What is the Goose Run & Pasture Size Calculator?
The Goose Run & Pasture Size Calculator calculates minimum outdoor run or pasture space needed per head for geese. Undersized housing is one of the most common and most fixable welfare problems in pet keeping, it affects everything from stress levels to exercise to litter/waste management.
Geese generally live 15-25 years when they are well looked after. Diet-wise they are an omnivore, which shapes almost every feeding decision you make. Geese are grazers that get most of their diet from grass, and need a large area plus water deep enough to dip their heads. They are loud, territorial and make effective guard animals, but a gander can be genuinely aggressive in breeding season. The usual suspects for this species are angel wing from high-protein feed, bumblefoot, egg binding, so any noticeable change is worth following up.

How does the Goose Run & Pasture Size Calculator work?
The recommendation is based on published care-guide minimums for geese, scaled to the animal's current or expected adult size. It is a starting point, not a verdict. Somebody who has actually examined your goose will always know more than a formula does.
Factors that matter
- Adult size: housing should be sized for the animal's full-grown dimensions, not its current size if still young
- Number of animals being housed together, since space needs don't simply divide evenly
- Activity level and natural behavior, such as climbing, digging or swimming space
- Whether the space is temporary (travel/carrier) or permanent (everyday housing)
How do you use the Goose Run & Pasture Size Calculator?
- Enter the adult weight in whichever unit you use (lb, oz, kg)
- Enter the nose-to-tail length in whichever unit you use (in, ft, cm)
- Answer "How many animals share this space?"
- Pick your time spent in the enclosure (Only to sleep, Part of the day, Most of the day, ...)
- Press Calculate, then read the result alongside the sources listed below
If two people care for your goose, agree on one method and stick to it. Half of all confusing results come from measuring differently each time.

Before you rely on this
Two geese with identical numbers on paper can still need different care. Breed or line, body condition, activity level and any existing health conditions all pull the real answer away from the average. If your goose has a diagnosed condition, is pregnant, or is very young or very old, treat the figure here as the loosest of guides and let your vet set the actual target.
