Measure the length and width of the room. Calculate the square footage of your room by multiplying the length of the room times the width of the room.
Measure the length and width for each piece of furniture in feet. Find the square footage for each by multiplying the length and the width.
Calculate the square footage, or area, for round items, such as tables, by using the formula for the area of a circle. Measure the distance around the circular object in feet to find the circumference.
Calculate the radius: circumference / 6.28.
Then calculate the area: 3.14 x radius squared.
Designate a square footage for each square on your grid. The most common measurement is 1 square foot, meaning one grid square equals 1 square foot. Draw a box inside the grid that represents the entire area of the room. The sides of the box represent the room's length, while the top and bottom represent the width.
Use the measurements you found in Steps 2 and 3 to arrange your furniture on the grid. For example, if the width of your couch is 2 feet and the length is 4 feet, it will take up eight squares on the grid, with two down and four across. If the area of your round table is 9 square feet, it will take up a total of nine spaces on the grid, with three across and three down.
Things You Will Need
- Grid paper
- Measuring tape
- For odd shaped furniture, such as an L or U shaped desk, break the item into imaginary pieces that are easier to work with. Then, calculate the square footage for each separate piece.
