Square Feet Formula:
| From: | To: |
Square feet is a measurement of area calculated by multiplying length by width. It's commonly used in real estate, construction, and interior design to measure the size of spaces, rooms, and properties.
The calculator uses the simple area formula:
Where:
Explanation: This formula calculates the area of a rectangular or square space by multiplying the two perpendicular measurements.
Details: Accurate area calculation is essential for determining material requirements, space planning, property valuation, and compliance with building regulations.
Tips: Enter both length and width measurements in feet. Ensure measurements are accurate and in the same unit (feet). The calculator will automatically compute the area in square feet.
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.
Q2: How do I measure irregularly shaped areas?
A: For irregular shapes, divide the area into rectangular sections, calculate each separately, then sum the results.
Q3: What's the difference between linear feet and square feet?
A: Linear feet measure length in one dimension, while square feet measure area in two dimensions (length × width).
Q4: How accurate should my measurements be?
A: For most applications, measurements to the nearest 1/4 foot (3 inches) are sufficient, but precision requirements may vary by application.
Q5: Can this calculator be used for circular areas?
A: No, this calculator is designed for rectangular areas. Circular areas require the formula: π × radius² (then convert to square feet).
