Price Per Linear Foot Calculator

A linear foot is just a foot of length, measured along one direction, no matter how wide or thick the thing is. Plenty of building materials are sold this way: fencing, lumber, gutters, baseboards and trim, countertops, pipe, and fabric, which is often quoted by the running foot or running yard. Price per linear foot is what lets you compare two of them or budget a run before you buy.

The math is plain. Divide the total price by the length in feet to get the price per linear foot. Enter a total and a length here and the calculator returns that rate, then also breaks it down to price per inch and price per yard, which helps when a supplier quotes in different units. If you type in the length you actually need, it projects what that run will cost at the same rate.

Here is the trap with linear-foot pricing, and it catches people constantly. It ignores width and thickness entirely. A countertop quoted at 40 dollars per linear foot might be 25 inches deep or 30 inches deep, and the wider slab gives you more material for the same number. When two products come in different widths, comparing them by the linear foot is misleading, so convert to price per square foot instead, which folds the width back in.

For anything sold in a single standard width, like a specific fence panel, a gutter profile, or a trim molding, linear-foot pricing is exactly the right tool and the comparison is fair. That is most of the time, which is why the unit is so common at the lumberyard.
