Weather and temperature affect our mood and our fingers size, too: measure your fingers at different times of the day, better in the evening, when fingers can swell. When measuring the size, always remember that knuckles are usually wider, beware that thicker rings feel tighter than thinner ones.
We guarantee to send the size ordered, but we cannot be responsible for conversions or fittings if you order the wrong size.
A proper ring sizer or a jeweler help is always the best option, but in the meantime here you have a cheat sheet that can help you.
