Tip: When your fingers are cold (because of the weather), they will become thinner than usual. So, when you try a ring on when your fingers are cold, the ring may seem a bit loose. The best time to try a ring on, or to measure your finger for the ring, is therefore when your fingers are not cold.
You can also go to any jewellery store and ask to have your finger sized.
The size chart below is estimated only. The actual sizes may vary depending on different ring styles, materials, etc.
