The most common choice for slimmer wrists. Sits close without gripping.

How to measure your wrist

  1. Wrap a soft tape measure around your wrist just below the wrist bone, where the bracelet will actually sit.
  2. Bring the ends together so it is snug but not tight. You should be able to slide a fingertip underneath.
  3. Read the measurement in millimetres. If you are using paper, mark where the ends meet and lay it flat against a ruler.
  4. Choose S/M for 130 to 170 mm, or M/L for 170 to 210 mm.

No tape measure?

A strip of paper, a phone charging cable or a shoelace all work. Wrap it, pinch where it meets, then measure the length against any ruler. A standard bank card is 85 mm along its long edge if you have nothing else to hand.

How it should feel

The bracelet should stay on your wrist without gripping it. You want to be able to turn it around your wrist with one finger, but not pull it over your hand without a bit of effort.

Getting this right also makes it last longer. A bracelet worn too tight keeps the elastic under permanent tension, which is the main thing that shortens the life of any stretch bracelet.
