Is pipe size OD or ID?
For sizes larger than 12-inch, NPS corresponds to the actual outside diameter. For each nominal pipe size, the outside diameter (O.D.) remains relatively constant; the variations in wall thickness affect only the inside diameter (I.D.).
How do you measure the diameter of a steel pipe?
Here are a few ways to measure:
- Direct Diameter measurement is the easiest. Measure at the end of the pipe.
- Direct Diameter measurement with a caliper (useful if the end is not accessible) 1 1/2″ pipe.
- Measure circumference using a flexible tape and divide the outside circumference by 3.1415.

What is OD pipe size?
OD and Nominal Pipe Size Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS).
