A diameter tape measure can save you a lot of time and frustration when you want to find the OD (outside diameter) of a pipe, post, or tree. This special tape has the inch scale (or metric scale) stretched out by a factor of pi (3.14159). So, if you wrap it around the pipeline, you will not see the “circumference”. You will see its diameter. You don’t need to divide your answer by 3.14159.

Here’s the Secret About a Pipe Measuring Tape

If you have to find the length of a pipe, that’s easy. But what about the outside diameter of a pipe?  What if you can’t just measure the diameter at the end? What if the pipe doesn’t have its ends exposed. It is part of a piping system, or a pipeline. How can you fine the OD, or outside diameter?

The secret is finding the right pipe measuring tape. What is it called?

  • Diameter Tape
  • Pipe Tape
  • Pipe Diameter Tape
  • Pi Tape
  • OD Tape
  • Outside Diameter Tape
  • Circumference Tape (a misnomer, but they are sometimes called this)

To use one, all you do is wrap it around the pipe, and read off the diameter. You don’t need to divide by pi (3.14159).
