How do I measure pipe diameter?

When ordering pipe beam swing hangers, it is very important to know with confidence what your pipe diameter for the top beam is. Unlike wood beam swing hangers that will fit a number of different beam widths, pipes are not as accommodating. The last thing you want is to end up with swing hangers that are too big or too small for your pipe beam, so we always encourage customers to measure twice, and order once!

Determining the pipe diameter is quite simple. Using a fabric tape*, first measure the circumference of the pipe. Once you have this measurement, get out your calculator and divide the circumference by Pi (3.142). This will give you the decimal amount for your pipe diameter.

The four pipe beam swing hanger sizes we carry and their measurements (± 1/8") are as follows:

Pipe Circumference Pipe Diameter
7-1/2" 2-3/8"
11" 3-1/2"
14-1/8" 4-1/2"
15-3/4" 5"

* If there is no fabric tape handy, you can also use a piece of string. Wrap the string around the pipe and mark where the ends meet. Then lay the string flat and use a tape measure to get the circumference amount.
