Between two sizes? Take the larger one. Our statement pieces sit wide on the finger, and a wide band always wears slightly tighter than a thin one.

Most sizes ship from stock. On a few pieces, some sizes are made to order and will show as pre-order when you select them.

Measure at home

Measure a ring you own

The most reliable method, if you have a ring that already fits the finger you're buying for.

  1. Lay the ring flat on a ruler with millimetres.
  2. Measure straight across the inside opening, edge to edge.
  3. Match that number to the inside diameter column above.

Measure your finger

Use a strip of paper about 5 mm wide, or a length of string.

  1. Wrap it around the base of the finger, snug but not tight.
  2. Mark where the strip overlaps, then lay it flat and measure to the mark.
  3. Match that number to the inside circumference column above.

Before you measure

  • Measure at the end of the day, when fingers are at their largest. Cold hands measure small.
  • Check the exact finger you'll wear it on — the dominant hand usually runs half a size bigger.
  • The ring has to pass the knuckle. If your knuckle is much wider than the base of the finger, size to the knuckle.
  • Printed sizers and phone apps drift with screen and paper scaling. Treat them as a starting point, not a final answer.

Still unsure? Write to us at hello@oakaash.com and we'll help you land on the right size.

Crafted with Purpose

From first sketch to final polish, each piece is made to outlast the season it launched in.
