Linear Feet Calculator
Convert a coverage area into linear feet of boards.
Enter the area you need to cover and your board width to get the total linear feet of material, plus how many boards of a given length that works out to. Useful for decking, flooring, fencing, and trim.
How it works
Linear feet is the running length of material regardless of width. To cover an area, divide the area by the board width in feet (board width in inches ÷ 12). Divide the result by your board length to get the number of boards.
Frequently asked questions
How do I convert square feet to linear feet?
Divide the area by the board width in feet (board width in inches ÷ 12). 100 sq ft of 5.5-inch boards is about 218 linear feet.
What is the difference between linear and square feet?
Linear feet measure length only; square feet measure area. Boards are often priced by the linear foot but installed to cover an area.
How many boards is that?
Divide the linear feet by your board length and round up. 218 linear feet in 8-ft boards is about 28 boards.
