Deer fence mesh is often sold in rolls of about 100 ft. Deer fences are usually at least 6 ft tall, often higher.
How wire is counted
Wire = fence length × strands. Rolls = wire ÷ roll length, rounded up. Posts = length ÷ spacing + 1 on each run, with bracing at every end, corner and gate.
Example: 400 ft with 1 strand needs 400 ft of wire, or 4 rolls of 100 ft, and 35 posts at 12 ft spacing.

Four or five strands is common for cattle. Do not use barbed wire for horses.
