Follow these Tips to measure accurate ring size
- Measure a few times: Measure your finger a few times to be sure. Try it on different days and at different times.
- Room temperature matters: Measure your finger when it’s not too hot or too cold for the most accurate size.
- Wider fingers, wider band: If your fingers are wider, use a wider band for a comfy fit.
- Think about the ring style: Different rings fit differently. Wide bands might need a slightly larger size than delicate ones.
- Check for bumps: If you have bumps or knuckles, measure at the widest part for a smooth fit.
