Size Guide

Find Your Perfect Ring Size

At Nila Noor, we use the European standard for ring sizes, which is measured by the inner circumference in millimeters. For example, a size 50 ring has an inner circumference of 50 mm. Please note that since our rings are handcrafted, slight variations may occur. Finding the right ring size can be challenging, so we have created this guide to help you measure at home. However, for the most accurate sizing, we always recommend visiting a jeweler to have your finger professionally measured.

How to Measure Your Ring Size at Home

Option 1: Measure Your Finger
• Prepare your materials – You will need a thin strip of paper, a ruler, scissors, and a pen.
• Wrap the paper around your finger – Place the strip around the finger where you want to wear the ring. It should fit snugly but comfortably.
• Mark the overlap – Use a pen to mark the point where the paper overlaps.
• Measure the length – Lay the paper flat and use a ruler to measure the distance between the two marks in millimeters.
• Find your size – Compare your measurement with the size chart below to determine your ring size. 

If your measurement falls between two sizes, we recommend choosing the larger size for a more comfortable fit.

Option 2: Measure an Existing Ring
• Find a ring that fits the intended finger perfectly.
• Measure the inner diameter – Use a ruler or caliper to measure the inside width of the ring, from edge to edge in millimeters.
• Find your size – Compare your measurement with the size chart below to determine the corresponding ring size.
