Pig Housing tools: what they help with

These calculators size your pig's living space: the minimum and recommended dimensions, how much bedding or substrate to buy and what fits in the space you have. Too little space is one of the most common welfare problems in pets. The right size gives a pig room to move, rest and behave normally.

What to know about housing and enclosure size for pigs

Pigs are highly intelligent and need rooting space, a wallow or shade to manage heat since they cannot sweat, and very strong fencing. They grow far larger than most first-time owners expect. Target humidity is around 40-70%.

A practical tip

Treat the minimum as the floor, not the goal. Bigger is almost always better, especially for active or social species.
