Electrical Faceplate Types and Dimensions

Electrical faceplates, also called wallplates or coverplates, come in an infinite array of combinations, sizes, and shapes. However, there are some standard sizes for basic faceplates. Dimensions for faceplates and other electrical devices are covered by ANSI/NEMA WD 6, Wiring Devices - Dimensional Specifications.

Electrical Faceplate Types

There is a wide array of devices that can be accommodated by an electrical faceplate including: receptacles, switches, motion sensors, telephone jacks, data jacks, dimmers, etc. Some of the more common faceplate configurations are shown below.

Gangs

Gangs refer to the number of vertical groups of openings that are accommodated. The devices can change between gangs. For instance, in a 4 gang electrical box, one could have any combination of devices (1 toggle switch and 3 duplex outlets; or 2 toggle switches and 2 duplex outlets; or 1 toggle switch, 2 duplex outlets, and 1 tele/data; etc).

Electrical faceplates come in 1-gang up to 10-gang. Shown below are 1-gang through 4-gang.

Standard Size Electrical Faceplates

All standard size faceplates are 4.490" in height. Widths are listed below. Please note that these sizes are standard; however, your faceplates may not match.

Oversized or Jumbo Faceplates

The NEMA standard does not recognize oversized or jumbo faceplates. However you may need to specify jumbo plates in renovation projects where the drywall or plaster hole is larger than a standard plate will cover. A Jumbo electrical faceplate is 5.50" tall. Widths are listed below, but we recommend checking with the manufacturer since sizes may vary.
