When should I measure my finger?

Before measuring the finger on which you will wear your custom-made ring, please ensure the following:
1. Do not measure a finger when it is cold or too hot as this can have a significant effect on a ring size. For example, when your fingers are cold they can be at least half a size smaller.
2. For an accurate reading, measure your finger at the end of the day, when it is larger.

Choosing the correct size

Your ring should fit your finger comfortably. It should be snug enough so that it won't fall off, but loose enough to slide over your knuckle. Do not forget that there are significant differences between the right and left hand. It's also worth bearing in mind that rings with a particularly thick band will feel tighter than a thin band; in these cases, we recommend buying a full size larger than your normal ring size. Please make sure your order the correct size.

Hesitating between two sizes?

If you are hesitating between two sizes, we tend to recommend that you choose the larger.

 

Buying the ring as a gift?

If you are buying the ring as a gift, ask a close friend or family member if they know the correct size or have a ring that fits perfectly that can be measured.
