Formulas Used

First Fit Decreasing

Sort cuts longest → shortest, fit each into first board with room

A bin-packing algorithm that sorts pieces by length (largest first) and places each piece on the first board with enough remaining space. This typically achieves 85-95% material efficiency.

Efficiency

Efficiency = Total Cut Length ÷ Total Stock Length × 100

How much of your purchased lumber actually ends up in your project.

Optimizing Your Cut List

Why Optimize?

A well-planned cut list can save 15-25% on lumber costs by reducing the number of boards purchased and minimizing waste.

Tips for Efficient Cutting

  1. Cut longest pieces first from each board
  2. Group similar lengths to fill boards more efficiently
  3. Account for saw kerf (⅛" per cut)
  4. Buy longer stock — 12ft or 16ft boards often yield better efficiency than 8ft
  5. Label every piece before cutting
  6. Double-check measurements — measure twice, cut once

Stock Length Strategy

| Project Type | Best Stock Length | |-------------|------------------| | Small box/shelf | 6 ft or 8 ft | | Furniture | 8 ft or 10 ft | | Large projects | 12 ft or 16 ft | | Mixed sizes | Buy 2 different lengths |
