Linear Foot Calculator
Calculate total linear feet, convert area to linear feet, and estimate material cost.
About Linear Foot Calculator
If you’re working on a home improvement project, building a fence, installing flooring, or buying lumber, you’ve probably heard the term “linear foot.” It sounds technical, but it’s actually simple. A Linear Foot Calculator helps you measure length in a straight line, without worrying about width or height.
Unlike square footage, which measures area, linear footage only measures length. This is important when materials are sold by the foot — such as boards, pipes, trim, or fabric.
How to Calculate Linear Feet
The basic formula for linear feet is straightforward:
Linear Feet = Total Length (in feet)
If you’re measuring in inches, convert first:
Linear Feet = Total Inches ÷ 12
Example 1:
If a wall measures 24 feet long, you need 24 linear feet of baseboard.
Example 2:
If you have 300 inches of material:
Linear Feet = 300 ÷ 12 = 25 feet
So 300 inches equals 25 linear feet.
How to Convert Square Feet to Linear Feet
Sometimes materials are measured in square feet, but you need linear feet. In that case:
Linear Feet = Square Feet ÷ Width (in feet)
Example:
You have 200 square feet of flooring that is 2 feet wide.
Linear Feet = 200 ÷ 2 = 100 feet
That means you would need 100 linear feet of that material.
Why Use a Linear Foot Calculator
Measuring by hand is easy for small numbers, but projects often involve multiple sections and conversions. A small mistake can mean buying too little or overspending on extra material.
A linear foot calculator saves time and helps you get accurate totals quickly. It’s useful for contractors, DIY homeowners, and anyone planning construction or renovation work.
Knowing your exact linear footage helps you estimate costs, order materials confidently, and reduce waste. With the right numbers in hand, your project planning becomes much smoother and more organized.
