To calculate the correct flat width of poly tubing needed to cover your product, there are two easy ways to determine the right answer. Poly tubing is sold by lay flat width x length in feet. It is important to remember this is the "lay flat" measurement and not the “diameter” of the tubing when opened fully. View a Printable Version of this InfoGraphic
Diameter Based Measurement
Width of the widest distance from one side to the other:
Multiply the diameter of your product (in inches) times 3.14, divide the result by 2, then add half an inch or more, to the width of the poly tubing, so that your tubing can be pulled around your product.
Diameter Based on Product Circumferance
Total Distance all the way around the object:
With this measurement, you can simply divide the circumference by two, then add a half inch or more to allow the tubing to be pulled around your product.
C=Circumferance: ( C÷2 ) + 1/2" = Tubing Width
For tighter fit, add only a 1/2 inch. For loose fit, ad up to 4 inches.

Please be aware of industry standard variances in manufacturing, regarding width tolerances of poly tubing.
