Take measurements at different times of day and average the results for the most accurate size.
Fingers are typically smaller in the morning and can swell in heat or after exercise. Measure at different times.
Each finger can be a different size, even on the same hand. Measure the exact finger you'll wear the ring on.
Wider bands (6mm+) typically require going up half a size for comfort.
Your ring should slide over your knuckle with slight resistance but feel comfortable once on.
It's easier to size a ring down than up.
