What size crate does my dog need?

2 min readLast reviewed Jun 28, 2026 by JWB

Measuring the right size

  1. Length: measure from nose to base of tail, add 4 inches.
  2. Height: measure from floor to top of head (when standing), add 4 inches.
  3. Width: standard crates are slightly narrower than they are tall; match the height number.
  4. Cross-reference with the manufacturer's breed chart, but trust the measurement for any dog at the edges of breed ranges.

Common sizing mistakes

  • Too big for a puppy: defeats housetraining. They potty in one end, sleep in the other.
  • Too small for an adult: welfare problem. The dog can't change position. Discomfort builds resentment of the crate.
  • Wire vs plastic vs soft-sided: wire (collapsible) is most common and easiest to clean; plastic is required for IATA-compliant air travel; soft-sided is for trained adult dogs only, puppies and chewers destroy them.
  • Bedding choice matters: many dogs eat fleece beds when bored. Start with a low-pile washable mat; upgrade only if the dog leaves bedding alone.
