Saint Bernard crate size
An adult Saint Bernard at 120–200 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 Saint Bernard
The chart below is MidWest's iCrate sizing, the most common wire crate in US pet stores, with the Saint Bernard'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 | Saint Bernard |
|---|---|---|---|---|
| 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 Saint Bernard puppy reaches 200 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 Saint Bernard puppy feeding chart shows the growth stages the divider will follow.
Bed size for a Saint Bernard
Using Orvis's rectangle-bed fit guide, a 200 lb Saint Bernard 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.

Adult height from Wikipedia breed infobox/body; adult weight from VCA Animal Hospitals breed page; both checked 2026-10-20. 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.
