How to Choose the Right Ring Size?
Finding the perfect ring size is key to comfort — whether you’re choosing an engagement ring, a meaningful gift, or everyday jewellery. A well-fitted ring not only looks beautiful, but also feels great to wear.
The Most Accurate Way: Visit a Jeweller
The most precise option is to visit a local jeweller, who can measure your finger or an existing ring using the standard European ring sizing system. This is the best method — especially if you’re buying an engagement ring or a gift for someone special.
How to Measure Your Ring Size at Home
Can’t visit a jeweller? No problem — here are two simple methods you can try at home:
1. String or a thin strip of paper
– Wrap it around your finger where the ring will sit
– Mark the spot where the ends meet and measure the length in millimetres
– Compare the result with our ring size chart
2. Do you already have a ring that fits?
– Measure the inner diameter of the ring using a ruler or caliper
– Match the measurement to the corresponding size on our chart
For accuracy, measure your finger twice – once in the morning and once in the evening – as finger size can vary with temperature and time of day.

Extra Tips When Choosing a Ring Size
The style of the ring matters:
For thin bands (like our Meteorite Ring), choose a snug fit.
For wider bands (like the Wave Ring with amber) or Double Rings, you may want to go slightly up in size.

How to Choose the Right Ring Size as a Gift
Planning a surprise? Here are a few ways to guess someone’s ring size without spoiling it:
Measure a ring they already wear — ideally one worn on the same finger.
Ask someone close — a sister, mum or friend might know the size.
Use the guide below for general size ranges by finger and hand type (sizes are in the Polish system, where size = circumference in mm):
Finger | Slim Hand | Medium Hand | Wider Hand |
---|---|---|---|
Ring finger | 8–11 | 12–15 | 15–18 |
Middle finger | 10–13 | 13–17 | 17–20 |
Index finger | 11–14 | 16–20 | 17–21 |
Little finger | 5–7 | 6–9 | 8–10 |
(These are approximate ranges and may vary depending on hand proportions.)
