Ring Sizing Chart

How to determine your ring size  

All our Tungsten Carbide rings are comfort fit style, which means there is a slight dome on the inside of the ring, resulting in a very comfortable fitting ring. Our precious metal rings are made to order. Comfort fit rings are great for men because it's easier to squeeze over large knuckles, making them an ease putting on and taking off.

The most accurate way to determine your ring size is to head to your local jeweller and ask them to measure your finger. Please inform the jeweller the approximate width of your ring as wider bands require a larger size and also advise them that they are comfort fit rings. If possible try a ring of the same width and comfort fit style. The ideal size will fit comfortably and be tight enough to prevent the ring from accidentally falling off. Not too tight, not too loose. Your  finger size will change with temperature, activity and time of day. The best time to measure accurately is at the end of the day when your fingers are warm. We recommend checking your size more than once. Check your size on a cold day and again on a warmer day. Checking two or three times is not going too far because getting it right the first time could save you time, frustration and money. 

If you already own a ring you can measure the inner circumference or inner diameter and compare it to our chart below.
