    How to Calculate Wall Size Based on OD and ID | Hunker

    The outside of a pipe is always larger than the inside. The difference between the inside diameter, or ID, and the outside diameter, or OD, is caused by the thickness of the walls. By calculating the difference between the inside diameter and the outside diameter it is possible to determine the size, or thickness, of the pipe walls. The process uses basic math and requires no previous plumbing ...
