Frequently asked questions

What is a linear foot?

A linear foot is simply a 12-inch measurement in a straight line. It is the exact same thing as a regular foot. The word "linear" is added in construction and material sales to clarify that only the length matters, regardless of the material's width or thickness.

Does width matter when calculating linear feet?

No. Linear footage only measures the length. Whether you are buying a 2x4 piece of lumber or a 2x12 piece of lumber, an 8-foot board is exactly 8 linear feet in both cases. Width and thickness only matter when calculating board feet or square feet.

How do I convert inches to linear feet?

To convert inches to linear feet, simply divide the total number of inches by 12. For example, a baseboard that is 96 inches long is 8 linear feet (96 ÷ 12 = 8). This calculator automatically performs this conversion if you select "Inches" as your unit.

When should I use linear feet instead of square feet?

Linear feet are used when ordering rolled, extruded, or cut-to-length materials where the width is fixed. Common examples include baseboards, crown molding, fencing, fabric, cabling, and PVC pipes. Square feet are used for 2D surface areas like flooring, drywall, and roofing.

About this calculator

This linear feet calculator helps carpenters, DIYers, and material buyers determine the total straight-line length of an order. Because many materials (like trim, lumber, and fencing) are priced "per LF", knowing your exact linear footage is crucial for accurate budgeting.

The mathematical formulas used by the tool are straightforward conversions:

Total Length = Quantity × Length per Piece

If measured in Inches: Linear Feet = Total Length ÷ 12
If measured in Yards: Linear Feet = Total Length × 3

Total Cost = Linear Feet × Price per LF

A tip on ordering: We strongly recommend adding a 10% waste buffer to your final linear footage calculation. Wood often has split ends, and cutting trim for corners always generates offcuts that cannot be reused. Ordering exactly what the math dictates usually leaves you slightly short.
