What is linear feet to square feet?
Linear feet measure length along a single dimension, while square feet measure area. Materials such as flooring planks, fabric, lumber, and rolled goods are often sold by the linear foot at a fixed width. To find how much area a given run of material covers, you multiply its length by its width.
This calculator takes a length in linear feet and a width in feet, then returns the covered area in square feet.
Formula
Both the length and the width must be expressed in feet so that the result comes out in square feet (ft²).
How to use
- Enter the length of material in the Linear feet field.
- Enter the material’s Width in feet.
- Read the area in square feet from the Square feet output. It updates automatically once both values are present.
Worked example
Suppose you have 10 linear feet of a material that is 2 feet wide:
So the material covers 20 square feet.
For a narrower roll, take 12 linear feet at a width of 0.5 feet:
That run covers 6 square feet.
FAQ
Why does the width need to be in feet? Square feet are the product of two measurements in feet. If your width is given in inches, divide it by 12 to convert it to feet before entering it (for example, 6 inches = 0.5 feet).
How is this different from total square footage? This tool assumes a single continuous run of one fixed width. If you need to add up several rectangular areas or different room sizes, use the Square Footage calculator. To work in metric units, try the Square Meters calculator.
