How to measure Ring Size

 

If you want to know your size...

 

  • Remember that a product you want to measure should be round (it cannot be oval or crumpled).
  • If you buy a wide wedding ring (band width 9 - 10 mm), choose a half ring size bigger to be safe.   

 

If you want to buy a ring as a gift...

  • Ask the mother, sister or best friend of the person that the present is to be given to, if they find out the size of her ring.
  • Borrow one of her rings and check the size. (Make sure that the borrowed ring fits the finger that the purchased ring will be worn on).  

Measure Your Ring Size

 

I have already a model ring. How to measure the size? 

  • The best way to check the size is to show the model ring in 2-3 shops, and ask for the size measurement. If there are any differences discuss it with us. 
  • You can measure the inside diameter with a calliper. Measure in a few points and calculate the average (products are often bent and do not have an ideal inside diameter - because of that, taking measurement only in one place can not be precise)  

 

  Below, you will find a table. By using it, you can determine the size by measuring a model ring's inside diameter or circumference.
