How to choose the size

• You open the end of the heat shrink to go over the object. This means that the circumference of the heat shrink you need should be larger than the object you want to fit over. The measurements you are choosing above are the flat widths of the heat shrink. Since you open the heat shrink then the circumference of the heat shrink is twice the flat width. So if your object is 200mm circumference you need a flat width of 120mm approximately (more than half).
• If you want to convert flat width to round width, multiply flat width by 2/pi.
• You can use much larger heat shrink because of the large shrinkage ratio of PVC heat shrink. Slowly apply heat due to the low melting temperature of PVC. Even a hair dryer of reasonable quality is hot enough. If using a flame then keep the flame at a large distance away.
