There are several options for finding your ring size which we have presented below

Please scroll down for instructions on how to measure an existing ring or to measure your finger

The Basics

The engagement ring sits on the fourth finger (next to the little finger) of the left hand.

The average women’s ring size is US size 7 and the average men’s ring size is US size 10.

  Woman Man
Slim / Petite Size 6 Size 9
Average Size 7 Size 10
Above average Size 9 Size 12


Rings with wider bands will fit a bit tighter, you should bear this in mind especially when you are purchasing a ring for someone else

If you are selecting a band that is over 5mm wide, you should consider going up by a half-size for comfort


If your knuckle is bigger, take 2 measurements and choose a size in between

Your ring needs to be able to slide over your knuckle but it should not be too loose or it will shift around


The best time to measure is in the evening when your fingers are at their largest

Make sure your fingers are at normal body temperature. Cold fingers can shrink up to half a size

Avoid measuring your fingers after consuming alcohol or salty foods as they can make your fingers swell


We only carry full sizes at Azarai

If your finger measures as a half-size, go up in size for comfort

We offer resizing services for all rings purchased from us. As an alternative you can also use a ring guard or ring snuggie if your ring is slightly oversized


If you are purchasing a ring for someone else, always go up in size if you are not sure

It is better for the ring to be too big than too small

We offer free exchanges for size within 7 calendar days subject to availability
