Which of the following is the standard diameter for a sprinkler head?

Explanation:
Sprinkler heads are designed to thread into piping with a standard connection size, which is 1/2 inch NPT. This size has become the norm because it provides a reliable balance between flow and compatibility with the typical piping and sprinkler bodies used in most residential and light commercial systems. While larger connections exist for specialized, high-flow applications, they are not the standard for most installations. So the standard diameter for a sprinkler head is 1/2 inch.
