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: This 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. All values must be positive numbers.
Q1: Can I use different units of measurement?
A: This calculator uses feet as the standard unit. If you have measurements in other units, convert them to feet first (1 foot = 12 inches, 1 meter ≈ 3.28084 feet).
Q2: How do I calculate square footage for irregular shapes?
A: Divide the irregular shape into regular shapes (rectangles, triangles), calculate each area separately, then sum them together.
Q3: Does square footage include wall thickness?
A: Typically, interior square footage measurements are taken from the interior walls, while exterior measurements include wall thickness. Always clarify which standard is being used.
Q4: How accurate should my measurements be?
A: For most purposes, measurements to the nearest inch or centimeter are sufficient. For precise calculations, measure to the nearest 1/8 inch or millimeter.
Q5: Can this calculator be used for three-dimensional spaces?
A: This calculator is for two-dimensional area calculations. For volume calculations, you would need to multiply area by height.
