Input reference and sample values
Use the units and choices shown for each field. Sample values are provided for practice, not as recommendations.
| Input | Format and units | Sample |
|---|---|---|
| Thickness | Numeric value. Unit: in. Must be greater than zero. | 2 |
| Width | Numeric value. Unit: in. Must be greater than zero. | 6 |
| Length | Numeric value. Unit: ft. Must be greater than zero. | 8 |
| Number of boards | Whole numbers only. Minimum: 1. Maximum: 100000. | 10 |
Result for these sample inputs
80 board ft
Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Board feet = thickness(in) × width(in) × length(ft) × count/12.
Using thickness = 2 in, width = 6 in, length = 8 ft, number of boards = 10, the result is 80 board ft. Change these example inputs to match your task; use the method above to check each step.
What to keep in mind
Use actual dimensions or nominal dimensions according to your purchasing convention. A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.
