Using a String Method:

• Take a piece of string or soft measuring tape.
• Drape it around your neck at the desired length, letting it hang naturally where you want the necklace to sit.
• Mark the point where the string meets.
• Lay the string flat and measure the length with a ruler.

Using an Existing Necklace:

• If you already own a necklace that fits perfectly, simply lay it flat and measure from end to end (including the clasp) with a ruler or measuring tape.
