Dog Crate Size Calculator
Measure your dog standing up, then enter the numbers. You'll get the smallest standard crate your dog can stand, turn and lie down in.
How the calculation works
Add 4 inches to your dog's length and height. The crate's inside length and height should be at least that much. Crates are sold by their length, so the calculator picks the shortest standard size that is long and tall enough.

Frequently asked questions
Can a crate be too big?
For house training, yes. Puppies will often soil one end of a crate that's much bigger than they need. Buy the adult size with a divider panel and move it back as your puppy grows. Our puppy weight calculator can estimate adult size.
Wire, plastic or soft crate?
Wire crates fold flat and give good airflow. Plastic crates feel more den-like and are usually required for air travel. Soft crates are light for trips but easy for a determined dog to chew through.
