XL Dog Kennel Size Chart: How to Choose the Right Dimensions for Extra Large Dogs

For most US wire crates, XL means roughly 48 × 30 × 32–33 inches, built for dogs near 90–110 lb — but the label varies by brand, so measure your dog first.

For the full breakdown, see our best XL Dog Kennel guide.

A tape measure settles the question faster than any weight chart. “XL” is not a legal category — it’s a manufacturer’s marketing label, and one brand’s XL is another brand’s large. A crate that fits a 100-pound Labrador can be too short for a lanky Greyhound of the same weight, because body proportions matter more than the scale. Measuring body length and standing height, then adding a few inches, gets you a kennel the dog can stand in, turn in, and stretch out in.

What Size Is An XL Dog Kennel In Inches?

An XL wire crate in the US market typically measures about 48 inches long, 30 inches wide, and 32 to 33 inches tall. MidWest lists its iCrate XL at 48 × 30 × 33 inches and sells a bigger XXL at 54 × 37 × 45 inches, so even one brand’s size ladder steps past XL.

Retail charts disagree on what the label covers. PetSmart’s sizing chart lists “Extra large” at 36 inches long by 28 inches high for dogs 90 lb and up — shorter than most 48-inch XL crates and a clear sign the category is not standardized.

Petmate’s plastic Vari Kennel line runs on its own numbering. The 40-inch model, recommended for 70–90 lb dogs, measures 40 × 27 × 30 inches. Petmate’s Giant Vari Kennel jumps to 48 × 32 × 35 inches and is built for pets up to 34 inches tall, naming Great Danes, Greyhounds, Newfoundlands, Saint Bernards, and Bullmastiffs.

XL Dog Kennel Dimensions By Category

Match the crate to the dog’s measured length and height, not to a breed name or a weight range alone. The table below compresses the common US sizing bands into one reference.

These are general bands, not fit guarantees, and the interior of a crate is always smaller than its exterior. Petmate publishes separate interior measurements for its kennels — read those before you commit, because a 48-inch crate does not offer 48 inches of usable floor.

Shopping for a specific model rather than a general size? A tested lineup of large crates with real-world fit notes is worth a look before you buy.

How Do You Measure A Dog For An XL Kennel?

Measure the dog from nose to the base of the tail, then measure standing height from the floor to the top of the head — ear tips included if the ears stand erect. Petmate’s sizing guidance calls for a kennel roughly 3 to 4 inches longer and taller than those two numbers.

Run the checks in this order and you won’t buy twice:

1. Length: nose to tail base, then add 3–4 inches.
2. Height: floor to head top or ear tips while standing, then add 3–4 inches.
3. Stand test: the dog must stand without crouching.
4. Turn test: the dog must turn around without pressing against the walls.
5. Lie test: the dog must stretch out flat, not curl to fit.
6. Deduct for gear: subtract bedding, mats, bowls, dividers, and the door opening.

Compare your numbers against the manufacturer’s interior dimensions, not the exterior footprint. A bed two inches thick eats two inches of height on a crate that was already close.

What Do Extra Large Dog Owners Get Wrong?

Weight-only shopping is the most common miss. Two 90-pound dogs can differ by six inches of body length, and a giant-breed puppy grows out of a crate fast.

Buying far too big for a puppy backfires on house-training — the dog may use one end as a toilet. A divider solves this: MidWest’s iCrate XL ships with one. Check floor-pan fit, latch security, door clearance, and ventilation too; a heavy giant breed may need a heavy-duty build instead of standard wire.

Kennel rules for air travel are separate from indoor fit. Measure to the dog, check the specific airline’s dimensional and ventilation requirements, and treat the crate as confinement for rest and safety — never as a substitute for exercise, supervision, or temperature control.
