Square Footage Formula:
| From: | To: |
Square footage is a measurement of area expressed in square feet. It represents the total surface 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 simple area 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 taken at the longest points for accuracy. All values must be positive numbers.
Q1: How do I measure irregularly shaped rooms?
A: Divide the space into rectangular sections, calculate each section's square footage separately, then add them together for the total area.
Q2: Does square footage include wall thickness?
A: Typically, interior measurements are taken from wall to wall (excluding wall thickness). Exterior measurements include the entire structure.
Q3: How do I convert square feet to square meters?
A: Multiply square footage by 0.0929 to get square meters (1 sq ft = 0.0929 sq m).
Q4: Should I measure in inches and convert?
A: You can measure in inches and divide by 12 to get feet, or measure directly in feet for more accuracy.
Q5: How accurate should my measurements be?
A: For most purposes, measurements to the nearest 1/4 foot (3 inches) are sufficient. For precise calculations, measure to the nearest inch.
