 50 cm and 60 cm are useful reference points, but their exact position varies by wearer. A 40 cm chain often sits relatively high; 45 cm is a widely used everyday length; 50 cm gives more drop; longer chains create a lower focal point.
| Approximate chain length | Typical visual effect |
|---|---|
| 40 cm | Close to the base of the neck on many wearers |
| 45 cm | Classic short necklace or pendant position |
| 50 cm | Lower pendant position and more breathing room |
| 60 cm+ | Longer line, often worn over clothing |
Remember that a pendant adds visual length
A 45 cm necklace with a 30 mm pendant does not look the same as a plain 45 cm chain. The chain length tells you where the suspension point sits; the pendant continues below it. Check pendant height separately when you are trying to match a neckline.
Extension chains change the usable range
If a necklace is listed as 45 cm + 5 cm extension, it can usually be fastened at different points within that range depending on the chain construction. This is useful when you want one pendant to work with several necklines.
How clothing changes the ideal length
- Open shirt: a pendant can sit inside the open collar or lower over the fabric.
- Crew neck: a slightly longer chain can prevent the pendant from colliding with the neckline edge.
- V-neck: a pendant often looks balanced when it follows the same general downward line.
- High neck: longer necklaces worn over the fabric can create a cleaner vertical line.
- Strapless: shorter necklaces can work well because the neckline leaves open space above the dress.
Do not use model photographs as a measuring tool
Model images are helpful for scale and styling, but they cannot predict exactly where a necklace will sit on you. Always read the stated chain length and pendant dimensions, then compare those numbers with your own measurement.
A practical at-home test
If you are deciding between two lengths, cut two pieces of ribbon or string to the exact measurements, add the pendant drop if relevant, and try them with the clothes you expect to wear. This gives a more realistic answer than looking at an abstract chart.

Frequently Asked Questions
Should necklace length equal neck circumference?
Usually not for an ordinary pendant necklace. Your neck circumference is the starting measurement; extra length is needed to create the desired drop.
How do I choose between 40 cm and 45 cm?
Use string cut to both lengths and compare how each sits with your neck circumference and favourite necklines.
Does pendant size count in necklace length?
The chain length and pendant drop are separate measurements. A pendant extends below the point where the chain reaches its lowest position.
What if I already own a necklace that fits perfectly?
Lay it flat and measure it end to end, including the clasp. That measurement is an excellent personal reference for future purchases.
