Dog Crate Size Chart: Find the Right Crate by Breed
A crate that's too small is uncomfortable; a crate that's too big defeats the purpose of housetraining. Getting the size right on the first try saves money (crates aren't cheap) and spares your dog weeks of either cramped confinement or midnight potty accidents.
This guide gives you the two-measurement sizing rule used by trainers and vets, a breed-by-breed reference chart, and practical advice for puppies, travel crates, and crate types. Follow it and you'll buy exactly one crate — the right one — instead of two.
The Sizing Rule: Two Simple Measurements
Forget "buy the biggest crate you can afford." Correct crate sizing comes from your dog's own dimensions:
- Length: body length + 15 cm. Measure from the tip of the nose to the base of the tail (not the tail itself), then add 15 cm (about 6 inches). That's the minimum interior crate length — enough room to lie stretched out and turn around, but not enough to create a separate "bathroom corner."
- Width: shoulder height × 1.5. Measure from the floor to the top of the shoulder (withers), then multiply by 1.5. That's the minimum interior width — enough space to stand, sit, and shift position without the shoulders or head brushing the sides. Add a further ~10 cm of height clearance so the dog can sit and stand upright comfortably.
Why these specific numbers? The +15 cm length buffer covers the space needed to turn around and stretch without giving a housetraining puppy surplus room to eliminate away from its sleeping spot. The 1.5× shoulder-height width factor accounts for the body room needed to turn, sit, and lie down without feeling boxed in.

How to Measure Your Dog Correctly
Accurate input, accurate crate. Three tips:
- Measure standing, on a flat surface, head in a natural position (not looking up at a treat).
- Body length excludes the tail. Tail length varies wildly between breeds and has nothing to do with lying-down space.
- For sit clearance, note the height when your dog sits — some breeds (upright-eared, tall-headed breeds like Dobermans) need extra height beyond the standard +10 cm clearance.
If your dog is between sizes or still has a growing frame, always size up on length rather than height — but see the puppy section below before buying the "adult size" immediately.
Dog Crate Size Chart by Breed
Standard crate sizes map to weight and measurement ranges. Use this as a starting point, then confirm with the two-measurement rule:
| Crate Length | Typical Dimensions (L×W×H) | Breeds That Fit |
|---|---|---|
| 24 in (60 cm) | 60×45×50 cm | Chihuahua, Yorkie, Pomeranian, Maltese |
| 30 in (75 cm) | 75×50×55 cm | French Bulldog, Pug, Shih Tzu, Mini Dachshund |
| 36 in (90 cm) | 90×60×65 cm | Beagle, Cocker Spaniel, Corgi, Shiba Inu |
| 42 in (105 cm) | 105×70×75 cm | Border Collie, Bulldog, Vizsla, Standard Schnauzer |
| 48 in (120 cm) | 120×75×80 cm | Labrador, Golden Retriever, German Shepherd, Boxer |
| 54 in (135 cm) | 135×85×90 cm | Rottweiler, Bernese Mountain Dog, large male GSD |
Two caveats:
- Proportion matters more than weight. A Border Collie and a Bulldog can weigh the same, but the Collie needs more length and the Bulldog more width and height.
- Airline crates use different rules (see the travel section below) — never assume a home crate meets airline requirements.
Puppies: Buy the Adult Crate, Use a Divider
This is the classic puppy mistake: buying a crate sized for the 8-week-old. It will be far too small within months, and you'll pay twice.
The correct approach:
- Buy the crate sized for the predicted adult measurements (breed standard for purebreds; for mixes, estimate adult size — our Puppy Weight Predictor gives you the adult weight to cross-reference against the chart above).
- Install the divider panel (most wire crates ship with one) to shrink the usable area to puppy size.
- Move the divider back every few weeks as the puppy grows, until it's removed entirely around 6–9 months.
Why bother with the divider at all? A puppy with more space than it needs will sleep in one corner and eliminate in the other — the exact opposite of what crate training is supposed to teach. The divider keeps the space "just big enough," which is the whole mechanism by which crates support housetraining.
Wire Crates vs. Plastic (Airline) Crates
| Feature | Wire Crate | Plastic (Airline) Crate |
|---|---|---|
| Ventilation | Excellent | Good (side vents) |
| Visibility | Open — some dogs love it, anxious dogs may prefer covered | Enclosed, den-like |
| Portability | Folds flat but heavy | Lighter, carry handle |
| Durability | Strong chewers can bend wires | Solid shell, hard to destroy |
| Airline travel | Not approved for cargo | Approved (check airline spec) |
| Cleaning | Tray slides out | Two halves separate |
| Best for | Home use, training, warm climates | Travel, den-loving dogs, vet visits |
Rule of thumb: wire crate for home, plastic crate for travel. If you only buy one and travel occasionally, a wire crate with a washable cover covers most home needs.
For air travel, airlines require the dog to stand, turn, and lie down naturally inside the carrier, with the ears not touching the top — measure before flying, and check your airline's exact requirements, since they vary.
Where to Place the Crate (It Matters More Than You Think)
- Living area first. Dogs are social; a crate in a lonely corner teaches the dog that the crate = isolation.
- Bedroom at night, especially for puppies — hearing you reduces nighttime anxiety and lets you hear potty signals.
- Away from radiators and direct sun, with a draft-free back corner.
- Never use the crate as punishment. The moment the crate becomes a penalty box, housetraining and calm crate behavior collapse together.
Common Crate Sizing Mistakes
- Sizing by weight alone. Weight ignores proportions; measure length and height instead.
- Buying "to grow into" without a divider. Too much space breaks housetraining (see puppy section).
- Ignoring sitting height. Sighthounds and erect-eared breeds frequently need one height size up.
- Forgetting door orientation. In tight apartments, check whether the crate's doors open the direction your space allows before buying.
- Assuming bigger is kinder. An oversized crate loses its den function; a properly sized crate feels like a bed, not a cage.
Frequently Asked Questions
What size crate for a Labrador? Usually 42 inches (105 cm) — measure your individual dog, since show-line Labs run larger. A male Lab at the top of the breed standard may need 48 inches.
Can I use a crate that's slightly too big? For a housetrained adult dog, slightly oversized is merely less cozy. For a puppy in training, excess space actively sabotages housetraining — use a divider.
How do I know the crate fits? Your dog can stand fully upright, turn around in one motion, and lie on its side with legs extended. If any of those fails, the crate is too small.
Should the crate have bedding? Yes for settled dogs — a thin mat, not a thick bed that eats the interior space (re-measure with bedding in place). Skip loose bedding for puppies that chew fabric.
What about double-door crates? A side door plus top/front door adds placement flexibility in small spaces. The sizing rule is identical.
How long can my dog stay in the crate? As a guideline: puppies can hold their bladder for roughly their age in months plus one, in hours — a 3-month-old puppy shouldn't be crated longer than about 4 hours during the day. Adult dogs can manage longer, but a full workday in a crate is too much for most; arrange a midday break. The crate is a rest space, not a lifestyle.
Should I buy a crate cover? A breathable cover can turn an open wire crate into a den for dogs that prefer enclosure — useful for anxious dogs and noisy environments. Skip the cover for dogs that pant or overheat easily, and never cover all sides so tightly that airflow stops.
Measure Once, Buy Once
The entire decision reduces to two numbers: body length + 15 cm, and shoulder height × 1.5. Every crate on the market that meets those two measurements is the right crate, regardless of brand or price.
