Ring Size Chart

Sizing

Janai Jewellery realises that you may not know the ring size for a given finger, and we want to help. We provide a printable ring sizer that can help you determine your ring size. Prior to printing, ensure that page scaling is set to "none" on your print dialog box.


Measuring Your Finger

Your ring should fit your finger comfortably enough so that it will not fall off, but loose enough to slide over your knuckle.

Finger size changes depending on the time of day and the weather, here are some tips to ensure the best results for determining your size:

  • At the end of the day and when your fingers are warm (fingers are smaller in the early morning and when cold).
  • Measure finger size 3 to 4 times to eliminate an erroneous reading.

Avoid using string or paper to measure ring size as these materials can stretch or twist, yielding an inaccurate measurement.


A Word About Ring Sizes

Please be aware that the ring sizes shown on Janai Jewellery Store reflect ring sizes used in the UK sizing. To find your ring size, measure your finger and then use the International Ring Size Chart to convert your size to the corresponding UK size. That is the size you should order.


Tips for Buying the Ring as a Surprise

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

Borrow his/her ring (from the correct finger) and use the ring measurements below to determine the rightful size.
