Formulas Used
Plywood sheets
- Panels along length = ceil(L_eff / Wp_eff)
- Rows along height = ceil(H_eff / Hp_eff)
- Sheets per face = cols × rows
- Total sheets (gross) = sheets_face × faces
- Adjusted = ceil(gross × (1 + waste%) / reuse)
Studs
- Studs per face = floor(L_eff / S) + 1
- Total studs = studs_face × faces × (1 + extra%)
- Stud linear length = total_studs × H_eff
Edge fasteners
- Perimeter per face = 2(L_eff + H_eff)
- Vertical seams = (cols − 1) × rows × Hp_eff
- Horizontal seams = (rows − 1) × cols × Wp_eff
- Edge length = sum above; fasteners = edge_length / spacing_edge
Field fasteners
- Area per face = L_eff × H_eff
- Fasteners ≈ area / spacing_field² (same units)
Cut‑List
- Effective cut length = stud_length + allowance
- Pieces per board ≤ (stock + kerf) / (cut + kerf)
- Waste = stock − (pieces × cut + kerf × (pieces − 1))
Notes: Equal-length stud cuts are assumed. This greedy planner targets either minimal board count or minimal waste per board.
How to Use
- Select your unit system and confirm default panel size.
- Enter wall length, height, and choose faces (one- or two-sided).
- Pick panel orientation and stud spacing to match your practice.
- Optionally set waste, reuse, and edge trim allowances.
- Choose a stud size preset, select stock lengths, set kerf and allowance.
- Click Recalculate to view sheets, studs, fasteners, and the cut list.
- Use Download CSV or Download PDF for submittals and purchasing.
FAQs
Common panels are 4×8 ft or 1200×2400 mm. Adjust to match inventory or system formwork modules.
This tool focuses on face plywood and vertical studs. Walers, ties, braces, and shores are excluded.
Fasteners are approximated from seam length and field spacing. Always verify against project specifications for edge and field patterns.
If panels are reused across segments in the same pour sequence, divide the gross sheet count by reuse to estimate purchases.
Choose the orientation that minimizes rows and seams while aligning with stud direction and structural requirements.
Openings are not separately modeled. Use the waste and extra stud allowances to offset simplifications.
You can select a strategy: minimize boards or minimize waste. The algorithm packs equal‑length stud cuts into your chosen stock lengths using a simple greedy method.
