HOW TO MEASURE A WINDSOCK
Windsock sizes are based on the diameter of the large opening (throat) and the overall length of the windsock.
Measuring the length is easy, just measure from one end to the other (throat to apex).
When measuring the throat diameter, if you have windsock hardware already, simply measure the diameter of the ring.
However, measuring the diameter of the windsock can be tricky if all you have is the windsock and no windsock hardware holding it open. In this case, follow our easy instructions below to calculate the diameter accurately.
