People Also Ask (FAQs)
Quick answers to the most common questions about necklace sizing and lengths.
How do I measure my necklace length?
There are two simple ways to measure. Method 1 (Body): Wrap a soft measuring tape or a piece of string around your neck where you want the necklace to sit, then measure the string against a ruler. Method 2 (Existing Jewelry): Take a necklace that already fits you perfectly, unclasp it, lay it completely flat on a table, and measure it from end to end using a standard ruler or measuring tape.
How long is a 12 inch necklace?
A 12-inch necklace is very short and is considered a tight collar. For an adult woman, this will usually wrap extremely tightly around the middle of the neck, and for many adults, it will not fit at all. A 12-inch chain is most commonly used for children's jewelry or very petite chokers.
How long is a 32 necklace?
A 32-inch necklace falls into the "Opera" length category. It is quite long and will drape elegantly below the bust, often resting on the lower torso. This length is highly versatile because you can wear it as a single long strand for a dramatic look, or loop it twice around your neck to create a layered choker and matinee effect.
How long is a 22 inch necklace?
A 22-inch necklace is a medium-long length. For a woman, it sits between the collarbone and the bust (in the Matinee category), making it excellent for wearing over higher necklines like turtlenecks or with larger pendants. For a man, a 22-inch chain will rest just below the collarbone, offering a comfortable, relaxed fit.
What is the right length for a necklace?
The "right" length depends entirely on your body type and the outfit you are wearing. However, the universal standard for women is 18 inches (resting on the collarbone), which flatters almost every neckline. The standard everyday length for men is 20 inches (resting right at the collarbone).
Is a 16 or 18 inch necklace better?
Both are excellent, but they serve different purposes. A 16-inch (Choker) is better for wrapping snugly around the base of the throat and looks great with scoop necks or off-the-shoulder tops. An 18-inch (Princess) is universally flattering, sits slightly lower on the collarbone, and is generally better if you want to add a small pendant.
Is a 20 inch necklace long?
For a woman, a 20-inch necklace is considered a "short Matinee" length. It's not exceedingly long, but it does drape nicely past the collarbone onto the upper chest. For a man, 20 inches is considered the standard, average starting length and is not categorized as long.
What is the most attractive necklace length?
Historically and stylistically, the 18-inch Princess length is considered the most attractive for women because it draws the eye directly to the collarbones, subtly framing the face without getting lost in the neckline of your clothing. For highlighting the décolletage, a 20-inch chain with a delicate pendant is also highly attractive.
Necklace Size Chart mm, cm, inches
Jewelry is an international industry. While buyers in the United States and the UK typically shop in inches, much of Europe, Asia, and international wholesale markets measure chains in centimeters (cm) and chain thickness in millimeters (mm).
To make your shopping experience seamless regardless of where you are buying from, here is our master conversion chart. Use this to quickly translate between the three most common measurement systems.
| Inches (in) | Centimeters (cm) | Millimeters (mm) | Common Style Name |
|---|---|---|---|
| 14" | 35 cm | 350 mm | Collar |
| 16" | 40 cm | 400 mm | Choker |
| 18" | 45 cm | 450 mm | Princess |
| 20" | 50 cm | 500 mm | Matinee (Short) |
| 22" | 55 cm | 550 mm | Matinee (Medium) |
| 24" | 60 cm | 600 mm | Matinee (Long) |
| 30" | 76 cm | 760 mm | Opera |
| 36" | 91 cm | 910 mm | Rope |
Necklace Size Chart for Women
When looking at a necklace size chart for women, you will notice that lengths are usually categorized by traditional names. These names—like Princess, Matinee, and Opera—have been used by jewelers for over a century to describe exactly where the jewelry will rest on the female body.
Here is a detailed breakdown of what each size means for a woman's wardrobe:
- 14-inch (Collar): This length sits very tightly around the base of the neck. It is a striking look best suited for V-necks, scoop necks, or off-the-shoulder tops. Because it offers no drape, it is usually worn without a pendant.
- 16-inch (Choker): Sits perfectly around the base of the throat. On a petite woman, this will fall right at the collarbone. It's a fantastic everyday length that peeks out beautifully from underneath a button-down shirt.
- 18-inch (Princess): The undisputed champion of women's jewelry. If you are buying a gift and have no idea what size to get, buy an 18-inch. It rests elegantly on the collarbone.
- 20-inch to 24-inch (Matinee): These lengths drape gracefully over the top of clothing. A 20-inch chain usually falls between the collarbone and the bust, making it the ideal choice for business and casual wear alike. The 24-inch length usually falls exactly at the center of the bust.
- 28-inch to 36-inch (Opera & Rope): These dramatic lengths sit below the bust and can even reach the navel. They are highly versatile—you can wear them as a single long, sweeping strand, or loop them twice around your neck to create a layered choker and matinee effect.
Average Necklace Length for a Woman
If you are looking for the absolute standard, the average necklace length for a woman is 18 inches (45 cm).
Why is this the industry standard? Because human anatomy dictates that for the average female frame, an 18-inch chain will rest just below the throat and directly on the collarbones. This is the most universally flattering placement. It allows pendants to sit flat against the chest rather than dangling awkwardly in the cleavage or choking the neck. When in doubt, start with 18 inches.
💡 Styling Tip Based on Body Type
If you have a petite frame (under 5'4"), a 16-inch chain might actually fit you exactly like an 18-inch chain fits an average-height woman. Conversely, if you have a fuller figure, a broader neck, or are quite tall, you might want to consider a 20-inch chain as your "everyday" comfortable length.
Gold Necklace Size Calculator
When you are investing in a precious metal like gold, precision matters. A gold necklace size calculator takes into account not just the length, but the way gold behaves as a material.
Gold chains—especially popular styles like Cuban links, Miami Cubans, or thick rope chains—are dense and heavy. A thick 18-inch gold Cuban link will actually fit tighter on your neck than a paper-thin 18-inch gold cable chain. This is because the thickness of the chain itself takes up internal circumference space.
How to use our tool for gold: If you are buying a thin gold chain (1mm to 3mm), use our calculator exactly as is. However, if you are purchasing a thick gold chain (5mm or thicker), we highly recommend taking the calculator's suggested length and going one size up to ensure it doesn't fit too snugly against your skin.
Silver Necklace Size Calculator in cm
Sterling silver is incredibly popular for larger, statement pendants and everyday bohemian styles. Using our silver necklace size calculator in cm is particularly useful because many premium silver artisans and designers are based in Europe (like Italy, famous for its 925 sterling silver chains).
When calculating silver lengths, keep in mind that silver can tarnish when exposed heavily to sweat and natural body oils. If you want a silver chain for everyday wear (especially in the summer), you might want to calculate a slightly longer length—such as 50 cm or 55 cm—so the chain rests on top of your clothing rather than directly against your skin all day. This simple trick drastically reduces how often you need to polish your silver jewelry.
Pearl Necklace Size Chart
Pearls are unique. Unlike metal chains, a strand of pearls consists of spherical gems individually knotted on a silk thread. Because pearls have volume (usually ranging from 6mm to 12mm thick), a pearl necklace will always sit higher and tighter on the neck than a metal chain of the exact same length.
| Pearl Style | Standard Length | Best Worn With |
|---|---|---|
| Pearl Collar | 12" - 13" | V-necks, boat necks, formal evening gowns. Sits directly against the throat. |
| Pearl Choker | 14" - 16" | Virtually everything. This is the classic "Jackie Kennedy" everyday pearl look. |
| Pearl Princess | 17" - 19" | High crew necklines or plunging necklines. Rests just over the collarbone. |
| Pearl Matinee | 20" - 24" | Business attire, suits, and dresses. Great for a sophisticated office look. |
| Pearl Opera | 26" - 36" | High necklines and turtlenecks. Adds immense drama and vertical length. |
Necklace Size Calculator in Inches
For most of our North American users, calculating in inches is second nature. Our necklace size calculator in inches works by taking your exact anatomical measurement and applying a mathematical formula based on standard jewelry manufacturing sizes.
Here is exactly how the math behind our calculator works if you want to do it yourself:
- Find your base: Measure your neck comfortably. Let's say it is 14.5 inches.
- For a Choker: Add exactly 2 inches. (14.5 + 2 = 16.5). You would round down to a 16" or up to an 18" depending on comfort.
- For a Standard Fit: Add 3 to 4 inches. (14.5 + 3.5 = 18). An 18-inch chain is your perfect standard fit.
- For Pendants: Always add at least 4 inches so the V-shape created by the pendant's weight has enough room to drape without pulling uncomfortably on the back of your neck.
