Linear Feet Calculator
Calculate linear feet for construction projects. Convert feet and inches to decimal feet, add multiple lengths with quantities for material estimating.
About Linear Feet Calculator
Our free Linear Feet Calculator helps contractors, DIY enthusiasts, and homeowners quickly calculate linear feet for construction projects, flooring, fencing, trim work, and any project requiring length measurements. Simply enter measurements in feet and inches to get instant conversions to decimal linear feet. Perfect for estimating materials like lumber, baseboards, crown molding, pipes, and any linear building materials.
This calculator supports both single length calculations and multiple length additions - ideal for projects with multiple pieces of varying lengths. Convert feet and inches to decimal feet instantly, add multiple lengths together with quantities, and get accurate total linear footage for material ordering. The tool works entirely in your browser with instant results and no data transmission, ensuring your project details remain completely private.
Essential for carpenters, contractors, landscapers, and DIYers planning construction projects, renovations, fence installations, deck building, flooring projects, and any work requiring linear measurements. Use it for calculating board lengths, trim pieces, pipe runs, fencing sections, and any linear building materials. Eliminates conversion errors and ensures you order the right amount of materials - saving time and money on every project.
How to Use
- Choose "Single Length" for one measurement or "Multiple Lengths" for several pieces
- Enter measurements in feet and inches (inches are optional)
- For multiple lengths, enter the quantity needed for each size
- Click "Add Length" for each piece, then "Calculate Total" for the sum
- Use the total to order materials - always add 10% extra for waste
Frequently Asked Questions
What is a linear foot?
A linear foot is simply a measurement of length in a straight line, equal to 12 inches. It's commonly used to measure and price lumber, trim, fencing, flooring, and other building materials sold by length rather than area.
How do I convert feet and inches to decimal feet?
Divide the inches by 12 to get the decimal portion. For example, 6 feet 3 inches = 6 + (3/12) = 6.25 linear feet. Our calculator does this automatically for you.
Should I include waste in my calculations?
Yes! Always add 10% extra to your total linear footage to account for cutting waste, mistakes, and off-cuts. For patterned installations or complex layouts, consider 15% waste. Our calculator shows the base amount - add waste factor when ordering.
Can I use this for any material?
Absolutely! This calculator works for any material sold by linear feet: lumber, trim, molding, baseboards, crown molding, pipe, conduit, rope, cable, fencing, and more. Just measure your needed lengths and let us calculate the total.
