Puppy?
Size for the adult and use a divider. A crate bought to fit a puppy is outgrown in weeks, and a crate with a spare end stops working as a den. Buy the adult size and move the divider back as the dog grows. A harness or collar is the opposite: buy for the dog you have now, because adult-sized straps slip on a puppy.
Is your dog a mix?
Mixes vary a lot. Measure your dog. A breed figure describes a published standard, and a mix is not held to one. Two dogs from the same litter can land two sizes apart on the same chart.
Measure your Great Dane
The tables above start from a published breed range. This starts from your dog. Crates need a body length and a standing height, plus 4 in of room.
Size your Great Dane
Enter what you have measured. Every answer below is the maker’s own published range against your number — a starting point, not a fitting.
Published range for the Great Dane: 36 to 44 in chest, 22 to 28 in neck (Hund & Shore, "Dog Collar & Harness Size Chart by Breed").
Measure your dog and enter it. A published range is a range: the boxes below stay empty because the middle of a range is a number nobody published. Full Great Dane size chart

Common questions
- What size harness for a Great Dane?
- On the charts published by their makers, a Great Dane comes out at Julius-K9 IDC Powerharness 2 to 4 (3 sizes), Ruffwear Front Range Harness L/XL, Ruffwear Flagline Harness L/XL (by published chest girth), with 15 of 19 charts giving a size. Size labels are not comparable between brands, so read the range rather than the letter. Measure your dog's chest girth at the widest part of the rib cage and check it against the maker's own chart before you buy.
- What size crate for a Great Dane?
- By the makers' own weight guidance, a Great Dane comes out at no maker's weight guidance covers this breed, so measure instead. Weight is the rougher route: a crate is sized on the body. Measure your dog from the nose to the base of the tail and from the floor to the top of the head while standing, add 4 inches to each, and compare that with the crate's interior, not its outside.
- How big does a Great Dane get?
- An adult Great Dane is 30–32 in tall at the shoulder for males and 28–30 in for females, 140–175 lb for males and 110–140 lb for females. Published sizing charts give a chest girth of 36–44 in and a neck of 22–28 in. These are breed-standard ranges, not your dog: individual dogs sit outside them. Measure your dog.
