How to choose the right crate size
A crate should be large enough for your dog to stand up, turn around and lie down comfortably, and no larger. Too big and a puppy may toilet in one corner and sleep in the other, which slows house training.
Measure your dog from the tip of the nose to the base of the tail, and from the floor to the top of the shoulders. Add about 4 inches (10 cm) to each, then choose the next standard crate size up. For puppies, buy the adult size and use a divider, then move it back as your puppy grows.

Answers
Frequently asked questions
What size crate do I need for a puppy?
Choose a crate that fits your puppy’s adult size and use a divider while they are small. Standard sizes run from 18 to 48 inches long.
How do I measure my dog for a crate?
Measure from nose to base of tail and from floor to shoulders, then add about 4 inches to each and pick the next standard size up.
Can a crate be too big for a puppy?
Yes. A very large crate can encourage toileting in one corner. A divider keeps the space snug during house training.
How long can a puppy stay in a crate?
Young puppies need breaks every one to three hours in the day and often a toilet trip overnight. The time grows with age. Ask your vet for guidance.
Is the Puppy Crate Size Calculator free to use?
Yes. The Puppy Crate Size Calculator is completely free, needs no sign-up and works on phones, tablets and computers.
Can I rely on the Puppy Crate Size Calculator instead of my vet?
No. It gives a general starting point based on published guidance. Every puppy is different, so always follow your own vet’s advice.
