Whether you’re working on home renovation, construction, or material estimation, understanding linear feet is essential. From ordering lumber and piping to buying carpet or fencing, many materials are sold and measured by linear feet. To make your life easier, we offer the Linear Feet Calculator, a quick and accurate tool to convert measurements and estimate total length in linear feet.
What Is a Linear Foot?
A linear foot is simply a 12-inch (1-foot) measurement of length in a straight line. It doesn’t account for width, height, or depth—only length. The term is widely used in construction, lumber, flooring, fencing, fabrics, and piping.
Key Point:
Linear feet = feet in a straight line, no matter how wide or thick the material is.
What Does the Linear Feet Calculator Do?
The Linear Feet Calculator is designed to:
- Convert inches, feet, or yards into linear feet
- Multiply quantity by individual lengths
- Help estimate material needs
- Avoid waste and over-ordering
- Simplify measurements for planning and cost estimation
It’s perfect for homeowners, DIYers, contractors, interior designers, and architects.
How to Use the Linear Feet Calculator
Step-by-Step Guide:
- Enter Quantity
Input how many pieces or items you have. - Enter Length of Each Piece
Provide the length of each item in feet, or enter inches and the calculator will convert it for you. - Click Calculate
The calculator adds all the lengths and shows the total in linear feet. - Optional Add-ons
Some versions of the calculator allow you to add width or convert to cost estimates based on price per linear foot.
Formula Used in Linear Feet Calculation
Here are the plain text formulas used by the calculator:
Single Item:

mathematicaCopyEditLength in Feet = Length in Inches ÷ 12 Cost Estimation (Optional):
mathematicaCopyEditTotal Cost = Total Linear Feet × Price Per Linear Foot Example Calculations Using the Tool
Example 1: Lumber Purchase
You need 20 boards, each 8 feet long.
javaCopyEditTotal Linear Feet = 20 × 8 = 160 linear feet Example 2: Carpet Trim in Inches
You have 6 trim strips, each 96 inches long.
Convert inches to feet:
javaCopyEdit96 ÷ 12 = 8 feet Total Linear Feet = 6 × 8 = 48 linear feet Example 3: Fence Installation
You plan to install 100 ft of fence, but you have to buy it in 6-ft sections.
javaCopyEditRequired Sections = 100 ÷ 6 ≈ 16.67 → You’ll need 17 sections Total Linear Feet = 17 × 6 = 102 linear feet Common Uses for Linear Feet Calculations
- Lumber & wood planks
- Fencing
- Wiring & piping
- Flooring and baseboards
- Fabric rolls and textiles
- Metal rods or rebar
- Crown molding and trims
- Decking material
- Shelving and cabinetry
Benefits of Using the Linear Feet Calculator
- Saves Time: Instantly calculates lengths without manual math.
- Reduces Waste: Helps avoid over-ordering materials.
- Improves Budgeting: Easily determine material cost using price per linear foot.
- Ensures Accuracy: Perfect for bids, quotes, and supply lists.
- User-Friendly: No technical knowledge required.
Helpful Tips When Calculating Linear Feet
- Measure Twice: Always double-check measurements before buying.
- Round Up: Always round up to avoid material shortages.
- Include Waste Factor: Add 5–10% extra for cuts, mistakes, or spares.
- Account for Joint Gaps: For fences or wood floors, gaps may change total length needed.
- Label Units Clearly: Don’t confuse linear feet with square feet or cubic feet.
Frequently Asked Questions (FAQs)
1. What is the difference between feet and linear feet?
They are the same in terms of length, but "linear feet" emphasizes straight-line distance.
2. How many linear feet are in a foot?
One foot equals one linear foot.
3. How do I convert inches to linear feet?
Divide the number of inches by 12.
4. How is linear feet different from square feet?
Square feet measures area (length × width), while linear feet only measures length.
5. Is width considered in linear feet?
No, linear feet only consider length.
6. How do I calculate linear feet for flooring?
Measure the length of each plank and multiply by the number of planks.
7. Can I use this calculator for fabric?
Yes, fabric is commonly sold by the linear foot.
8. What if the item is curved?
Linear feet still measures end-to-end length in a straight line.
9. How do I estimate price using linear feet?
Multiply total linear feet by cost per foot.
10. Is a board foot the same as linear foot?
No. Board feet consider volume (length × width × thickness), while linear feet is just length.
11. Can I add multiple lengths?
Yes, just enter each separately and sum the total linear feet.
12. Does the tool handle metric units?
Most are in feet and inches, but some calculators also support meters.
13. Can I use this for piping?
Yes, linear feet is commonly used in plumbing and piping.
14. Do I need to convert width or height?
Not for linear feet—only length matters.
15. What’s the best way to measure an object’s length?
Use a tape measure or laser measuring tool for precision.
16. Is linear foot the same as running foot?
Yes, "running foot" and "linear foot" are used interchangeably.
17. How do I round off my result?
Round up to the nearest whole number to avoid shortage.
18. Can this calculator estimate shipping dimensions?
Yes, it can help with estimating the length component of freight or packaging.
19. Is it used in real estate or home appraisals?
Not typically; real estate uses square footage.
20. Can I calculate cost per linear foot manually?
Yes. Just divide total cost by number of linear feet.
Conclusion
The Linear Feet Calculator is an essential tool for anyone working with length-based materials. Whether you’re laying carpet, building a deck, or installing a fence, this calculator provides fast and accurate estimates. It helps prevent costly mistakes and ensures you get exactly what you need—no more, no less.
