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, or land parcels.
The calculator uses the simple area formula:
Where:
Explanation: This 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 valid positive numbers.
Q1: How do I measure irregularly shaped rooms?
A: Divide the space into rectangular sections, calculate each area separately, then sum all areas for the total square footage.
Q2: Does square footage include wall thickness?
A: Typically, interior measurements are taken from inside wall to inside wall, excluding wall thickness. Exterior measurements include walls.
Q3: How accurate should my measurements be?
A: For most purposes, measurements to the nearest inch or half-foot are sufficient. Professional applications may require more precise measurements.
Q4: Can I use this calculator for metric measurements?
A: This calculator is designed for feet. For metric measurements, convert to feet first or use a square meter calculator.
Q5: How is square footage used in real estate?
A: Square footage is a key factor in property valuation, price per square foot calculations, and comparing similar properties in the market.
