The Area of the Walls in a Room calculator computes the surface area of the interior walls in a rectangular room based on the length, width and height of the room.
INSTRUCTIONS: Choose units and enter the following:
- (L) Length of Room
- (W) Width of Room
- (H) Height of Room
Total Area (A): The calculator computes the area in square feet. However, this can be automatically converted into other area units via the pull-down menu. Note, this does not include the ceiling or floor.
The Math / Science
The formula to compute the surface area of walls in a room is:
`A = (2*L*H + 2*W*H)`
where:
- A = interior surface area of a room (excluding the floor and ceiling)
- L = length of the room
- W = width of the room
- H = height of the room
- Volume of a Room: Computes the cubic feet (volume) of a room based on its height, length and width.
- Areas of a Room: Computes the total square feet (area) of a room based on its height, length and width. This includes the total area of the ceiling and walls for things like paint. It also individually includes the area of the ceiling, walls and floor of a room.
- Room Paint Cost: Estimates the gallons of paint needed and associated cost to paint a room based on the room dimensions, number of coats and the unit cost of paint per gallon.
- Wallpaper for a Room: Computes the number of rolls of wallpaper needed to cover the walls of a room based on the dimensions of the room and the rolls of wallpaper.
- BTUs per Hour to Heat a Room: Computes the energy (heat) required to heat a space of a certain volume by a specified temperature variance.
- Insulation Rolls for Walls of a Room: Computes the number of rolls or batts of insulation needed for the WALLS of a room based on the length and height of the four walls. The calculator assumes standard 16" spacing on the studs.
- Drywall Materials for a Room: Computes the number of drywall boards (4x8 or 4x12), number of drywall nails or screws and gallons of joint compound need for a room based on the room's dimensions.
- Ceiling Tiles for a Room: Computes the number of ceiling tiles needed to cover the ceiling of a room based on the dimensions of the room and the tiles.
- Cost of Flooring a Room: Computes the square feet of a room and then applies the price per square feet of different flooring products (e.g., hardwood, carpeting, tile)
- Room Framing Cost: Computes the number of studs and plate boards for a room and estimates the cost of framing based on the unit price of the lumber.
- Outlets and Wiring for Room: Computes the number of outlets (boxes) and length of wire to connect them in a room based on the room dimensions and the outlet spacing.
