What Is the Dog Kennel Size Calculator?

Calculate the correct kennel or run dimensions for your dog — whether for outdoor boarding, a dog run, or a commercial kennel setup.

A kennel or outdoor dog run must be large enough for the dog to exercise, turn around freely, and exhibit normal behaviour — not just large enough to stand in. This calculator provides minimum kennel dimensions for comfortable long-term use, following RSPCA, UK Animal Welfare Act, and AKC kennel guidelines.

Every result is based on published veterinary research and breed-size-specific growth data — not generic averages. This tool is completely free, works instantly in your browser, and requires no account or sign-up.

How It Works

Kennel size requirements differ from crate sizes — kennels are used for longer periods and must allow movement. The minimum floor area for a single dog in a kennel or run is calculated as at least 4× the dog's body area (body length × width). Height must allow the dog to stand and jump without hitting the roof. Run length should be at least 3× the dog's body length to allow some exercise. These are absolute minimums — larger is always better.

Frequently Asked Questions

What is the minimum legal kennel size for dogs in the UK?+
Under the UK Animal Welfare Act 2006 and associated breeding/boarding regulations, dogs must have sufficient space to stand, turn around, and lie down with legs extended. For commercial boarding kennels, local council licensing sets specific minimum dimensions — typically at least 1.8m × 1.8m for the sleeping area and a separate run of at least 3.6m. Home boarding has different requirements. Contact your local council for current licensed kennel standards.
How long can a dog be left in a kennel?+
The RSPCA recommends dogs are not left alone (in any situation, including kennels) for more than 4 hours without human interaction and exercise. Commercial boarding kennels must provide daily exercise outside the kennel. Prolonged kennelling without enrichment, social contact, and exercise causes significant psychological distress even when physical needs are met.
