Calculate linear feet or meters from pieces, mixed lengths, rectangle perimeter, or stock quantities, with optional waste, coverage area, and cost.
A linear foot measures length: one linear foot equals twelve inches. It is not a square foot.
Material width and thickness do not change linear footage, although width can optionally convert length to area.
total length = length per piece × quantityperimeter = 2 × (length + width)planning length = required length × (1 + waste rate)pieces = ceil(planning length ÷ stock length)area = linear length × effective widthTwenty-four 8 ft pieces equal 192 linear ft.
A 20 × 12 ft rectangle has a 64 ft perimeter.
A 135 ft requirement with 10% extra becomes 148.5 ft. With 12 ft stock, buy 13 pieces, providing 156 ft and 7.5 ft surplus.
One hundred linear feet of 6-inch-wide material covers 50 ft².
Twenty 2.4 m pieces equal 48 linear meters.
Width is unnecessary when the question is linear footage.
Every row is converted to meters before totals are combined.
Enter manufacturer-listed effective coverage where overlap, gaps, or exposed face change nominal width.
Stock purchasing does not optimize individual cut allocation or offcut reuse.
An 8 ft board is 8 linear ft regardless of whether it is 2, 4, or 6 inches wide. Its area coverage changes with width.
Multiple rows may mix units. Perimeter mode uses the shared rectangle formula and subtracts only explicit openings.
Waste is applied once to required length before whole stock pieces are rounded upward.
Linear length times effective width gives area. Area divided by effective width gives required linear length.
Stock-piece pricing uses whole pieces. Linear pricing uses purchased length in stock mode and measured length otherwise.
It is a one-foot measurement of length.
Twelve inches.
Yes, when measuring straight length.
Linear feet measure length; square feet measure area.
Multiply each length by quantity and sum the results.
For a rectangle, double the sum of length and width.
Divide waste-adjusted required length by stock length and round upward.
Divide area by effective material width using compatible units.
Not for linear footage; only for area conversions.
No. It is a total-length planning estimate.
Yes. Results include both feet and meters.
