Your finger size will expand and change throughout the day depending on the elements such as weather. It is a good idea to measure in the morning and again in the afternoon to determine the best size. The fit should be comfortable but not be able to slide off the finger too easily. Check your length against this chart.
Ring Size
Find your perfect fit for our Australian handcrafted jewellery. Your ring should feel comfortable for everyday wear. We recommend selecting a ring size that can be easily put on and taken off your finger.
How to Measure Your Ring Size
Method 1: Measure Your Finger
- Cut a strip of paper or use a piece of string
- Wrap it snugly around the base of your finger
- Mark where the ends overlap
- Measure the length (in mm)
- Match to the circumference column in our chart
Method 2: Measure a Ring You Own
- Take a ring that fits well
- Measure the inner diameter (in mm)
- Match to the diameter column in our chart
Important Tips:
- 📏 Measure at room temperature (fingers shrink when cold)
- ⏰ Measure at the end of the day (fingers swell slightly)
- 💍 For wide bands (4mm+), go up half a size
- 🖐 When in doubt between sizes, choose the larger one
