All lengths support in / ft / mm / cm.
Presets set stick length/unit, kerf, waste, and available profiles. Verify against current catalogs.
Common: 36, 72, 78, 94/96 inches, or 2.5m.
%
Covers mistakes, defects, color matching, and layout.
Typical kerf ~ 1/8 in (3.175 mm).
cuts/piece
Approximate cuts per individual piece produced.

Formulas Used
- Unit normalization: All lengths converted to feet for internal math.
- Pieces per opening: Opening length × pieces.
- Total kerf loss: Total pieces × cuts per piece × kerf per cut.
- Net length: Sum(piece lengths) + total kerf loss.
- Waste addition: Net length × (waste% ÷ 100).
- Total length: Net length + waste addition.
- Usable per stick (advanced): stick − start trim − end trim.
- Sticks required: ceil( total length ÷ usable per stick ).
Assumptions: straight pieces; adjust waste/cuts for miters, scribing, or fragile materials. Catalog presets are approximate—verify with current manufacturer data.
How to Use This Calculator
- Pick a Manufacturer / Catalog preset or keep Generic, then adjust fields.
- Set Stick length, Waste, Kerf, and Cuts per piece.
- Add rows for each opening; choose Profile, Length, Unit, and Pieces.
- Lock Profile Units to control summary/optimization display units.
- Enable the advanced solver and configure trims, per‑piece add, and max pieces.
- Click Calculate, then export results as CSV or PDF.
- Use Copy Shareable URL to save or share the entire setup.
FAQs
T-Molding, Reducer, End Cap, Threshold, and Stair Nosing. Presets may limit profiles to match typical catalog offerings.
They’re conservative starter values based on common lengths and practices. Confirm specifications against the current manufacturer catalog before ordering.
It accounts for start/end trims per stick, per‑piece trim adds, kerf per cut, and optionally limits pieces per stick. It uses decreasing‑order packing heuristics to minimize sticks and leftover.
Without optimization, we divide totals by stick length. With optimization on, we count sticks from the computed plan, using usable length per stick after trims.
Yes. Each row accepts its own unit. The calculator normalizes internally and shows results by your stick unit and profile unit locks.
It’s a high‑quality heuristic (FFD/BFD). For exact solutions or multi‑objective constraints, export CSV to specialized cutting‑stock software.
