Woven Wire Field Fence and Brace Calculator
Calculate woven wire field fence rolls, line posts and corner braces from perimeter and post spacing, with material totals for the run.
How This Calculation Works
Post count equals the perimeter divided by the post spacing, rounded up. Woven wire rolls equal the perimeter divided by the roll length, which is often 330 feet for a standard roll. Corner braces are one per corner, with additional braces on long runs and at gates.

Common Questions
How many rolls of woven wire per mile?
A standard 330-foot roll covers a quarter mile, so a mile needs four rolls. Add extra for gates, corners and waste. Roll length varies by manufacturer, so check the label.
How far apart should woven wire posts be?
Space line posts 10 to 12 feet apart for woven wire, closer than for barbed wire because the wire needs more support. Set corner and brace posts deeper. Uneven ground needs closer spacing.
How do I brace a woven wire corner?
Use a double-post or H-brace with a diagonal brace wire to resist the pull of the tensioned wire. Set the brace posts deep and angle the diagonal correctly. Every corner and gate needs a brace.
Can I use woven wire for cattle?
Woven wire works for cattle, especially where calves or predators are a concern, but it costs more than barbed wire. Add a top strand of barbed wire for strength. Match the wire height to the livestock.
