How to Measure Your Neck for a Necklace
Finding the perfect necklace fit can elevate your style and comfort, whether you’re selecting a casual piece or a special day collar. Here’s a step-by-step guide to accurately measure your neck so your necklace sits exactly where you want it.
1. Gather What You Need
To measure your neck, you’ll need:
- A soft, flexible measuring tape (fabric tape works best)
- A mirror (optional, but helpful for seeing the fit)
- A string and ruler if you don’t have a measuring tape
2. Find Your Neck Measurement
- Wrap the measuring tape snugly around your neck, right at the base. This is typically right above your collarbone. Make sure the tape sits comfortably, without pulling too tight.
- Record the measurement where the tape meets. This number is your neck’s circumference.
If you’re using a string:
- Wrap the string around your neck in the same spot.
- Mark where the end meets.
- Lay the string flat against a ruler to measure the length.
3. Add Length for Desired Necklace Fit
Use your neck measurement as a starting point, then add length to determine where you’d like the necklace to sit:
- Choker Fit: Add 1-2 inches to your neck measurement for a close, comfortable fit.
- Standard Collar Fit: For day collars and discreet pieces, add about 2-3 inches to your neck measurement.
- Pendant or Lariat Style: Adding 3-5 inches or more will create a looser, longer style that falls at your collarbone or lower.
