Dog Crate Size Calculator
Enter your dog's measurements, weight, or both. You'll get the crate length to buy, the minimum inside height, and crates in that size.
36-inch crate
Puppy tip: buy this adult size now and use a divider panel so the space is just big enough to stand, turn and lie down. Move it back as your puppy grows.
Crates in this size
Always check the listing's inside dimensions — they're smaller than the outside size.
How the calculator works
From measurements, it adds 2–4 inches to your dog's length and height — the standard rule so your dog can stand without ducking, turn around and lie stretched out — then picks the smallest common crate size (18, 22, 24, 30, 36, 42, 48 or 54 in) that fits. From weight, it uses the typical ranges in manufacturers' sizing charts. If you enter both, it takes the larger answer.
For a full sizing chart by breed, crate types (wire, plastic, heavy-duty, soft) and our picks, read the dog crate size guide. Bringing home a puppy? See the new puppy checklist.
