METHOD 1: MEASURING THE DIAMETER
Use Your Current Ring
Measure a metal ring that you already own and fits properly on the exact same finger as the one for your new ring.
Put this ring onto a ruler and measure the inside centre line (diameter) in millimetres.
Find Size on Chart
Now find the size for your diameter measurement on the International conversion chart below.
METHOD 2: MEASURING THE CIRCUMFERENCE
Wrap Piece of Paper
Cut a piece of string (preferably not stretchy) or a strip of paper (plus-minus 8mm wide x 120mm in length). Wrap the paper very tight around the ring finger.
Mark Overlapping Papper
Use pen to mark the paper where it completes the circle and the two ends meet.
Find Size On Chart
Use the International conversion chart below to find your corresponding ring size in the circumference table.
RING SIZE CHART
MEASURING YOUR RING SIZE
1. Decide on which finger you are going to wear the ring. The fingers on your dominant hand is normally larger than those of the other hand.
2. Cold weather tends to cause your fingers to shrink a bit.
3. High temperatures and other factors like water retention, injuries, etc. can cause swelling of the finger. Measure your finger in warm temperatures at the end of the day.
4. Keep the size of your knuckle in mind.
5. The perfect fit will mean that the ring will feel comfortable most of the time, but not always. Sometimes it might feel a bit loose and sometimes a bit tight - all depending on the weather, what you eat, whether you work with your hands a lot or whether you have some underlying medical conditions. It should fit snug without leaving marks or bulging. or having to use soap or oil to take it off.
HARD OR METAL RINGS
Correct fit: the ring should slide over the knuckle easily (with just a little bit of friction) to fit snugly, comfortably on the base of the finger. (Not too tight). In removing the ring you should use a little extra force and feel a bit of resistance.
Should a ring size chart indicate that your measurement falls between two numbers - we recommend that you order the smaller size.
Silicone rings relax after a few days of wear. If you order the bigger number, you may find that your ring is too loose after a couple of days.
Tight Not Uncomfortable
The smaller ring may feel a little tight(not uncomfortably or painfully) at the beginning but will soon relax to the perfect fit.
If your knuckle is a lot larger than the base of your finger, you need to measure both the base of your finger and your knuckle, then select a size between the two. These rings stretch to pass the knuckle and need to fit snugly, yet comfortably on the base of the finger. No half sizes in silicone, you need to take the smaller size, eg: you need size 10.5 you will take size 10.
