Dog Crate Size Finder
Most crate size charts make you guess from weight alone — but a 65-pound Greyhound and a 65-pound Bulldog need completely different crates. The right size comes from your dog’s actual body: length, height, and weight together.
This free finder does the math the charts skip. Pick your breed (or enter measurements manually), tell us if your dog is still growing, and get the exact standard crate size — 18″ through 48″ — with divider guidance for puppies and crates to buy in your size on Amazon.
What Size Crate Does My Dog Need?
Three quick inputs beat the weight-only guess. Pick your breed to pre-fill typical adult measurements, or measure your own dog with the diagrams below.
Breed (optional — pre-fills the numbers)
Selecting a breed fills in typical adult weight, length, and height — adjust if your dog runs big or small for the breed.
Units
Note: switching units does not convert numbers you already typed — pick your units first.
Step 1 — Weight
Step 2 — Body length
Step 3 — Height
Step 4 — Still growing?

How crate sizing actually works
A crate should be just big enough for your dog to stand up without crouching, turn around easily, and lie down stretched out — and no bigger. That is the entire rule. Everything else is arithmetic on top of it.
Measure length (nose to tail base) and height (floor to top of head), then add about 5 inches to the length and 4 inches to the height. Pick the smallest standard crate that covers both numbers. Weight is a sanity check, not the primary input — a 65-pound Greyhound is all legs and needs a taller crate than a 65-pound Bulldog.
Standard crate sizes at a glance
| Crate | Dimensions (L x W x H) | Typical dogs |
|---|---|---|
| 18" | 18 x 12 x 14 in | Teacup breeds, very small puppies |
| 24" | 24 x 18 x 21 in | Chihuahua, Yorkie, Maltese, Pomeranian, Pug, Shih Tzu, French Bulldog |
| 30" | 30 x 21 x 24 in | Beagle, Corgi, Cocker Spaniel, Miniature Dachshund |
| 36" | 36 x 24 x 27 in | Border Collie, Australian Shepherd, Husky, English Bulldog |
| 42" | 42 x 28 x 30 in | Labrador, Golden Retriever, German Shepherd, Boxer, Standard Poodle |
| 48" | 48 x 30 x 33 in | Rottweiler, Doberman, Greyhound — the largest standard size |
Giant breeds (Great Dane, Saint Bernard, Mastiff) often need a 54" XXL crate, usually ordered online. Dimensions vary slightly by brand — always check the maker's chart before buying.
Wire vs plastic vs soft-sided
Wire crates are the default home crate: great airflow, visibility, fold flat, and most include the divider panel puppies need. Downsides: not airline-approved and some dogs find them too exposed (a cover fixes that).
Plastic kennels feel den-like and secure, work for car travel, and many are airline-approved for cargo. Downsides: bulkier to store and less ventilation.
Soft-sided crates are light and packable — great for travel, camping, and calm crate-trained dogs. Not for chewers, escape artists, or dogs still learning the crate.
For a puppy, start with wire: it is the only type that reliably comes with a divider panel.
Puppy rule: buy once, divide
Buy the crate for your puppy's expected adult size and use the divider panel to keep the living space small while they grow. A crate that is too roomy slows potty training — if the puppy can toilet in one corner and sleep in the other, slide the divider in. Move it out a little every few weeks as they grow.
Frequently asked questions
How do I measure my dog for a crate?
Two measurements with a soft tape: length from the tip of the nose to the base of the tail (not the tail tip), and height from the floor to the top of the head while standing. Add about 5 inches to the length and 4 inches to the height, then choose the smallest standard crate (18" to 48") that covers both.
What size crate does my dog need?
It depends on body measurements, not weight alone. As rough guides: small breeds like Chihuahuas and French Bulldogs usually take a 24" crate, Beagles and Corgis a 30", Border Collies and Huskies a 36", Labradors and German Shepherds a 42", and Rottweilers and Dobermans a 48". Use the finder above with your dog's real numbers for an exact answer.
Should I buy a bigger crate for a puppy?
Buy the adult-size crate, not a bigger one — then use the included divider panel to shrink the space while your puppy grows. This saves buying two crates, and the snug space actually speeds up potty training.
Can a dog crate be too big?
Yes. An oversized crate can make a dog feel exposed rather than den-like, and it undermines potty training because the dog can toilet in one corner and sleep in the other. Between sizes, go one up — but don't jump two.
Wire vs plastic vs soft-sided crate — which is best?
Wire for home use (airflow, folds flat, divider included). Plastic for travel and airline cargo (den-like, sturdy). Soft-sided for calm, crate-trained dogs on trips. For puppies, wire wins because of the divider panel.
What size crate for a Labrador?
Most adult Labradors (55–80 lbs, about 24" tall) fit a 42" crate (42 x 28 x 30 in). Large males at the top of the breed standard occasionally need a 48" — measure your individual dog rather than going by the breed name.
