Lumber Calculator
Build a lumber takeoff in board feet, cubic feet, pieces, weight and cost for framing, decking, fencing and roof lumber.
Estimate lumber for a project
Use this lumber calculator as a small takeoff sheet: enter each board size, length, quantity and price to estimate board feet, cubic feet, weight and cost. The intent is closer to a supplier quote or DIY material list than a Russian cubic-meter lumber chart.
Ordering notes
- Separate rows make it easier to mix framing lumber, deck boards, fence pickets and blocking.
- Add waste for cuts, defects, layout changes and rejected boards.
- This is a quantity and cost estimate, not a span, load or structural design check.
