Square Foot Formula:
From: | To: |
The square foot calculation is a simple mathematical formula used to determine the area of a rectangular space. It's essential for estimating paint coverage, flooring materials, and other surface measurements.
The calculator uses the square foot formula:
Where:
Explanation: The formula multiplies the length by the width to calculate the total area in square feet.
Details: Accurate area calculation is crucial for determining paint quantities, material estimates, and project planning for painting and renovation projects.
Tips: Enter length and width measurements in feet. All values must be valid positive numbers. The calculator will provide the total square footage needed for painting.
Q1: How accurate should my measurements be?
A: For best results, measure to the nearest inch and convert to decimal feet (e.g., 10 feet 6 inches = 10.5 feet).
Q2: Does this account for windows and doors?
A: No, this calculates total wall area. You should subtract non-paintable areas like windows and doors from your final calculation.
Q3: How many square feet does a gallon of paint cover?
A: Typically, one gallon of paint covers 350-400 square feet, but check the manufacturer's specifications on your paint can.
Q4: Should I measure in feet or inches?
A: This calculator uses feet. Convert inches to decimal feet (divide by 12) for accurate calculations.
Q5: Can I use this for multiple walls?
A: Yes, calculate each wall separately and add the results together for the total square footage.
