When you’re installing drywall or paneling, small mistakes can leave big gaps around electrical boxes. Luckily, there’s a product made just for this situation. “Oversize” cover plates ($1) for
switches and outlets are available in standard colors at home centers and hardware stores. They’re 1/2 in. to 3/4 in. longer and wider than standard plates, so they can be a bit conspicuous. Electrical codes don’t allow gaps wider than 1/8 in. around boxes, so fill gaps with joint compound or caulk before you screw on the cover plate.
