How to size earrings
Measure the body part, then add ease
Earring size is the visible dimension hanging from the lobe. Stud size is measured by stone or front diameter; hoop size is the outer diameter; drop size is the total length from the ear hook.
Standard length names
Common ranges: studs 2–8 mm, small hoops 10–20 mm, medium hoops 25–40 mm, large hoops 50–70 mm, drops 30–80 mm. Heavier earrings need lobe-protecting backings or large flat-back posts.
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.
