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 length = body length + 2 to 4 inches
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.
