                          RING SIZE

                           (Measuring your finger)
                           ITEMS YOU'LL NEED:
                          A marker
                          Cut an even strip of paper.
                          On the finger you wish to measure, wrap the slice of paper around the base of the finger, just below the knuckle. 
                          Ensure that the paper is wrapped tightly around your finger for a secure fit.
                          Mark the spot where it meets.
                          Measure the distance with a ruler (in mm); that’s your fingers circumference.


                          PRO TIPS FOR MEASURING:
                          Double check your knuckle measurement as some people need to size up to fit rings over knuckles.
                          Throughout the day, our fingers tend to swell. Your best bet is to measure your fingers at the end of the day for the most accurate fit.
                          Be sure that your hands aren’t too cold. When we’re cold, our fingers shrink in size. Measure when the temperature is just right. 

                          WRIST SIZE

                          To measure your wrist size, you can use a flexible measuring tape or a piece of string.
                          Tape measure
                          This is the most accurate method. With your palm facing up and fingers spread, place the end of the tape measure in the middle of your wrist and wrap it around snugly. Measure in inches or centimeters. For bracelets, you can add half an inch to your measurement to determine the right size.
                          String and ruler
                          Wrap a piece of string around your wrist where you'd normally wear a watch, not too tightly. Mark or hold the string where it meets the starting point, then lay it flat on a ruler and measure the length. You can also use other materials like yarn, dental floss, ribbon, or shoelace.
