Every size that a human mind can imagine. I probably got carried away there a bit, but shower heads can be as small as 3 inches.Moen’s six-function handheld showerhead is a good example of that. It’s only 3.5 inch.

However, The size of the shower head depends on the type of shower head installed.

There are mainly three types of mounts for shower heads – ceiling, bar, and wall mount.Depending on the chosen mount, the shower head can range anywhere from 5 inches to 60 inches in diameter.

I would feel happy to share an industry-standard model with you, but it’s more complicated than that. Depending on the types, features, and mounts, the shower head size needs to be different.

However, in the USA, a 5-inches (five-inch) shower head is considered standard. The fixed shower head, which is the most popular type, has a standard size. Given the wall-mount design, the fixed shower head may often reach heights of 8 inches, but they are uncommon.

• Regular Shower Head Size

The regular shower head is the standard fixed shower head. The size ranges from 3 inches to 6 inches in diameter. But 4 inches is the most widely used variant.

A shower head with a larger diameter lets more water flow at one time, which may be desirable for people who have trouble getting the water to spray evenly.

• Rain Shower Head Size – Round and Square

There is a lot of confusion regarding the rain shower head size. The size of rain shower heads typically varies from 6 to about 17 inches, though the vast majority of brands carry products from 8 to 12 inches.

However, In an average bathroom, we usually prefer 12-inch rain shower heads.

• Handheld Shower Head

The handheld shower heads come in several configurations depending on the size of their different components. The actual shower head size ranges from 3.5 inches to 6 inches. The handle size can go up to 8.5 inches.

Most brands I looked at had an average of 5.5 inches. This is because it is convenient for most people and allows easier access.

The shower head holder has generally placed anywhere between 60 inches to 80 inches, depending on shower area dimensions.

• RV Shower Head

Almost every shower head in the USA comes in a single size. This is done to bring universal fit and minimize replacement costs. Though there might be exceptions, you need to understand NPT and BSP.

NPT means National Pipe Thread Tapered, while BSP stands for British Standard Pipe. Across the USA, the NPT size is most widely used, whereas the BSP is used outside of the USA in most of Europe, Africa, and Asia.

Since there is only a single connection size for all types of shower heads, chances are it might be a thread taping issue if the shower head doesn’t fit.

If it’s a DIY project, make sure you have the right type of thread tape and the right amount of spins to get the optimum fit. Under-taping or over-taping a connector will cause a mismatched fit.

The standard thread size of a shower head in the USA is ½ inch NPT. This is the standard for any modern shower head connection. Shower pipes will easily fit any thread of this size unless there are special installation mechanisms required, like the rain shower heads.

For the rest of the world, the ½-inch BSP is considered the standard with very few special exceptions.
