One of the most important things to consider when buying a ring is to determine your ring size.
Measure your finger and find the size, step by step.
Cut a piece of paper (at least 1 cm and at least 3 long) and make sure it is long enough to wrap around your finger. You can also use a string if it is easier for you. Do not have a string or paper? Try dental floss.
Allow enough space for your finger to move, giving your hand mobility. - If the ring you have in mind is wider in width, give your finger extra space to move. Keep body weight and weather fluctuations in mind. This helps prevent the finger from swelling and the string or paper (which later becomes the ring) from becoming too tight. Sometimes the best time to measure your finger is in the evening. In the colder seasons, your fingers may be smaller than in the hot summer months.
Wrap the string or paper around your finger.
Mark the ends of the paper or string where they meet with a ballpoint pen or similar.
Measure the selected area.
If you have measured the circumference of your finger to 4.5cm (equivalent to 45mm) then you must use size 45.
