Measure your ring size at the right time: Finger size can change throughout the day due to temperature and physical activity. For the most accurate results, measuring your intended finger in the afternoon or evening when your fingers are typically warmer is best. Avoid measuring your finger in the morning or when it is cold or damp, as fingers tend to shrink in colder conditions. Also, since engagement rings and wedding bands are commonly worn on the left ring finger, measure the exact finger where you intend to wear the ring. Measure ring size a few times: To obtain the most accurate ring size, measure your finger at least 3-4 times. Use a non-stretchable material: When measuring ring sizes using a string or piece of fabric, ensure you use a non-stretchable material to avoid obtaining the wrong ring size. Consider the ring width: Wider bands and rings generally have a snugger fit compared to thinner ones. When measuring your ring size or your partner's ring size, ensure you measure a ring with a similar width to the one you plan on purchasing. Additionally, you may need a half-size or full-size higher for a comfortable fit if you opt for a wider band. Consider your knuckle size: The ring typically sits on your knuckle, so if your knuckle is larger than the base of your finger, measure both your knuckle and your finger. Then, choose the average of both measurements as your ring size.
