There was a lot of questions about grip size and how to choose the right one. The answers were mainly like "choose the one which is comfortable for you" or "not too small and not too big". This is very confusing for beginners when they want to buy their first racquet. If somebody know my threads he knows that I like researches (maybe because I'm a scientist ), so let's make a research about correlation between your grip size and the size of your hand! From tennis I know, there is a simple way to measure the hand size. It is presented in the picture below: (from http://www.tennis-warehouse.com/LC/Gripsize/Gripsize.html) "With your hand open and fingers extended close together, align the ruler with the bottom lateral crease of your palm and measure to the tip of your ring finger." If you express this measurement in inches you get the ideal grip size of tennis racquet. Now I call you to tell your hand size and the circumference (in cm or inch) of your badminton grip (in the middle) for which you feel is the best for you. My hand (from bottom lateral crease to the tip ring finger) = 113 mm = 4.45 inch Grip size (circumference) = 95 mm = 3.74 inch.
