Square Footage Formula:
| From: | To: |
Square footage is a measurement of area expressed in square feet. It represents the total surface area of a space and is commonly used in construction, real estate, and interior design to quantify the size of rooms, buildings, and properties.
The calculator uses the square footage formula:
Where:
Explanation: This formula calculates the area of a rectangular space by multiplying its length by its width.
Details: Accurate square footage calculation is essential for determining material quantities for flooring projects, estimating costs, planning layouts, and ensuring proper coverage without excess waste or shortage.
Tips: Measure the length and width of your space in feet, enter both values, and click calculate. For irregularly shaped rooms, divide into rectangular sections and calculate each separately.
Q1: How do I measure irregularly shaped rooms?
A: Divide the space into rectangular sections, calculate each area separately, then add them together for the total square footage.
Q2: Should I add extra for waste?
A: Yes, it's recommended to add 5-10% extra to account for cutting waste, pattern matching, and future repairs.
Q3: Does this work for metric measurements?
A: This calculator uses feet. For meters, use the same formula but the result will be in square meters instead of square feet.
Q4: How accurate should my measurements be?
A: For best results, measure to the nearest 1/4 inch and convert to decimal feet (divide inches by 12).
Q5: What if my room isn't a perfect rectangle?
A: For L-shaped or other irregular rooms, break the space into multiple rectangles, calculate each area, then sum them for the total.
