Leonberger crate size
An adult Leonberger at 120–170 lb is heavier than the largest band in the manufacturer's chart (110 lb), so the answer is a 54 in crate and a tape measure rather than a chart row.

Which crate for a Leonberger
The chart below is MidWest's iCrate sizing, the most common wire crate in US pet stores, with the Leonberger's weight range marked. Interior lengths are the figures the manufacturer lists, not the nominal size, which is why a "36 in" crate is 36.6 in inside.
| Crate | Label | Interior L × W × H (in) | Dog weight | Leonberger |
|---|---|---|---|---|
| 18 in | Toy | 17.68 × 11.7 × 14.22 | 1–6 lb | Too small |
| 22 in | Extra Small | 22.5 × 14 × 16 | 7–12 lb | Too small |
| 24 in | Small | 23.6 × 16.7 × 19.1 | 11–25 lb | Too small |
| 30 in | Medium | 29.7 × 18.6 × 21 | 26–40 lb | Too small |
| 36 in | Intermediate | 36.6 × 21.9 × 24.5 | 41–70 lb | Too small |
| 42 in | Large | 41.9 × 29.5 × 30.3 | 70–90 lb | Too small |
| 48 in | Extra Large | 47.76 × 29.6 × 31.7 | 90–110 lb | Too small |

Measure before you buy
Weight bands are a shortcut. The dimension that decides whether a crate works is body length. Stand the dog, measure from the tip of the nose to the base of the tail (not the tail tip), and add 2 to 4 inches; the crate's interior length must be at least that. For height, measure from the floor to the top of the head while sitting and add the same allowance.
The welfare rule is the one every shelter and trainer repeats: the crate must be large enough for the dog to stand up and turn around. Bigger is not better for house-training, because a crate with spare floor space invites the puppy to soil one end and sleep in the other, which is why the adult-size crates in this chart ship with a divider panel.
Puppies: buy the adult size and use the divider
A Leonberger puppy reaches 170 lb at maturity, so buying a puppy-sized crate means buying twice. Choose the crate for the adult weight above, fit the divider so the puppy has room to stand, turn and lie down and no more, and move the divider back as the dog grows. The Leonberger puppy feeding chart shows the growth stages the divider will follow.
Bed size for a Leonberger
Using Orvis's rectangle-bed fit guide, a 170 lb Leonberger takes the X-Large (53 × 35 in). Dogs that sleep stretched out need the length of their body plus a few inches; curl-sleepers can go one size down in a bolster bed. Full chart on the bed size page.
How the Leonberger compares
By mid-range adult weight, the Leonberger ranks 128 of 132 breeds on this site, with 4 heavier and 127 lighter — a giant breed in the size classes used here. In the AKC's 2024 registration ranking the Leonberger stood at number 99. The standard separates the sexes: females top out around 35 lb lighter at 100–135 lb and stand 25½–29½ in, which is why a female often fits the smaller of two candidate crates. AKC's preferred heights are 30 in for males and 27½ in for females.
Breeds of similar weight, whose crate answer is the same or one size off: Great Dane (110–180 lb), Great Pyrenees (120–165 lb), Neapolitan Mastiff (about 150 lb), Newfoundland (143–176 lb), Saint Bernard (120–200 lb).
Adult height from AKC breed standard (PDF); adult weight from Wikipedia breed infobox/body; both checked 2026-10-21. The AKC standard states the height but not the weight, so the weight here is from Wikipedia breed infobox/body. Height is at the withers in inches; weight in pounds for adult dogs. Where a breed standard states a figure it is used first (AKC, then FCI); where the standard is silent, the Wikipedia infobox or VCA breed page is used and named. Metric figures were converted and rounded to the nearest half inch or pound. Where the source gives only a maximum, the range reads "up to" that figure.
