* Linjer uses US ring sizes, but please note that ring sizes may vary slightly between brands. It's best to confirm against actual ring/finger measurements.
How to quickly find your Linjer ring size
Method 1: Measure the inside diameter of a ring you already own

Check the table above to find your ring size.
Method 2: Measure the circumference of your finger
- Measure your finger by wrapping around it snugly with measuring tape. If you don't have measuring tape, you can use string/floss or even paper, and measure against a ruler
- Make sure your fingers are at a normal size when you measure them. Fingers shrink a bit in cold weather, and they swell after you've had alcohol, after you've exercised, when you're in hot weather, and when you're generally bloated
- If your knuckle is particularly big, you may want to choose a bigger ring size so that the ring can fit over the knuckle
Check the table above in the "Finger Circumference (mm)" column to find your ring size.
Method 3: Use a Linjer ring size measurement tool
- Order a free ring size measurement tool from Linjer. (You may need to pay a nominal amount for shipping if you are not purchasing other items.) This ring sizer is designed specifically to help you determine your Linjer ring size.
