Convert linear feet (linear ft) to square feet (sq ft) for area calculations. This is useful for estimating materials like flooring, paint, or land area.

Understanding the Conversion: Linear Feet to Square Feet
It's crucial to understand the difference between linear feet and square feet. Linear feet measure length or distance, representing a one-dimensional measurement. For example, the length of a roll of carpet or the perimeter of a room are measured in linear feet.
Square feet, on the other hand, measure area. Area is a two-dimensional measurement, representing the amount of surface covered. To calculate an area, you need two dimensions: length and width (or sometimes length and height, depending on the context).
The formula to convert linear feet to square feet is straightforward for rectangular or square shapes:
Area (sq ft) = Length (ft) × Width (ft)
This calculator is designed for calculating the area of a rectangular or square space when you know its length and width, both measured in feet.
When to Use This Calculator:
Home Improvement Projects: Estimating the amount of flooring (carpet, tile, hardwood), paint, wallpaper, or drywall needed for a room.
Landscaping: Calculating the area of a garden bed, lawn, or patio.
Real Estate: Determining the square footage of a property lot or building.
Construction: Estimating materials for walls, ceilings, or concrete slabs.
Example Calculation:
Imagine you want to carpet a rectangular living room that measures 15 feet in length and 12 feet in width.
Length = 15 ft
Width = 12 ft
Using the formula:
Area = 15 ft × 12 ft = 180 sq ft
Therefore, you would need 180 square feet of carpet for this room. Our calculator can perform this calculation instantly for you.
function calculateArea() {
var lengthInput = document.getElementById("length");
var widthInput = document.getElementById("width");
var resultValueElement = document.getElementById("resultValue");
var length = parseFloat(lengthInput.value);
var width = parseFloat(widthInput.value);
if (isNaN(length) || isNaN(width) || length <= 0 || width <= 0) {
resultValueElement.innerText = "Invalid Input";
return;
}
var area = length * width;
resultValueElement.innerText = area.toFixed(2); // Display with 2 decimal places
