Each method in the above link is desinged to help you scale your pepakura armour with ease and great accuracy. It is much easier to make a bicep than it is a helmet. Also, print a Bicep with the scaling you have decided for yourself to make sure that it fits properly. After you print, double check that all flaps have numbers on them. This may help other areas as well, where it could come through a bit tight. So you may want to add two or three inches to your actual height before doing the math. You don't really want the top of your head to be touching the top of the inside of the helmet if you expect it to fit right. Note: Keep in mind: the size of the default scale that's in use before you edit is from the base of the ground to the top outside of MC's helmet. You can use this formula to determine how big you should make your armor: The Master Chief is 7'2" tall 86 inches. Most of the newer models are already scaled properly for someone about 6' tall. If scaling is off, your finished model could be to big or to small. The term Scaling is referring to how big Pepakura will make the finished model. To change the page configuration from A4 to letter.
