Formula Used
  1. Straight length: sum of all straight segments.
  2. Arc length: \( L_{arc} = r \times \theta \), where \( \theta \) in radians. With degrees: \( L_{arc} = \pi \times r \times \frac{\text{deg}}{180} \).
  3. Subtotal: straight + arc.
  4. After gaps: subtotal − sum(gaps).
  5. After waste: after gaps × (1 + waste%).
  6. Overlap: joints × overlap. Joints ≈ packs − 1; packs = ceil((after waste + overlap)/pack length). Iterate until stable.
  7. Final length: after waste + overlap.
  8. Spikes: ceil(final length / spike spacing).
  9. Connectors: max(packs − 1, 0) + extra connectors.

All math done in selected units. Conversions: 1 ft = 12 in; 1 m ≈ 3.28084 ft.

How to Use
  1. Choose units (feet/meters) with the toggle.
  2. Add segments: use Straight for runs, Arc for curves.
  3. Add gaps (gates/driveways) to subtract from perimeter.
  4. Set waste, spike spacing, pack length, and overlap.
  5. Press Calculate to view length, packs, spikes, connectors.
  6. Export summary via CSV or PDF.

Tip: break complex shapes into multiple short straights and arcs.

FAQs

Arc length uses radius and angle for geometric precision. For irregular bends, use multiple smaller arcs approximating the curve for improved accuracy.

Many installers use 5–10% depending on complexity and material flexibility. Intricate layouts, tight radii, or rigid materials may require more allowance.

Joints are the pack meeting points and equal packs minus one. Overlap per joint is added. Connector count equals joints plus any extra connectors you specify.

Enter feet with decimals (e.g., 6.5 ft). For inches, convert to feet by dividing by 12, or switch to metric and enter meters.

Corners are represented as short straights or arcs. If special corner connectors are required, include them under extra connectors to ensure adequate fittings.
