How to Measure the Right Necklace Size
To find your perfect necklace size, simply wrap a soft tape measure around your neck.
Make sure it feels comfortable—not too tight or too loose.
Once you have your measurement, compare it to a necklace size chart to choose the best length.
The most common necklace sizes are 16” (41 cm), 18” (46 cm), 20” (51 cm), and 22” (56 cm).
Necklace Sizes
Finding the right necklace length is more than just measurements—style and material also affect how it looks and feels.
Below are the most popular necklace lengths and how they sit when worn:
14” – 16” (Choker Length)
A choker rests closely around the neck and highlights the neckline.
It’s a great option if you want a bold, modern look or prefer pendants that sit near the heart.
18” (Princess Length)
The 18-inch necklace is the most popular and universally flattering size.
It gently lays on the collarbone, making it perfect for everyday wear and showcasing charms or pendants.
20” (Matinee Length)
At 20 inches, the necklace falls just below the collarbone.
This length works well with both casual and professional outfits and can be styled alone or layered.
22” (Opera Length)
An elegant choice, the 22-inch necklace adds sophistication and drama.
It can be worn as a single long strand or doubled for a chic layered look, making it versatile for both formal events and everyday style.
