Accurate Ring Sizing Guide
Use a proper ring sizer or visit a nearby jewelry store for a precise measurement. This guide explains how weather and time of day can affect your finger size and helps you convert your measurement into various international sizes.
Step 1: Get Your Ring Sizer
We recommend using a dedicated ring sizer tool for accuracy. If you don’t have one, visit your local jewelry store where professionals can help you measure your finger for free.
Step 2: Measure at the Right Time
Your finger size can vary:
- Daily Changes: Measure in the late afternoon or early evening when your fingers are typically at their largest.
- Weather Effects: In warm weather, fingers may swell; in cooler conditions, they may contract. Avoid extreme conditions for the most accurate reading.
Step 3: How to Measure
If using a ring sizer:
a. Slide the ring sizer onto your finger.
b. Adjust until the fit is snug yet comfortable.
c. Record the inner diameter measurement in millimeters (mm).
If your measurement falls between two sizes, choose the larger size.
