How to Measure Your Ring Size at Home?

Before you start, remember that your ring size can change throughout the day, depending on temperature and activity. The best time to measure is in the evening when your fingers are slightly larger.

Things to Keep in Mind

Time & Temperature: Measure at the end of the day for best accuracy.
Ring Width: Wider bands fit more snugly. Choose half a size larger for widths over 4 mm.
Comfort Fit: Your ring should slide over the knuckle with light resistance but feel secure.
Finger Shape: If you have prominent knuckles, size up slightly to ensure comfort without looseness at the base.
