The following are important tips to consider when measuring ring sizes.

TEMPERATURE IS IMPORTANT

Finger size changes often as a result of the temperature. Fingers get bigger in warm weather and shrink in cold weather. Measure your finger in warm temperatures at the end of the day, as the finger will be at its largest during this time.

MEASURE RING SIZE MORE THAN ONCE

The ring should fit snugly on your finger. It should slide smoothly when you ease it onto your finger, but it shouldn’t come off easily. That’s what makes a ring properly sized as it minimizes the risk of loss and it won’t put too much pressure on your fingers. Checking your size more than once will help you achieve this.

Don’t think that measuring ring sizes several times is too extreme. Measuring repeatedly can help you get the right fit for the first time. It will also prevent you from spending unnecessary time, money, and energy to resize the ring.

CONSIDER THE RING TYPE

Wide rings (about 6 millimetres or more) require a larger size for most people. This is because a wide band allows more space under the band for the finger than narrow rings do. Add an allowance of 0.25 to 0.5 size for rings with wider styles.

For instance, if your ring size is 6 after measuring, make it 6.25 or 6.5 if you are going for the wider band. Furthermore, some rings are difficult to resize or are often impossible to size without a loss in the aesthetic. So it’s important to get the size right for those types of rings.

FINGERS ARE DIFFERENT

Generally speaking, one of your hands is slightly larger (about half a size) than the other. This hand is usually your dominant hand. To avoid any errors, it is important that you measure the left hand or whatever finger you plan to wear the ring on.

ACCOUNT FOR YOUR KNUCKLE’S SIZE

If the base of your finger is a lot smaller than your finger knuckle is and you’re using the virtual ruler, measure both the base of your finger and your knuckle, and select a size in between the two.

That will help you choose a size that will allow the ring to slide over your knuckle but won’t be too large to be comfortably worn on the base of your finger.

GO FOR THE LARGER SIZE

When two sizes seem to fit or if you get two different finger measurements, it’s advisable you go for the bigger measurement or consult a professional if you can.

To better measure ring sizes, take your measurements in millimetres.
