4 strands minimum for cattle, 5+ for horses or smaller livestock.

How it works

Multiplies fence length by the number of strands to get total wire length, then divides by roll length to count rolls. T-posts are counted at the chosen spacing.

Formula

Total wire = LF × strands; Rolls = ⌈total wire / roll length⌉
