Place your right hand on a piece of paper and draw a vertical line between your thumb and index finger, and then draw another line vertically from the bottom of your little finger (see the example on the diagram below. Not 1:1 scale so don't use the screen to measure your hand). Then measure the horizontal distance between the two lines and double it, this is your approx. palm circumference. Use the size chart below to find your hand size and the glove size for you.
