Do You Need a Backing Plate for a Wood Switch Plate? How to Check Before You Order

My wood switch plates are completely flat, about 1/8″ thick. That means if your switch or outlet sits out from the wall a little, the plate can end up sitting slightly off the wall instead of flush against it. Some folks actually like that floating look. If you don't, a backing plate closes the gap. This short video covers how to tell which camp you're in before you order.

Why a Flat Plate Can Sit Off the Wall

A flat plate rests on whatever is closest to it. When the device face sits flush with the wall, the plate sits flush too. When the switch or outlet sits out from the wall, the plate rests on the device and you see a small gap around the edges. Whether that gap bothers you is a matter of taste.

Check Before You Order

The easiest way to know for sure is to test it with cardboard first. I put together free true-size test templates you can print at home:

If you're not sure which template matches your device, my posts on what a gang is and toggle, Decora and duplex devices will help you pick the right one.

How Backing Plates Are Sized

Backing plates are sized by gang, from 1 to 6, just like the front plates. A duplex outlet takes a single. You've got a few options for getting one:

If you go the do-it-yourself route, there's a short video on attaching a backing plate, and another on removing one if you change your mind. You can find backing plates in 1 to 6 gang here, and the full lineup of VARØ Industries wood switch plates on the site. For sizing, wood types and fit details, see switchplates.info.

Safety first: I'm not a licensed electrician; I just make switch plates. Any work on electrical system components is done at your own risk and/or should be done by a licensed professional. Always turn off power at the breaker and verify it's off before working near wiring.
