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 space by multiplying the length by the width. For irregular shapes, the area can be calculated by dividing into smaller rectangles.
Details: Accurate square footage calculation is essential for determining property values, planning construction projects, calculating material requirements, and ensuring proper space planning and utilization.
Tips: Enter both length and width measurements in feet. Ensure measurements are accurate and in the same unit (feet). All values must be positive numbers greater than zero.
Q1: Can I use different units for length and width?
A: No, both measurements must be in the same unit (feet) for accurate square footage calculation. Convert other units to feet first.
Q2: How do I calculate square footage for irregular shapes?
A: Divide the irregular shape into smaller rectangles, calculate each area separately, then sum all the areas together.
Q3: What's the difference between square feet and square meters?
A: Square feet is the imperial unit of area, while square meters is the metric unit. 1 square meter equals approximately 10.764 square feet.
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 closest fraction of an inch.
Q5: Can this calculator be used for three-dimensional spaces?
A: No, this calculator is for two-dimensional area calculation. For volume calculations, you would need to include height measurements as well.
