Method 2: Wrap a paper strip or string around your finger, mark and measure it, then refer to our size chart.
Tips for Accurate Ring Measurement:
- Measure your finger in the evening when it's slightly larger.
- Ensure your hands are warm, as cold temperatures can shrink your fingers.
- Avoid measuring after consuming alcohol or salty foods, as they can cause swelling.
- If your knuckle is larger than the base of your finger, measure both and choose a size that slides on comfortably.
