Dog Crate Size Calculator — find the right fit 📦

Two quick measurements and we'll match your dog to a standard crate size (18"–54") — snug enough to feel like a den, big enough to stand, turn and lie down.

30"

Measure standing, from the tip of the nose to where the tail meets the body (not the tail tip).

20"

Floor to the top of the shoulders (withers), standing.

🐾 Puppy tip: buy the crate for your dog's expected adult size and use a divider panel to shrink the space while they grow. One crate, no re-buying — and the smaller space still supports house training. (Measure a parent, or use our Puppy Weight Calculator to estimate adult size.)

The right crate lets your dog stand up, turn around and lie down — and not much more. Too big undermines house training (dogs will potty in one corner and sleep in the other); if in doubt, size up and add a divider. Method: crate length ≈ dog length + 2–4", crate height ≈ standing head height (shoulder + ~25% for the head and ears) + 2–3". Wire-crate dimensions vary a little by brand — double-check the listing.
