Ring Size Guide
Find your perfect fit. The right ring should feel effortless — here's how to make sure yours does.
Method 1 — Measure Your Finger
All you need is a thin strip of paper, a pen, and a ruler.
- Cut a thin, narrow strip of paper — about 1cm wide and 10cm long
- Wrap it snugly around the finger you plan to wear your ring on
- Mark the point where the two ends meet
- Lay it flat and measure the length in millimetres — this is your circumference
- Match your measurement to the size chart below
💡 ZAVINA Tip: Fingers naturally swell throughout the day. For the most accurate fit, measure in the evening when your fingers are at their largest — and always measure the specific finger you'll be wearing your ring on.
Method 2 — Use a Ring You Already Own
Already have a ring that fits perfectly? This is the easiest method — and the best one if you're surprising someone special.
- Choose a ring that fits comfortably on the intended finger
- Measure the inner diameter (straight across the inside of the band) using a ruler
- Match your measurement in millimetres to the chart below
💡 ZAVINA Tip: If your measurement falls between two sizes, always size up. A ring that slips on easily is far more comfortable than one you have to wrestle off.

Still Not Sure?
If you're ordering as a gift or genuinely can't decide between two sizes, here's what we suggest:
- Go up, not down. A slightly looser ring is easier to resize than one that won't go past your knuckle.
- Check our refund policy — we want you to love your piece, and we're here to help if the fit isn't quite right.
- Contact us — our team is always happy to help you find your perfect size before you order.
At ZAVINA, we want every piece to feel like it was made for you — because in every way that matters, it was.
