Rings
To find your ideal ring size, measure at the end of the day when your fingers are at their largest. Consider the width of the band—thicker bands tend to feel tighter, so you may want to choose a size up. Your ring sizer should fit comfortably: snug enough to stay on securely, but loose enough to slide over your knuckle with ease.
