About this tool
Use tool ↑Plan rolls for a fencing installer’s independent wire runs.
Enter each net run after removing gates. Apply the same strand count to every run. Add an allowance at both ends of each strand, then waste, and round total stock up to whole rolls. Assume offcuts can be joined or reused.
- Enter your values

Frequently asked questions
Does it calculate posts or braces?
No. Structural assemblies, tension, sag and splice suitability need separate design and manufacturer instructions.

- Measurement system
The initial choice follows your browser region. Your choice is remembered on this device. Gallons are US gallons. Switching units keeps your numbers unchanged and interprets them in the new unit.
Numbers stay unchanged. Check the new unit and enter the intended measurement, or select an example for that system.
- Independent wire runs
Enter one item per row; each column describes that item.
- Net run length, excluding gates
Enter each net run after removing gates.

Common mistakes and quick fixes
Net run length, excluding gates · Wire length per roll · Extra wire at each end
Mistake: Changing units and assuming the entered numbers were converted.
Fix: Numbers stay unchanged. Check the new unit and enter the intended measurement, or select an example for that system.
Does it calculate posts or braces?
Mistake: Treating a result as valid outside the described scope.
Fix: No. Structural assemblies, tension, sag and splice suitability need separate design and manufacturer instructions.
Limits and key assumptions
- No. Structural assemblies, tension, sag and splice suitability need separate design and manufacturer instructions.
- Assume offcuts can be joined or reused.
- Displayed results may be rounded; rounding does not add measurement precision.
