Square Feet Formula:
| From: | To: |
Square feet calculation is a fundamental measurement used to determine the area of a two-dimensional space. It's commonly used in construction, real estate, interior design, and landscaping to measure floor space, wall areas, and property sizes.
The calculator uses the simple area formula:
Where:
Explanation: To find the area in square feet, simply multiply the length measurement by the width measurement. Both measurements must be in the same unit (feet).
Details: Accurate area calculation is essential for determining material quantities, estimating costs, planning space utilization, and complying with building regulations. It's used in flooring installation, painting, landscaping, and property valuation.
Tips: Enter both length and width measurements in feet. Ensure measurements are accurate and taken at the longest/widest points for irregular shapes. For non-rectangular areas, break them down into rectangular sections and calculate each separately.
Q1: How do I convert inches to feet for calculation?
A: Divide inches by 12 to convert to feet. For example, 18 inches = 18/12 = 1.5 feet.
Q2: Can I use this for non-rectangular areas?
A: This calculator is designed for rectangular areas. For irregular shapes, divide them into rectangular sections, calculate each separately, then sum the results.
Q3: How accurate should my measurements be?
A: For most purposes, measuring to the nearest 1/4 foot (3 inches) is sufficient. For precise work like tile installation, measure to the nearest 1/12 foot (1 inch).
Q4: What's the difference between square feet and linear feet?
A: Square feet measure area (length × width), while linear feet measure length only. Linear feet are used for materials sold by length, like molding or fencing.
Q5: How do I calculate square feet for a room with multiple sections?
A: Measure each rectangular section separately, calculate the area for each, then add all the areas together for the total square footage.
