How to size wedding bands

Measure the body part, then add ease

Wedding bands use the same finger size as engagement rings, but band width is a separate decision. A wider band feels tighter on the same finger size; if you're between sizes, go up a quarter size for bands wider than 6 mm.

Standard length names

Common band widths: 2 mm dainty, 3–4 mm standard women's, 5–6 mm standard men's, 7–8 mm wide, 8 mm+ very wide. Profile (flat, comfort-fit, beveled) also affects perceived fit on the finger.

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.
