inSync design Ring Size Guide

inSync design rings
When shopping for rings online, we want to make sure the ring you select will fit you perfectly!
The inSync rings are come in various widths ranging between 20-35mm that change as they undulate along the drawn line.
They should NOT be measured similarly to a wedding band as they have a wider grip on the finger. We therefore recommend selecting one size larger than you normally would with a thin band.

STEP BY STEP GUIDE TO MEASURE YOUR FINGER

Determine your ring size by using our ring size chart and helpful tips below.

You will need a piece of string, a marker and a measuring tape or a ruler. We recommend measuring your finger size several times to eliminate errors. 

  1. Cut a piece of string long enough to wrap around your finger.
  2. Wrap it around the base of your finger (make sure it’s at the widest part of your finger) and ensure it’s a snug and a comfortable fit.
  3. Mark where the end of the string overlaps.
  4. Lay the string flat against a ruler/ measuring tape and measure the length in millimetres.
  5. Use the Ring Size Conversion Chart below to find your correct ring size.

MEASURE A RING YOU ALREADY OWN

Alternatively, you can use a ring that you already own by using a ruler/ measuring tape to determine the diameter of the inside of the ring, then find the corresponding ring size below.

HELPFUL TIPS

  1. Your dominant hand is generally slightly larger - ensure you measure the finger the ring will be worn on most, on the correct hand!
  2. The inSync rings are wider than a standard band - they should NOT be measured similarly to a wedding band as they have a wider grip on the finger. We therefore recommend selecting one size larger than you normally would with a thin band.
  3. Make sure the finger is at a normal body temperature – fingers can expand or shrink when hot, cold or damp.
  4. Your fingers tend to change size throughout the day – the best time to measure your finger is towards the end of the day (when at its largest).
  5. If the ring size is between two sizes, we recommend sizing up – just to be safe!
