FOR DECK BUILDERS & CONTRACTORS
Deck Board Calculator
Free lumber optimizer for deck projects. Calculate optimal cuts from standard board lengths to minimize waste on decking, joists, railings, and more. See exactly how many boards to buy.
Stop Wasting Expensive Decking
Composite decking runs $4-10 per linear foot. Pressure-treated lumber keeps climbing. A typical 300 sq ft deck uses 50+ boards—and bad planning can waste 15-20% of your material.
EZNESTING's linear optimizer calculates the most efficient way to cut your required lengths from standard board sizes. Should you buy 12' or 16' boards? How many of each? Where exactly should you cut? Get answers in seconds.
- Reduce lumber waste by 10-20%
- Know exactly how many boards to buy
- Compare costs between board lengths
- Visual cut diagrams for the job site
Deck Components We Optimize
Real Example: 12x16 Deck
See how optimization saves money on a typical residential deck project.
✗Without Optimization
- Buy all 12' boards (easier math)
- Estimate high "just in case"
- ~18% waste on average
62 boards
@ $28/board = $1,736
✓With EZNESTING
- Mix of 12' and 16' boards
- Exact quantities calculated
- ~6% waste optimized
54 boards
@ $28 avg = $1,512
$224 saved on decking alone—before joists, railings, and trim.
Built for Linear Materials
Our 1D optimizer handles lumber, trim, and any material sold by length.
Features for Deck Builders
Everything you need to plan efficient lumber cuts for any deck project.
Linear Optimization
Our 1D optimizer calculates the best way to cut required lengths from standard lumber sizes—8', 10', 12', 16', or 20' boards.
Multiple Stock Lengths
Mix 12' and 16' boards to find the combination with least waste. See exactly how many of each length to buy.
Visual Cut Diagrams
See exactly where to make each cut on every board. Print diagrams to take to the job site or lumber yard.
Kerf Compensation
Account for blade width on each cut. Prevents coming up short on that last piece of every board.
Material Cost Tracking
Enter prices per board length and see total material costs. Compare costs between different lumber combinations.
Works for All Deck Components
Optimize deck boards, joists, rim boards, stair stringers, railings, balusters, and posts—all in one project.
