The height of my head from the chin to the top is around 31 cm. I go to scale factor and type 320mm to the height. Then i measure the height of the helmet and it shows the helmet is only 134mm high. I feel really confusing because this is the first time i used pepakura. So can somebody help me to scale it? Thanks alot.
