Use this tool to calculate the total square footage from measurements in both feet and inches.
How to Use the Square Foot Calculator
This calculator helps you determine the area in square feet based on the dimensions you input in feet and inches. Here’s how to use it:
- Input the length in feet and inches in the respective fields.
- Input the width in feet and inches in the respective fields.
- Click the “Calculate” button to see the result in square feet.
How it Calculates the Results
The calculator converts all measurements to inches first (since there are 12 inches in a foot) to perform a precise area calculation. It then follows this procedure:
- Converts feet to inches by multiplying by 12.
- Adds the inches input to the converted feet to get the total length and width in inches.
- Multiplies the total length and width in inches to get the area in square inches.
- Divides the area in square inches by 144 to convert it to square feet, since there are 144 square inches in a square foot.
Limitations
Please note the limitations of this calculator:
- If you leave any input field blank, it assumes a value of zero.
- The maximum value for inches is limited to 11.9, as it represents partial feet.
- The calculator may not handle extremely large values gracefully due to potential floating-point precision issues in JavaScript.
