Simple tools to find your ring, bangle and chain size at home. Still unsure? We'll help you get it right.
Choose the way that suits you. Our rings come in Australian sizes G to Z+6.
Hold a standard bank card upright against the screen and drag until the outline matches its width. Recalibrate after changing browser zoom or screen orientation.
Place your ring on the circle and drag until the circle matches the inside edge.
Between two sizes? Choose the larger one. Wider rings fit more snugly, so go up half a size for bands wider than 6mm.

A bangle has to slide over your hand, so we size by your hand, not your wrist.
A good fit slides over your hand comfortably and leaves room for one or two fingers at the wrist.
Wrist size alone cannot confirm the size of a solid bangle. It must slide over your hand comfortably.
| Size | Bangle diameter | Hand circumference (approx.) |
|---|---|---|
| XX-Small | 56mm | 175mm |
| X-Small | 59mm | 185mm |
| Small | 62mm | 195mm |
| Medium | 65mm | 205mm |
| Large | 68mm | 212mm |
| X-Large | 71mm | 225mm |
| XX-Large | 74mm | 235mm |
It's all about where you want it to sit. Tap a length to see it.

Absolutely. Every Kaikoa ring is covered by our Size Guarantee. As long as your ring hasn’t been worn and is returned to us in its original condition, we’ll happily swap it for the right size. We just ask that you cover the postage both ways.
Usually, yes. Wider bands tend to feel a little snugger on the finger, so for rings wider than 6mm, we generally recommend going up half a size.
Our bangles come in seven sizes, from XX-Small (56mm) to XX-Large (74mm) inside diameter. Each product page shows the size and width.
It really comes down to where you’d like your pendant to sit. Our chain guide shows each length and where it generally falls, so you can find the one that feels right for you. Go shorter for a closer fit, or longer for layering.
