Estimate boards, required and purchased linear length, physical volume, board feet, waste, and material cost for one size or a mixed lumber list.
Piece rows apply waste once to quantity before rounding upward. Linear rows apply waste once to required length before dividing by stock length.
All actual dimensions are normalized before physical volume and the shared Board Foot utilities calculate board feet.
boards = ceiling(quantity × (1 + waste %))boards = ceiling(required length × (1 + waste %) ÷ stock length)actual thickness × actual width × total lengthphysical volume converted with 1 board foot = 1/12 cubic footTwelve 2 × 8 × 10 ft boards total 120 linear ft and 160 base board feet. At 10% extra, buy 14 boards: 140 ft and about 186.67 purchased board feet.
For 100 linear ft using 12 ft stock, 10% extra recommends 110 ft. Exact need is 9.17; buy 10 boards for 120 ft with 10 ft leftover.
Values are never silently translated from nominal labels.
Stock length choices are estimating assumptions, not supplier guarantees.
The calculation does not optimize cuts, kerf, or offcut reuse.
Base totals describe the entered need. Purchased totals use whole stock boards after waste and rounding.
Each row may be priced per board, purchased linear unit, or purchased board foot. Tax, delivery, labor, hardware, milling, and finishing are excluded.
Enter actual thickness and width. No nominal preset or market-specific conversion is assumed.
This estimator does not select member sizes, spans, spacing, species, grades, connections, or code requirements.
Enter each size by pieces or required linear length, choose stock length and waste, then use the rounded purchase totals.
Divide recommended length after waste by stock length and round upward.
It is a volume equal to 144 cubic inches, or one-twelfth cubic foot.
Linear feet measures length; board feet measures volume using thickness, width, and length.
Use actual dimensions for accurate volume and board-foot results.
Yes. Lumber List mode supports independent piece or linear rows.
No. It estimates stock quantity without cut-pattern, kerf, or offcut optimization.
No. Member selection must come from the project design.
