How Tall Is a Light Switch Cover

The standard size single switch or outlet cover plate is nominally 2.75 inches wide by 4.5 inches tall.

Are all switch plates of standard size?

There are three common wall plate sizes: standard, midsize/midway and jumbo. When selecting a size, the plate should completely cover the electrical box opening. If the opening is oversized, you may need a jumbo plate to conceal it.

How high are light switches off the floor?

For a majority of rooms, builders tend to place the bottoms of light switches 48 inches above the floor. This is a comfortable height for most home dwellers when sitting or standing, plus it makes it easier to install switches during construction.
