Standard Sizes of Baseboard Registers

Baseboard Register Materials

• Many baseboard registers come in metal or plastic in neutral colors that are meant to be unobtrusive. Homeowners can paint the register to match the wall to make it seem to disappear in the area if they prefer. Baseboard registers are also available in brass, wood, cast iron and other decorative materials that match the decorating style in the room.

Standard Sizes

• Generally, baseboard registers are available in 15- and 18-inch widths with face plates that fit over any size height opening. Homeowners that cannot use the standard sizes may custom order baseboard registers that fit their needs. If the opening is wider than 15 or 18 inches, you can use two or more baseboard registers end to end to fit the space.

Measuring Baseboard Registers

• Remove the existing register with a screwdriver if an old one is already in the baseboard. Measure the width of the baseboard opening to determine the size of the register. The height measurement is not necessary for baseboard registers unless the space is obstructed or in a corner. If there is an obstruction, take the measurements of the overall space with you to purchase the register. This prevents the sides or top of the register from jutting out into a corner space or over a decorative feature where the available space is limited. Generally, the bottom edge of the baseboard register rests on the floor, but the top and sides may extend beyond the opening if the register is decorative. Keep this in mind when purchasing this type of register.

Cleaning Baseboard Registers

• Vacuuming the baseboard register with a crevice tool or brush attachment weekly keeps it free of dust. Another option is to use a feather duster or soft cleaning cloth to remove the debris. If the register is stained or heavily soiled, wipe it off with an all-purpose cleaner and a damp cleaning cloth. Use the cleaning solution recommended by the manufacturer if the register is made of brass, wood, cast iron or other special materials.
