` = "Areas of a Room"`

Enter a value for all fields

The **Area of a Room** calculator computes the surface area of the ceiling, walls and floor of a room based on its height, length and width.

**INSTRUCTIONS:** Choose units and enter the following:

**(L)**Length of Room**(W)**Width of Room**(H)**Height of Room

**Room Areas (A): ** The calculator returns the surface areas in square feet. However, these can be automatically converted into compatible units via the pull-down menu.

The formula for the surface are of the floor and ceiling is:

A = L * W

where:

- A = surface area of ceiling or floor
- L = length of room
- W = width of room

The formula for the surface area of the walls is:

A = 2 * L * H + 2 * W * H

where:

- A = surface area of walls
- L = length of room
- W = width of room
- H = height of 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 square feet (area) of the ceiling, walls and floor of a room based on its height, length and width.**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.
