Horse Housing tools: what they help with

These calculators size your horse'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 horse room to move, rest and behave normally.

What to know about housing and enclosure size for horses

Horses need roughly one to two acres of grazing per animal, shelter from wind and sun, companionship of other horses, and near-constant access to forage since their stomachs are built for trickle feeding. 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.

Housing tools for other pets

The same kind of tool exists for other species, each using that animal's own reference data: pony housing, donkey housing, goat housing and sheep housing.
