Square Footage Formula:
| From: | To: |
Square footage is a measurement of area expressed in square feet (ft²). 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 formula for calculating square footage is simple:
Where:
Explanation: For rectangular or square areas, simply multiply the length by the width to get the total square footage.
Details: Square footage calculations are essential for determining material quantities for flooring, painting, or tiling projects; calculating property values; planning space utilization; and complying with building codes and regulations.
Tips: Enter the length and width measurements in feet. The calculator will automatically compute the square footage. For irregularly shaped areas, divide them into rectangular sections and calculate each separately.
Q1: How do I calculate square footage for irregular shapes?
A: Divide the space into rectangular sections, calculate each section's square footage separately, then sum all the areas together.
Q2: How do I convert square feet to square meters?
A: Multiply the square footage by 0.0929 to get square meters (1 ft² = 0.0929 m²).
Q3: 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.
Q4: How accurate should my measurements be?
A: For most purposes, measurements to the nearest inch (or 0.1 foot) are sufficient. For precise material ordering, more exact measurements may be needed.
Q5: How do I calculate square footage for a triangle?
A: For a right triangle, multiply the two sides that form the right angle and divide by 2. For other triangles, use the formula: Area = ½ × base × height.
