Dog Crate Size Calculator

Enter your dog's body length (best) or weight for the right crate size in inches.

Reviewed by the 247Sizing teamLast updated: 27 August 2026
A crate should let your dog stand, turn around and lie down โ€” no bigger. Measure body length from nose to base of tail and add about 10 cm. Weight is a handy fallback.

How to measure

  1. Measure length

    From the tip of the nose to the base of the tail (not including the tail).

  2. Add turn-around room

    Add about 10 cm so the dog can stand and turn comfortably.

  3. Don't oversize

    Too large a crate undermines house-training โ€” use a divider for a growing puppy.

  4. Check the door & height

    Make sure the dog can sit without ducking; confirm the model's own chart.

Frequently asked questions

What size crate does my dog need?

Match your dog's weight to the chart above, then double-check with their nose-to-tail body length (not including the tail) โ€” the crate's internal length should be a few cm longer so they can stand and turn comfortably.

Is bigger always better for a dog crate?

No โ€” for crate training, especially with puppies, a crate that's too large can undermine house-training since the dog can use one end as a toilet away from their bed. Size for your dog's current size, or use a divider panel in a larger crate as they grow.

What's the largest dog crate size?

Our chart tops out at 48 inches (XXL), suited to dogs over roughly 40kg with a body length up to about 112cm โ€” the size most giant breeds like Great Danes and Mastiffs need.
