What Is a Linear Foot?
A linear foot is a straight-line measurement of length equal to exactly 12 inches, or one foot. It measures distance in a single dimension. This is the key difference from other common measurements:
Linear Foot: Measures length only (e.g., a 10-foot board).
Square Foot: Measures area (length x width), used for flooring, painting, and land.
Cubic Foot: Measures volume (length x width x height), used for concrete, mulch, and storage.
The fundamental formula for calculating linear feet is straightforward:
Linear Feet = Total Inches / 12
Simple Example: If you have a board that is 72 inches long, the calculation is 72 / 12 = 6 linear feet.
Why Use a Linear Feet Calculator?
Manual calculations are prone to error, especially when dealing with multiple measurements and unit conversions. An online Linear Feet Calculator offers significant advantages:
Saves Time: Get answers instantly instead of adding and converting numbers by hand.
Ensures Accuracy: Automated calculations eliminate human math errors, ensuring your material orders are precise.
Improves Budgeting: With integrated cost-per-linear-foot estimation, you can plan your project finances with confidence.
Reduces Material Waste: By ordering the exact amount of material needed (plus a small waste allowance), you save money and reduce excess.
How to Calculate Linear Feet Manually
Understanding the manual process helps you verify the tool’s results. Let’s calculate the linear feet needed for three sections of baseboard.
Step 1: Measure each piece in inches.
Wall 1: 120 inches
Wall 2: 90 inches
Wall 3: 105 inches
Step 2: Find the total inches.
120 + 90 + 105 = 315 inches
Step 3: Apply the formula (Total Inches / 12).
315 / 12 = 26.25 linear feet
Visual Example:
Total Linear Feet = (120" + 90" + 105") / 12
= 315" / 12
= 26.25 ftOur calculator will yield the same precise result, but without the risk of a miscalculation.
Common Uses of Linear Feet Measurements
Linear footage is a standard unit of measure across numerous industries and projects:
🛠 Home Improvement: Measuring for baseboards, crown molding, chair rails, and trim.
🏡 Construction: Estimating materials for fencing, deck boards, handrails, and pipes.
🛋 Interior Design: Calculating the length needed for curtain rods, shelving, and stair balusters.
📦 Shipping & Logistics: Determining freight charges for long, thin items where space is not the primary factor.

Example Calculation
Let’s walk through a real-world scenario: Calculating Fencing for a Yard.
Imagine you need to build a fence for three sides of your yard.
Side A: 12 feet
Side B: 24 feet
Side C: 12 feet
You enter these three lengths into the calculator. The tool instantly shows:
Next, you enable cost estimation. The fencing material costs $5.50 per linear foot. To account for cutting errors, you add a 5% waste allowance.
The calculator provides a detailed breakdown:
This gives you a clear, accurate budget to present or work from.
FAQs About Linear Feet
How do I convert square feet to linear feet?
You cannot convert square feet to linear feet without knowing the width of the material. The formula is: Linear Feet = Square Feet / Width (in feet). For example, if you have 100 sq ft of flooring and the boards are 2 ft wide, you need 100 / 2 = 50 linear feet.
Is linear feet the same as feet?
Yes, in terms of measurement. A “linear foot” explicitly emphasizes that it is a measurement of length in a straight line, not area or volume.
Can this calculator estimate material cost?
Yes! After entering your lengths, you can toggle on the cost estimation feature, input your price per linear foot, and even add a waste percentage for a comprehensive total.
What projects use linear feet?
Common projects include installing any type of trim (baseboard, crown molding), fencing, decking, handrails, pipes, wires, and fabrics sold by the length.
How accurate are the results?
The calculator’s results are 100% accurate based on the data you input. The accuracy of your final project depends on the precision of your initial measurements.
Expert Tips for Accurate Measurements
Follow these professional tips to ensure your project goes smoothly:
Measure Twice, Cut Once: This old adage is golden. Always double-check your measurements before ordering materials or making cuts.
Account for Waste: Always add a waste factor (typically 5-15%) for projects involving cuts, like flooring or trim, to cover mistakes and off-cuts.
Use Consistent Units: Ensure all your measurements are in the same unit before calculating to prevent errors. Our calculator solves this for you.
Consider Angled Cuts: For trim or molding that meets at corners, remember that angled cuts (miters) require slightly more length than a straight cut.
Use a Quality Tape Measure: A sturdy, reliable tape measure that locks in place is essential for getting consistent numbers.
