what size is a garden hose fitting

The size of a garden hose fitting depends on the thread size of the hose. The most common thread size for garden hoses in the United States is 3/4 inch with 11.5 threads per inch, known as the NH or National Hose designation. This thread size is designed to fit a standard garden spigot, nozzle, or sprinkler system. Other common thread sizes include 1/2 inch and 5/8 inch. It is important to note that the thread size of the hose does not refer to the internal or external diameter of the hose, but rather the diameter of the threaded fitting inside the hose.
