Linear Feet Calculator
Use this free linear feet calculator to find the total linear feet of any material fast. Calculate from a number of pieces and their lengths, or convert square feet and board width into linear feet for flooring, trim, fencing, and lumber. It takes the guesswork out of measuring so you order the right amount every time.
How to Use the Linear Feet Calculator
Linear feet simply means the total length of material, measured in a straight line. Choose how you want to calculate: from a number of pieces and their length each, or from an area and the width of your boards. The calculator gives you the total linear feet instantly.
What Are Linear Feet?
A linear foot is one foot of length, regardless of width or thickness. It is how lumber, trim, fencing, and flooring are often sold. Linear feet differ from square feet, which measure area, so it is important to use the right one when ordering materials.
Frequently Asked Questions
How do I calculate linear feet?
Add up the length of all your pieces in feet. For boards covering an area, divide the square footage by the board width in feet to get linear feet.
What is the difference between linear feet and square feet?
Linear feet measure length only, while square feet measure area (length times width). Materials sold by length use linear feet.
How do I convert square feet to linear feet?
Divide the area in square feet by the width of your board in feet. Switch this tool to the area mode and it does the conversion for you.
Do linear feet account for width?
No. Linear feet measure length only, so a 6-inch board and a 12-inch board of the same length are the same in linear feet.
