To measure window area, you calculate the square footage. This is achieved by multiplying the length and width of the window, and then making necessary conversions to feet.
Calculating Window Area in Square Feet
Here’s a step-by-step process to accurately determine the square footage of a window:
-
Measure the Length and Width: Measure the length and width of your window using a measuring tape.
- Record these measurements in inches. Since windows often have irregular sizes, inches provide more precise measurements.
-
Multiply Length by Width: Once you have both measurements in inches, multiply them together:
Length (inches) x Width (inches) = Area in Square Inches
-
Convert Square Inches to Square Feet: To obtain the area in square feet, divide the area calculated in square inches by 144 because there are 144 square inches in one square foot:
-
(Area in Square Inches) / 144 = Area in Square Feet -
Formula:
(Length in inches * Width in inches) / 144 = Area in square feet
-
Example Calculation
Let's say you have a window that measures 36 inches in width and 60 inches in length:
- Step 1: Length = 60 inches, Width = 36 inches.
- Step 2: Area in square inches = 60 inches * 36 inches = 2160 square inches
- Step 3: Area in square feet = 2160 square inches / 144 = 15 square feet
Therefore, the window area is 15 square feet.
Practical Tips
- Multiple Windows: For calculating total window area in a room, repeat the above steps for every window, then add up the individual square footage calculations.
- Accuracy: To ensure accuracy, always measure twice.
- Odd Shapes: If you have windows that are not rectangular, it may be necessary to break the window into smaller rectangles, measure each part, add them up to get total area.
By using these instructions, you can effectively measure window area accurately, converting from inches to square feet.
