Getting an address plaque that’s just the right size is extremely important. There are a few things you may consider when figuring out the perfect plaque size for your situation. Small address plaques measuring under 4”x12” or 6”x12” may work fine for smaller places that often do not have driveways, such as apartments, rowhouses, etc. Standard address plaques may be a good option for houses smaller than 3,000 sq ft or ones that are less than 50 ft away from the curb. For bigger properties, you may need more than one standard plaque or get an estate-size option.
