Dog Crate Size Calculator
Enter your dog's measurements to find the right standard crate size. The crate should be big enough for your dog to stand, turn around, and lie down comfortably.
How It Works
The sizing rule is simple: add 2-4 inches (5-10 cm) to both the body length and shoulder height. Then match to the nearest standard crate size that meets or exceeds both dimensions.
Minimum crate height = shoulder height + 2 to 4 inches
→ Round up to the nearest standard crate size

Understanding Your Results
Too small: If the crate is too small, your dog cannot stand up fully or turn around. This causes stress and is not safe for extended crating.
Too big: For house-trained adult dogs, a slightly larger crate is fine. For puppies being house trained, excess space may encourage accidents. Use a divider.
Deep-chested breeds (Greyhound, Whippet, Boxer) may need a taller crate than their weight suggests. Always measure height, not just weight.
Frequently Asked Questions
How do I measure my dog for a crate?
Body length: measure from the tip of the nose to the base of the tail (not the tip). Shoulder height: measure from the floor to the top of the shoulders (withers) while standing. Add 2-4 inches to each measurement for the minimum crate dimensions.
What if my dog is between two crate sizes?
Always go with the larger size. A crate that is slightly too big is better than one that is too small. You can use a divider panel to reduce the space for house training and remove it as the dog grows.
Should I get a bigger crate for a puppy?
Yes, buy a crate for their expected adult size and use a divider to section off the extra space. This prevents the puppy from using one end as a bathroom and saves you from buying multiple crates.
What are the standard crate sizes available?
Most manufacturers offer crates in these lengths: 18", 22", 24", 30", 36", 42", and 48". Some brands also make 54" crates for very large breeds. The sizes correspond roughly to breed size categories from toy to giant.
