What if the ring turns out to be too small to fit her little finger or too large to be held in the finger?

To avoid such occurrence of any disasters in that magical moment of love, due to misfit of engagement ring or wedding ring, an international chart depicting the standard ring sizes in different countries has been included.

Just follow the simple steps and discover the correct size for her ring, no need to make a guess. Get the excellently crafted ring in perfect size for a perfect celebration of love and relationship.
Step 1: As for first step, take one her old rings that she wears on left ring finger or you can take a thin strip of paper and encircle the long paper strip snugly around the base of her ring finger and mark the meeting junction or you can tear off the extra length of the strip.
Step 2: Take a scale that has inches or millimeters (mm) marked on one side at least to measure the standard ring size of your lady. If you are measuring the size via old ring, then you have to refer to the inner diameter chart and in case of paper strip, refer to the inner circumference chart. If the scale has markings in centimeters, then you can convert it to inches by multiplying the attained value with .3937 or millimeters by multiplying the attained value by .1.
Step 3: In case of measurement via ring, place the zero mark of the scale at an inner arc of the ring in such a way that it passes through the center and reaches the opposite inner arc of the ring. Thus you will get the value of exact diameter of the ring and then you can refer the chart to obtain the size of the ring according to the deduced diameter. Ring sizes given in the chart vary according to the standards prevalent in that country, so follow the size according to your place. Refer step 4 if you have used paper strip to measure size.
Step 4: In case of paper strip, hold both the ends of the strip firmly or clip the ends on a board and then use a scale to measure upto the marked length. Thus, the inner circumference of the ring is detected, so refer the ring size that matches the circumference that has been obtained.
