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.
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.
Details: Accurate square footage calculation is essential for determining material quantities for flooring, painting, or tiling; estimating construction costs; evaluating property values; and planning space utilization in residential and commercial settings.
Tips: Enter both length and width measurements in feet. Ensure measurements are accurate and in the same unit (feet). For irregularly shaped areas, divide them into rectangular sections and calculate each separately.
Q1: Can I use this calculator for non-rectangular areas?
A: This calculator is designed for rectangular areas. For irregular shapes, break them down into rectangular sections, calculate each separately, then sum the results.
Q2: How do I convert square feet to other area measurements?
A: 1 square foot equals 144 square inches, 0.0929 square meters, or approximately 0.00002296 acres.
Q3: Does square footage include wall thickness?
A: Typically, interior square footage measurements exclude wall thickness and measure only the usable living space.
Q4: How accurate should my measurements be?
A: For most purposes, measurements to the nearest inch (or 0.1 foot) provide sufficient accuracy. For precise calculations, measure to the nearest 1/4 inch.
Q5: Can I calculate square footage from measurements in different units?
A: First convert all measurements to the same unit (feet) before calculating. For example, convert inches to feet by dividing by 12.
