Wire fence calculator
Wire rolls = run length plus extra ÷ the roll length, rounded up, times the strands for line wire: a 48 ft run of mesh takes 1 roll of 100 ft, with 2 end posts and 5 line posts.

Common questions
How many rolls of wire fence do I need?
Divide the solid fence length, plus your extra, by the roll length and round up. For strand fencing, multiply the length by the number of strands first.
How many brace posts do I need?
Corners, ends and gates usually take brace assemblies. Enter the count from your plan; the list keeps terminal and line posts separate.
How to plan the quantity
Mesh needs one length along each solid run; strand fencing multiplies that length by the number of strands. Gate openings are excluded from both.
Shared corners and grade changes are counted once by the run topology. Terminal posts stay separate from line posts so the bracing schedule can be checked.
Rolls round after the allowance. Tension, energizers, grounding, attachment details and brace geometry remain system-specific inputs or supplier questions.
Before you order
- This does not choose post depth, wire tension, an animal-containment specification or an electric-fence design.
- Brace counts come from your accepted layout, not an assumed universal rule.
