How to Choose the Right Dog Crate Size and Type for Your Breed (2026)

Measure height from the floor to the top of the head, or to the tips of the ears if your dog has upright ears like a German Shepherd. Add four inches to each measurement. That gives you the minimum interior dimensions your crate should provide. A dog should be able to stand without hunching, turn a full circle, and lie flat on its side with legs extended. If it cannot do all three, the crate is too small. Crates are typically sold in standard sizes ranging from 18 inches (extra small, suitable for toy breeds under 10 lbs) up to 54 inches (extra large, suited for giant breeds like Great Danes and Mastiffs). The most common sizing brackets look roughly like this: 24 inches for dogs up to 25 lbs, 30 inches for dogs up to 40 lbs, 36 inches for dogs up to 70 lbs, 42 inches for dogs up to 90 lbs, and 48 inches or larger for anything above that. These are interior length figures, so always cross-check against the product's listed interior dimensions rather than the model name alone — manufacturers are inconsistent about what they call 'large' versus 'extra large.' Breed weight charts are a useful starting point but not a substitute for measuring. Dogs of the same breed vary considerably. A lean, tall Labrador and a stocky, shorter one may both weigh 65 lbs but need different crate heights. Measure the individual animal, not the breed average.

They offer maximum airflow, which matters in warmer climates or for double-coated breeds. The open design lets your dog see the room, which reduces anxiety for social dogs. Most wire crates fold flat for storage or travel, and many include a divider panel — a feature that becomes critical when crate-training a puppy (more on that below). The trade-off is aesthetics and noise: wire crates are not subtle, and a dog that paws or rattles the door creates real noise. They are also heavier than soft-sided options. Soft-sided crates, typically made from nylon or polyester over a lightweight frame, are best suited to calm, already-crate-trained dogs and frequent travelers. They are genuinely portable — most collapse to a fraction of their open size and weigh just a few pounds. The downside is durability. A determined chewer or an anxious dog that scratches at the walls will destroy a soft crate quickly and could escape, which is a safety issue. Do not put a dog that has not been fully crate-trained into a soft-sided crate unsupervised. Furniture-style crates, sometimes called decorative or wooden crates, are designed to double as end tables or console tables. They solve the aesthetic problem completely and can blend into any room. Quality varies enormously. Well-built models with solid wood construction and secure latches are genuinely sturdy; cheaper versions with thin MDF panels are not. Ventilation is typically lower than wire crates, so they are better suited to short rest periods than extended stays. They are also the heaviest option and essentially impossible to travel with. For most dog owners, especially those with puppies or dogs still in training, a wire crate is the practical default. Soft-sided crates earn their place once training is complete and travel is a priority. Furniture-style crates make sense when the dog is fully settled and the owner wants the crate to disappear into the decor.

Push it into a corner or against a wall and you lose easy access. A double-door model gives you flexibility: put the front door against a wall and use the side door as the main entry, or position the crate so both doors are accessible and let your dog choose which end it prefers to enter from. Dogs that are anxious about enclosed spaces often settle faster when they can see an exit at both ends. For crate training specifically, the double-door setup is worth the modest price premium. You can feed meals through the side door while the front door is open, gradually closing it over multiple sessions. This lets you work the training from two angles and adapt to how your individual dog responds. Once training is complete and the dog is comfortable, the second door becomes less critical — but it never hurts. Top-opening crates are a niche option, mostly useful for small dogs that are easier to lift in and out, or for dogs that resist walking into a front-facing opening. They are less common and typically more expensive, but worth considering if your dog has a strong aversion to entering a crate head-first.

Most wire crates include a divider for exactly this reason. The principle is straightforward: a puppy should have just enough room to stand, turn around, and lie down — no more. If the crate is too large, the puppy will use the far end as a toilet, which undermines house training. The divider lets you expand the space incrementally as the puppy grows, reaching the full crate size when the dog reaches adult dimensions. To estimate adult size, ask your breeder or check the breed standard. For mixed breeds, a vet can give a reasonable estimate based on the puppy's current weight and paw size. As a rough guide, most puppies reach about half their adult weight by four months. If you have a 10 lb puppy at four months and the breed typically reaches 60 lbs, plan for a 42-inch crate. For toy breeds that will stay small — Chihuahuas, Yorkies, Toy Poodles — you can often buy the final adult size from the start without needing a divider, since the size difference between a toy puppy and a toy adult is small enough that a single appropriately-sized crate works throughout. One product worth mentioning for puppy crate training is the KONG Classic dog chew toy, which many trainers recommend placing inside the crate to give the puppy a positive association with the space. A stuffed KONG gives the puppy something to work on while confined, reducing whining and restlessness during the early training phase.

Physical signs like red marks on the nose or paws from pressing against the bars also indicate the dog is trying to create more space. A crate that is too large for an untrained dog presents the opposite problem — the dog treats part of it as a bathroom. But once a dog is fully house-trained, a larger crate is not harmful. Adult dogs that are fully trained and comfortable can use crates with considerably more room than the minimum, and many owners opt for a size up at that stage to give their dog more comfort during longer rest periods. Growth spurts in adolescent dogs (roughly six to eighteen months depending on breed) can make a previously adequate crate feel cramped quickly. Check the fit every couple of months during this period. If your dog was comfortable in a 36-inch crate at six months but is now a year old and showing signs of discomfort, measure again — the dog may have grown more than expected. For anxious dogs, a crate that is technically the right size may still feel stressful. In those cases, covering three sides of a wire crate with a blanket to create a den-like environment often helps more than changing the size. Products like the Thundershirt Classic anxiety jacket are also commonly used alongside crate training for dogs that show generalized anxiety — the compression effect can take the edge off during the initial adjustment period.

Get those four right and the specific model matters far less than the marketing around it suggests. When you are ready to compare specific crates, our pet supplies category page covers the options worth considering across wire, soft-sided, and furniture-style designs. You can browse the full selection at our pet supplies guide to find a crate that fits both your dog and your budget without wading through options that do not apply to your situation.
