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 land parcels.
The calculator uses the square footage formula:
Where:
Explanation: The formula calculates the area of a rectangular space by multiplying its length by its width. For irregular shapes, the area can be calculated by dividing the space into smaller rectangles.
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 taken at the longest points for accuracy. All values must be positive numbers.
Q1: Can this calculator be used for non-rectangular spaces?
A: This calculator is designed for rectangular areas. For irregular shapes, divide the space into rectangular sections, calculate each separately, then sum the results.
Q2: How do I convert square feet to other units?
A: To convert to square meters: multiply by 0.0929. To convert to square yards: multiply by 0.1111. To convert to acres: divide by 43,560.
Q3: Why is square footage important in real estate?
A: Square footage directly affects property valuation, pricing, and comparability with similar properties. It's a key factor in determining market value.
Q4: How accurate should my measurements be?
A: For most purposes, measurements to the nearest inch or centimeter are sufficient. For precise calculations (like construction), measure to the nearest 1/8 inch or millimeter.
Q5: Does square footage include wall thickness?
A: Typically, interior measurements exclude wall thickness (measuring from inside surfaces), while exterior measurements include walls. Always clarify which standard is being used.
