Square Footage Formula:
| From: | To: |
Square footage is a measurement of area expressed in square feet. It represents the total floor space of a room or building and is commonly used in real estate, construction, and interior design to quantify space.
The calculator uses the basic area formula:
Where:
Explanation: For rectangular rooms, simply multiply the length by the width to get the total square footage. This formula works for any rectangular or square-shaped space.
Details: Accurate square footage calculations are essential for determining material quantities for flooring, carpeting, painting, and tiling. It's also crucial for property valuation, rental pricing, and space planning in interior design.
Tips: Measure the length and width of your room in feet using a tape measure. Enter both measurements in the calculator. Ensure measurements are taken at floor level and account for any irregularities in room shape.
Q1: How do I measure irregularly shaped rooms?
A: For irregular rooms, divide the space into rectangular sections, calculate each section separately, then sum the areas.
Q2: Should I include closets and alcoves?
A: Yes, include all permanent floor space. Measure closets and alcoves separately and add them to the main room area.
Q3: What's the difference between square feet and square meters?
A: Square feet is the imperial unit (1 sq ft = 0.0929 sq m), while square meters is the metric unit. This calculator uses square feet.
Q4: How accurate do my measurements need to be?
A: For most purposes, measurements to the nearest inch (or 0.1 feet) are sufficient. For precise material ordering, measure to the nearest 1/4 inch.
Q5: Can I use this for triangular or circular rooms?
A: No, this calculator is for rectangular spaces. For triangles use A = ½ × base × height, for circles use A = π × radius².
