Ring Sizing - How to get it right
Finding the Perfect Ring Size with Mandi & Co
At Mandi & Co, we believe that a ring should fit as perfectly as it complements your style — comfortable, secure, and effortlessly elegant. Getting your ring size right ensures that your jewellery not only looks beautiful but feels amazing every day.
How to Measure Your Ring Size
Here are some simple, reliable methods to find your perfect fit:
1. Use a Ring You Already Own
-
Measure the inner diameter of a ring that fits comfortably.
-
Use a ruler or caliper for accuracy in millimeters.
-
Compare it to our size chart below to find your corresponding ring size.
2. String or Paper Method
-
Wrap a piece of string or a strip of paper around the base of your finger.
-
Mark where it overlaps, then measure the length in millimeters.
-
Match this measurement to the circumference column in our size chart.
3. Professional Sizing
-
Visit a jeweller for a precise measurement, especially for engagement or bespoke rings.
-
This ensures comfort and allows for any adjustments for wider bands.
Tips for an Accurate Fit
-
Measure your finger at the end of the day — fingers swell slightly throughout the day.
-
Consider the width of the ring: wider bands may require a slightly larger size.
-
Don’t measure over knuckles that feel larger than the base of your finger; the ring should slide on comfortably but not too loosely.
