DETERMINING YOUR RING SIZE

We recommend visiting your closest JDC store to have your finger size measured by one of our friendly Sales Consultants. Should you not have a JDC store nearby, you can visit another jeweller and ask them to measure your finger size. Should neither of these be possible, you can use the helpful information below to determine the finger size.

How to measure your finger

Your ring should fit your finger comfortably; it needs to sit snug enough so it will not fall off, but it needs to be loose enough to slide over your knuckle.

Finger size changes depending on the time of day and the weather. For the best result measure your finger size:

• For the best accuracy, measure your finger when your hands are warm as well as when they are cold. (Fingers are generally smaller in the morning and larger in the afternoon.)
• Measure you finger size 3 to 4 times to eliminate the possibility of a incorrect measurement.

Tips for buying a ring as a surprise

Ask your significant other’s mother or friends if they know her ring finger size.

You can also borrow one of your significant other’s rings that she wears on her ring finger and take it to your closest jeweller and ask them to measure the ring for you.

If you are in the possession of a vernier you can measure the inside diamater of the ring and use the chart below to find the finger size.

How to personally measure a ring size

Please use the steps listed below to find a ring size. Should you measure and a finger size comes in at the bottom of this chart, but your significant other has dainty hands, or vice versa. Please check your measurements again, as the lower the size is on the chart, the bigger the finger size is.

What you will need:

1. a scissor
2. a ruler (work with the mm side)
3. a pen or pencil

Steps for measuring your finger

1. Cut a thin strip of paper. (It should have a width of about 6mm.)
2. Wrap the paper around the finger of the person that you wish to purchase the ring for (as tightly as possible.) Make sure the paper is below the joint of the finger and close to your knuckle. Mark the spot where the paper meets. (For the best accuracy; ensure that the paper does not bend or tear and that it stays straight.)
3. Use the chart below to determine your ring size. Start by lining up the start of the paper with 0 on the ruler. Keeping the piece of paper straight the mark will line up with another number on the ruler. Use this measurement and the circumference on the chart below to determine the finger size that you need.
