**First, find a piece of string. Now, wrap the string around the pipe and mark the point where the string crosses. The length between the marks gives you the pipe size.**

## How to Measure Irrigation Pipe Size?

Measuring irrigation pipe size is essential for any irrigation project, as it helps to ensure the proper flow of water through the system. Knowing the size of an irrigation pipe can also help determine the amount of water needed for a particular application. As such, it is important to take the time to measure irrigation pipe size properly in order to ensure the best results.

The first step to measuring irrigation pipe size is to determine the inner diameter of the pipe. This measurement is taken by inserting a ruler or measuring tape into the pipe and measuring the inside diameter. The most common inner diameter measurements for irrigation pipes are ½ inch, ¾ inch, 1 inch, 1 ½ inches, and 2 inches. Once the inner diameter is known, the outer diameter can be calculated by adding the wall thickness of the pipe to the inner diameter.

The next step to measure irrigation pipe size is to calculate the flow rate. This is done by multiplying the inner diameter of the pipe by the length of the pipe, and then dividing the result by the number of gallons per minute (GPM) that the pipe is capable of delivering. This calculation is important as it will help determine the pressure needed to push water through the system.
