Little land per pig, lots of land per year
Measured by the animal, pigs are the most economical grazers in this category: a small batch of growing pigs thrives on a quarter-acre paddock, rooting, grazing and exploring ground that would look cramped for almost any other livestock. The number misleads if you stop there, because pigs do not so much graze land as renovate it. A snout is a plough: within weeks a stocked paddock is turned soil, and within a season it can be bare, compacted earth that grows nothing. So the true land requirement is not the paddock the pigs stand in but the paddocks — plural — that let you move them off and rest the ground until grass re-establishes. Two batches' worth of ground, rotated, is the honest minimum for keeping growers outdoors year after year, and breeding sows with litters need more room again, plus ground you can afford to sacrifice entirely around the farrowing shelter.
What pig ground has to provide
Pigs cannot sweat, which makes shade and a wallow welfare requirements rather than comforts: every paddock needs tree cover or a shade structure, and a mud wallow the pigs can coat themselves in against heat and sunburn. The shelter itself can be simple — an arched hut or a deep-bedded stable corner — as long as it is draught-free and dry, because pigs feel cold badly at night even while they overheat at noon. Site the hut and the feeding area on the highest, best-drained ground in the paddock, and expect both to need moving or re-bedding as the pigs rework the soil around them; rings or frequently shifted feeding spots spread the damage. Water must be heavy-duty: a pig drinks a lot, plays in more, and will upend any trough it can, so fixed or weighted drinkers belong in the land plan.
Fencing that teaches, not just fences
Pigs are strong, clever and motivated, and conventional stock fencing alone is an invitation: a pig pushes under, lifts with the snout and walks through gaps that stop bothering it once tested. The standard answer is a low electric strand at nose height inside the boundary, which teaches pigs in a single lesson to respect the fence line itself; after that education, even modest fencing holds them, because they stop testing it. Gates get the same treatment, and the whole perimeter earns a regular walk, since a pig finds a weak point the day it appears. Ground choice helps too: pigs root less destructively on light, free-draining soil and turn heavy clay into a quagmire that takes a full season to forgive.
Plan the acreage, then plan for the escape
Put together, the pig plot that works is a rotation: two or more secure paddocks, a dry hut site, shade and a wallow in each section, and fencing the herd has learned to respect. Keep numbers matched to the wettest month, not the driest — winter is when pig ground fails, and a paddock that carried six growers gloriously in July can be a welfare problem in January. And since even good systems have an off day, think ahead about recovery: if a pig pushes out through a damaged fence, KinsLe's Lost Pet Alert System sends an alert to nearby members straight away, and whoever finds your pig can message you directly through that alert, which shortens the gap between a pig at large and a pig back in its paddock considerably.
