What this means

A roughly square shelter would be about 3.1m × 3.1m.

Rectangular options with the same floor area: 3.1m × 3.1m, 2.3m × 4.1m, 1.7m × 5.6m.

Working backwards: how many donkeys fit?

Figures follow The Donkey Sanctuary's guidance for a standard-sized donkey: about 4.7m² of covered bedded area each and at least 0.5 acre of grazing or exercise land each. The shelter must have a roof and three solid sides. A planning guide, not legal advice.
How we calculated this +

Covered bedded area

Applies to:
UK — guidance from the UK's main donkey welfare charity, for a standard-sized donkey
Assumption:
About 4.7m² (50 sq ft) of covered bedded area per donkey, 9.4m² for a pair. The guide adds that donkeys should ideally have more room to move around indoors if they can't go outside.
Calculation:
4.7m² per donkey × donkey count.

Grazing and turnout land

Applies to:
UK
Assumption:
A minimum of 0.5 acre (2,000m²) of suitable and safe grazing and/or exercise area is recommended for each donkey.
Calculation:
2,000m² (0.5 acre) per donkey × donkey count.

Company

Applies to:
UK
Assumption:
Donkeys form close bonds, so the Sanctuary normally rehomes them in pairs or small groups.
Calculation:
A warning shows for a single donkey. It doesn't change the area figures.

Rules can depend on where you live. National welfare requirements aren't the same thing as local planning, registration, nuisance or disease-control rules — check with your local authority before you build or buy.

What this means

The Donkey Sanctuary's stable guide allows about 4.7m² of covered bedded area for each standard-sized donkey. That's room to rest, not to exercise: the guide adds that donkeys should ideally have more space to move around indoors if they can't go outside.

Land is a separate and much larger budget: at least 0.5 acre (2,000m²) of safe grazing or exercise area per donkey, from the Sanctuary's rehoming requirements.

Donkeys form close bonds and are normally rehomed in pairs, so the calculator starts at 2 and warns for a single donkey.

What kind of shelter do donkeys need?
Permanent shelter they can reach at all times, big enough for every donkey, with a roof and three solid sides and hard standing inside and at the entrance. Donkeys' coats don't appear to be as waterproof as horses'.
How high should a donkey stable door be?
The Donkey Sanctuary gives a bottom door height of 3ft 6in (107cm) for standard donkeys, ideally 4ft (122cm) wide. Horse stable doors at 4ft 6in are too high for standard donkeys.
