Step 1: Prepare Your Tools

• You will need a ruler that shows millimeters (mm) for accuracy.
• Optional: A thin strip of paper or string if you do not have a flexible measuring tape.

Step 2: Measure Your Finger

• Select the finger on which you will wear the ring.
• Use the ruler to measure the width of your finger at its thickest part (usually the base of the finger or the knuckle if it’s notably larger).
• If using paper or string, wrap it around the widest part of your finger. Mark where the end meets and measure the length against a ruler.

Step 3: Record the Measurement

• Note down the measurement in millimeters. This is the diameter of your finger.

Step 4: Find Your Ring Size

• Use the measurement to find your size on the provided ring size chart. The chart should list diameters in millimeters alongside the corresponding ring sizes.

Step 5: Account for Finger Width

• If your finger has a broader knuckle, measure both the base of your finger and your knuckle, and select a size that accommodates both measurements, ensuring the ring will slide over the knuckle comfortably.

Why Choose the Larger Size When Between Sizes?

• Comfort: A slightly looser ring is generally more comfortable, especially if your fingers tend to swell during the day or in warm weather.
• Ease of Removal: Rings that are a bit larger are easier to remove without struggling, which is particularly important for daily wear items.
• Accommodating Changes: Your finger size can slightly change throughout the day and with varying temperatures. A larger size can accommodate these fluctuations better, preventing the ring from becoming too tight.

Additional Tips:

• Measure at the End of the Day: Your fingers are at their largest at the end of the day due to blood circulation and activity.
• Don’t Measure Cold Fingers: Fingers can be smaller than usual in cold temperatures, which might result in choosing a ring size that’s too tight.
• Consider the Band Width: Wider bands often require a larger size. If your chosen ring has a wide band, consider going one size up from what your measurement indicates.
