What You’ll Need to Measure

Before you begin, gather:

• A piece of thread, string, or thin ribbon

• A ruler or measuring tape

• A mirror (optional, for checking placement)

Step-by-Step: How to Measure Necklace or Bracelet Size

1. Wrap the String

• For necklaces: Loop the string around your neck to where you'd like the pendant or chain to sit—collarbone, chest, or longer.

• For bracelets: Wrap around your wrist where you'd like the bracelet to rest—snug or slightly loose.

2. Mark the Length

• Pinch or cut the string at the exact point where both ends meet.

• This marks your ideal jewelry length.

3. Measure the String

• Lay it flat against a ruler or tape measure.

• Write down the measurement in inches—this is the size to order.

Pro Tip: If you're between sizes, go up half an inch for comfort.
