About this calculator
For two medium rabbits, this scenario uses the RSPCA UK reference of at least 3 m × 2 m × 1 m total living space, including shelter and exercise area. Shelter dimensions are a planning split, not the entire housing requirement. Larger breeds and groups may need more space; check local welfare guidance and ensure both areas allow natural movement.
Worked example
calculated with the default values below
Number of rabbits 2 Shelter length estimate 6.6 ft · Shelter depth estimate 3.3 ft · Shelter height reference 2.5 ft · Exercise area estimate 43 sq ft · Total living area reference 64.6 sq ft
Method and assumptions
A = 64.6 ft² × ceil(rabbits ÷ 2); shelter reference = 6 × 2 × 2 ft per pair For two medium rabbits, total living area reference = 3 m × 2 m = 6 m² (64.6 sq ft) with 1 m height, including shelter and exercise. Shelter/run split and scaling for additional pairs are illustrative, not official minimums; larger breeds and groups may require more. Reference: RSPCA UK.

Frequently asked questions
Is a small hutch enough for a pair of rabbits?
No. This calculator uses the RSPCA UK reference for a pair of medium rabbits: at least 3 m × 2 m × 1 m overall living space, including shelter and exercise. The calculated shelter/run split is only a planning scenario; larger breeds and groups can require more. Check local welfare guidance and the [RSPCA housing advice](https://www.rspca.org.uk/adviceandwelfare/pets/rabbits/environment).
Is this a universal minimum enclosure standard?
No. Welfare guidance differs by location and rabbit size. Use the dimensions as a planning reference and check current guidance from a reputable local animal-welfare organization; rabbits need ongoing access to exercise space.

What is a complete worked example for Number of rabbits = 2?
Inputs: Number of rabbits = 2. Calculation: A = 64.6 ft² × ceil(rabbits ÷ 2); shelter reference = 6 × 2 × 2 ft per pair. Results: Shelter length estimate = 6.6 ft; Shelter depth estimate = 3.3 ft; Shelter height reference = 2.5 ft; Exercise area estimate = 43 sq ft; Total living area reference = 64.6 sq ft.
