Crate Size Calculator
Measure your dog from nose to the base of the tail and from the floor to the top of the head while sitting. The calculator gives the crate size, the minimum inside length and height, and a rough weight guide.
- From length and height
- Standard crate sizes
- Puppy advice
Measure with the dog standing for length and sitting for height, including ears that stand up.
A crate should let your dog stand, turn and lie flat. Add about 3 inches to your dog's length and to its sitting height. A dog 33 inches long needs at least a 36 inch crate, the size for most Labradors and similar medium to large dogs.
