Pig Fencing Calculator
How much fence a paddock actually needs, from its dimensions or from your pig count. Pure geometry — no welfare figure to source — plus an honest note on the one thing it doesn't estimate.
No standard gate width to default to — enter your own; a domestic field gate is commonly 1.2–3.6m.
Fence length needed
40.0m of boundary selected.
How the fence length is worked out
This is geometry, not a welfare standard: enter your paddock's length and width (or estimate a square paddock from your pig count using the RSPCA free-range labelling figures, 12 m² per pig rotated or 40 m² static, the same ones behind our land calculator), tell it which of the four sides actually need new fencing, and it adds them up and subtracts a gate width you enter.
It deliberately doesn't estimate post count. The pig fencing guide already checked for an authoritative source on pig-specific post spacing and found none — only commercial fencing-supplier guidance, which sits well below the government, industry-body and welfare-charity sources the rest of this site is built on. Ask your fence supplier for spacing suited to your ground and fence type.
Pig, for now — this is pig-scoped like the rest of the site's newer tools, though the maths applies to any rectangular paddock.
Common questions
- How much fencing do I need for a pig paddock?
- It's the perimeter of your paddock minus any side that's already fenced, walled or otherwise boundaried, minus your gate width. For a square paddock at the RSPCA figure of 12 m² per pig, four pigs need roughly 28 m of fence in total (all four sides, no existing boundary, no gate) — see the fencing guide for the full table.
- Does this include posts, an energiser or wire?
- No. We couldn't find an authoritative source for pig-specific post spacing, so we don't invent one — the calculator gives fence length only. See the fencing guide for what to buy and the questions to ask a supplier.
- What if my paddock isn't square?
- Enter your actual length and width in "Enter dimensions" mode rather than using the pig-count estimate, which assumes a square paddock. A long, narrow paddock needs more fence than a square one of the same area.
