Square Footage Formula:
| From: | To: |
Square footage is a measurement of area expressed in square feet. It represents the total area of a two-dimensional space and is commonly used in real estate, construction, and interior design to quantify the size of rooms, buildings, and properties.
The calculator uses the square footage formula:
Where:
Explanation: The formula calculates the area of a rectangular or square space by multiplying the length by the width. For irregular shapes, the area can be calculated by dividing the space into regular shapes and summing their areas.
Details: Accurate square footage calculation is essential for determining property values, planning construction projects, calculating material requirements, and complying with building codes and regulations.
Tips: Enter both length and width measurements in feet. Ensure measurements are accurate and taken at the longest points for irregular shapes. All values must be positive numbers.
Q1: How do I measure irregularly shaped rooms?
A: Divide the space into regular rectangles or squares, calculate each area separately, then sum all areas together.
Q2: Does square footage include wall thickness?
A: Typically, interior measurements exclude wall thickness, while exterior measurements include it. Always clarify which standard is being used.
Q3: How do I convert square feet to other units?
A: 1 square foot = 144 square inches, 1 square foot ≈ 0.0929 square meters, 1 square foot ≈ 0.00002296 acres.
Q4: Should I measure in feet or convert from inches?
A: You can measure in feet directly or convert inches to feet (divide by 12) for more precise calculations.
Q5: How accurate should my measurements be?
A: For most purposes, measurements to the nearest 1/4 foot (3 inches) are sufficient. For precise work, measure to the nearest inch or centimeter.
