How to Measure Your Ring Size
When measuring your ring size, keep a few things in mind:
-
Fingers Size may change throughout the year
Finger size can vary due to temperature or physical activity.
-
Avoid Cold Hands
Don’t measure your size when your hands are cold — your fingers can be up to half a size smaller.
-
Consider Band Width
Wider bands feel tighter than thinner rings. For wider styles, we recommend going one size up for comfort.
-
Comfort is Key
Your ring should fit snugly but comfortably. It should be secure enough not to slip off but still able to slide over your knuckle when removing it.
-
Use apps
Already have a ring that fits you well and want another one in the same size? Use a Ring Sizer app (or similar) to measure the inner diameter of your ring. Make sure you got it precise, even half of a millimetre makes a difference
Still Unsure?
The most accurate way to find your size is by visiting a local jeweller and asking to measure your fingers with a ring sizer.
