How to choose a necklace length
Measure the body part, then add ease
Necklace length is measured from clasp to clasp with the chain laid flat. Length determines where the necklace falls on the body, not how tight it is around the neck.
Standard length names
Standard names: collar 12–13″, choker 14–16″, princess 17–19″ (the everyday default), matinee 20–24″, opera 28–35″, rope 36″+. Add 1–2″ if you wear thicker collars or scarves underneath.
Sister sizing for in-between measurements
If your measurement falls between two sizes, the safer pick is usually the longer one — an extra link or 1/2″ of slack can be hidden by the clasp position, but a too-tight piece either won't close or wears the chain at the same friction points and breaks earlier. Look for adjustable extender chains (typically 1–2″) when the measurement is borderline.
Common mistakes
- Measuring the wrong reference point (necklace lengths are measured from clasp to clasp; bracelet lengths include the clasp).
- Confusing US and EU sizing — cm and inches are not interchangeable on the same chart.
- Forgetting that pendants and charms add visible length to a chain.
- Buying for the "perfect" fit on day one. Slight ease is what keeps the piece comfortable as the body shifts during the day.
