What this tool does
Convert board-foot volume and linear length using the board cross-section. A thickness and width are necessary: board feet alone cannot specify linear feet.
How to use the Board Feet to Linear Feet Converter
- Enter or select value to convert.
- Enter or select board thickness in in.
- Enter or select board width in in.
- Enter or select direction.
- Read the calculated result; change any measurement to compare alternatives.
Formula
linear feet=board feet×12/(thickness×width); board feet=linear feet×thickness×width/12
- value
- Value to convert
- thickness
- Board thickness (in, before metric conversion)
- width
- Board width (in, before metric conversion)
- direction
- Direction
A thickness and width are necessary: board feet alone cannot specify linear feet.
Worked example
For board feet to linear feet converter, the following measurements illustrate the exact method: Value to convert: 100; Board thickness: 1; Board width: 6; Direction: forward.
Inputs

Results explained
- Linear feet
- Linear feet from the formula above. A thickness and width are necessary: board feet alone cannot specify linear feet.
Frequently asked questions
Divide twelve times board feet by inch thickness and width; reverse by multiplying and dividing by twelve.
Use actual measured thickness and width unless your supplier explicitly prices on nominal rough dimensions. A nominal 2 × 4 is typically 1.5 × 3.5 inches after surfacing.
No unless a waste input is shown. Add stock for end trimming, defects and kerf rather than treating the computed total as a guaranteed cut plan.
Length inputs with a unit can be switched to metric; internal formulas keep a consistent inch/foot basis. Board foot outputs remain board feet.
Changing cross-section changes the equivalent length.
