How to Measure Your Necklace Size

If you’re unsure what length will work best, measuring your ideal necklace length is simple. Here are two methods:

Using a Measuring Tape

Wrap a soft measuring tape around your neck where you want the necklace to fall.
Record the measurement in inches or centimeters.
Compare the number with the standard size chart above.

Using a String and Ruler

Cut a piece of string and wrap it around your neck to your desired length.
Lay it flat and measure it with a ruler.
Match the measurement to the chart for the closest size.

Tip for gifting: The 18-inch “Princess” length is the most universally flattering and suits most women.

How to Choose the Right Necklace Length

The right necklace length depends on more than just measurement. Consider your neckline, face shape, body type, and personal style to select the ideal size.

Matching Necklace with Neckline

Neckline Type	Recommended Necklace Length
V-neck	Princess or Pendant Necklace
Crew neck	Collar or Short Choker
Off-shoulder	Choker or Statement Necklace
Turtleneck	Matinee or Opera Length
Strapless	Short Necklace or Layered Styles

Choosing by Face Shape

Round Face: Avoid chokers. Opt for longer lengths that create a vertical line.
Oval Face: Almost all necklace lengths are flattering.
Heart-Shaped Face: Balance a broader forehead with collar-length necklaces.
Long Face: Short necklaces like chokers help add softness.

Choosing by Height and Body Type

Petite Height (Under 5’4″): Stick to shorter lengths like 16 to 20 inches.
Taller Women (Over 5’7″): Medium to long styles, like 20 to 30 inches, add balance.
Fuller Bust: Avoid necklaces that sit directly on the bust. Try matinee or opera lengths.
Small Bust: Shorter lengths can add the appearance of volume.

Styling Tips for Different Necklace Lengths

Layering different necklace lengths is a trend that allows you to express your personal style. Here’s how to create a stylish layered look:

Combine a choker (14″) with a princess-length chain (18″) and an opera-length necklace (30″).
Mix and match textures—such as a delicate gold chain with a chunky gemstone piece.
Use varied pendant sizes to create focal points at each length.
Stick to a consistent metal tone for a cohesive appearance.
