Find your ring size

Every ring we make is true to size in US measurements. If you usually shop in UK, European, Japanese or another system, here's exactly what to order — and how to measure at home in two minutes.

i.

The size converter

Tell us your size in your own system, or a measurement you've taken, and we'll show you the US size to select at checkout — plus every international equivalent.

Your size, in your own system
Your measurement in millimetres

Wrap a strip of paper around your finger, or measure across the inside of a ring you own. Not sure how? See "Measure at home" just below.

Measure at home

No ring sizer needed. Either method takes a couple of minutes — measure the same finger and hand you'll actually wear the ring on.

Most accurate

Measure a ring you own

  1. Pick a ring that already fits the right finger.
  2. Measure straight across the inside of the band, edge to edge, in millimetres — that's the inside diameter.
  3. Switch the converter to “I measured it”, choose Diameter, and enter the number.

Once you have a measurement, pop it into "I measured it" in the converter above and we'll show your US size.

No ring needed

Measure your finger

  1. Cut a thin strip of paper or take a length of string.
  2. Wrap it snugly around the base of your finger and mark where it overlaps.
  3. Lay it flat, measure the length in millimetres, then enter it as the Circumference above.

Measure at the end of the day when fingers are largest, and not when your hands are cold — both make a real difference.

iii.

Full conversion chart

Find your size in any column and read across. The millimetre measurements are the true size — every label is the closest standard match to them.

US / Canada UK / AU EU / ISO Japan Inside ⌀ (mm) Circumference (mm)

UK & Australia share the same letters; Ireland and New Zealand use them too. EU / ISO numbers are the inside circumference in millimetres. Where a row falls between two sizes in another system, we've rounded to the nearest.

iv.

Getting the fit right

A ring should slide over the knuckle with a little resistance and sit comfortably at the base — a slight pause coming off, never a struggle.

◇ Between two sizes?

Choose the larger one. A ring that's slightly loose is far easier to live with — and to resize — than one that's too tight.

◇ Wide or stacked bands

Anything wider than about 6 mm, plus eternity and stacking styles, usually needs a half size up — there's less room for the finger.

◇ Larger knuckle

If your knuckle is wider than the base of your finger, measure both and pick a size in between, so the ring clears the knuckle but won't spin.

◇ Time & temperature

Fingers swell across the day and in the heat, and shrink in the cold. Measure warm and late for the most reliable result.

Printable ring sizer

Print this page at 100% / Actual size — do not select “Shrink” or “Fit to page”. Check the result by holding a bank card against the dashed box: it should measure exactly 85.6 mm wide. Then lay a ring you own over each circle and find the one that matches the inside of the band.

Hold a bank card here — 85.6 mm × 53.98 mm

Every discomarshmallow ring is cut and set to order, in US sizing.

Sizing a surprise, or still caught between two? Send us your finger's circumference in millimetres before you order and we'll confirm the size with you.
