How to Measure Pool Hose Diameter – A complete Guide

To measure the diameter of a pool hose, you will need a measuring tape. Start by placing one end of the measuring tape at the center point of the circumference. Then, pull it around so that it is taut and measures half way around the circumference.

The distance between these two points should be equal to half of the total circumference, which can then be multiplied by 2 to calculate its full diameter. Alternatively, if you have access to calipers or dividers, you can use those as well for more accurate measurements. After obtaining your measurement in inches or centimeters, divide this number by pi (3.14).

This final figure will give you an exact representation of your pool hose‘s diameter in either inches or centimeters depending on what unit was used initially when taking measurements with your chosen tool(s).

  • Gather the necessary tools – You will need a ruler or tape measure and some type of marker, such as a pencil
  • Place the end of the ruler against one end of the hose – Make sure that you place it firmly so that there is no slipping when you start measuring
  • Mark where the other end of the hose meets with your marker – This will indicate where to stop measuring from in order to get an accurate measurement
  • Measure between these two points with your ruler or tape measure – The distance between these two points is your pool hose diameter measurement (in inches)
