Dog Crate Size Guide: What Size Crate Does Your Dog Need?
A crate that's too small is uncomfortable and unfair. A crate that's too big quietly sabotages house training — dogs avoid soiling their sleeping area, but give a puppy a mansion and they'll happily use the far corner as a bathroom. Getting the size right matters more than any other crate feature.
How to measure your dog (the right way)
- Length: Measure from the tip of the nose to the base of the tail (not the tail tip). Add 2–4 inches.
- Height: Measure from the floor to the top of the head, or to ear tips for erect-eared breeds, while sitting — dogs sit taller than they stand. Add 2–4 inches.
Your dog should be able to stand without crouching, turn around fully, and lie down stretched on their side. More room than that is unnecessary — dogs feel safer in dens, not halls.
Crate size chart by weight and breed
| Crate size | Dog weight | Example breeds |
|---|---|---|
| 18–22" (XS) | Under 10 lbs | Chihuahua, Yorkie, toy breeds |
| 24" (S) | 10–25 lbs | Pug, Shih Tzu, Mini Dachshund |
| 30" (M) | 25–40 lbs | Beagle, Cocker Spaniel, French Bulldog |
| 36" (L) | 40–70 lbs | Border Collie, Bulldog, smaller Labs |
| 42" (XL) | 70–90 lbs | Labrador, Golden Retriever, German Shepherd |
| 48"+ (XXL) | 90+ lbs | Rottweiler, Great Dane, Mastiff |
Always confirm against your own measurements — weight ranges are a starting point, and tall lean breeds (like Greyhounds) need more height than their weight suggests.
Buying for a puppy? Use a divider, not a small crate
Don't buy a puppy-sized crate you'll replace in four months. Buy the crate your dog will need fully grown (look up the breed's adult size), and choose one that comes with a divider panel. The divider shrinks the usable space while your puppy is small — keeping house training on track — and moves back as they grow.
The mistakes first-time owners make
- Sizing up "to be nice." Extra space doesn't feel generous to a dog; it feels less secure, and it undermines potty training.
- Ignoring door direction and placement. Measure where the crate will live. A 48" crate is furniture-sized.
- Buying plastic for a chewer. Determined chewers need heavy-gauge wire crates; plastic travel kennels won't survive.
- Using the crate as punishment. The crate must stay a safe, positive den, or your dog will fight going in — at exactly the moments you need it most.
Frequently asked questions
How long can a dog stay in a crate?
Adult dogs: up to 4–6 hours during the day at most. Puppies: roughly their age in months plus one, in hours (a 3-month puppy ≈ 4 hours max). Overnight is different — sleeping dogs comfortably crate for 7–8 hours.
Should I put a bed inside the crate?
Yes, once your dog is past the chewing-everything phase. A properly sized crate pad or an orthopedic bed for seniors makes the crate a genuine den. See our orthopedic dog bed guide.
Wire crate or plastic kennel?
Wire for home use (airflow, visibility, divider compatibility, folds flat). Plastic for car and air travel — it's the type airlines require.
