Crate measurements
How to measure your dog for a crate
Measure length, sitting height, and shoulder width before comparing crate sizes.
A simple measuring guide for dog crate length, height, and width so the calculator result is based on usable internal space.
The three measurements that matter
The calculator uses body length, sitting height, and shoulder width because a crate must work for standing, turning, and lying down.
- Length: nose to the base of the tail.
- Height: floor to the top of the head or ears while sitting.
- Width: shoulder width at the broadest comfortable point.
Use internal dimensions
Retail crate names often refer to a standard outside length. Check the product's internal usable dimensions before deciding.
- Doors, rounded corners, trays, and frame thickness can reduce usable space.
- If the dog is between sizes, compare the next standard size and use the fit checklist.
- For puppies, adult sizing can work with a divider while training.
Measurement checklist
| Measurement | Where to measure | Common mistake |
|---|---|---|
| Length | Nose to base of tail | Including the full tail. |
| Sitting height | Floor to head or ears | Measuring only shoulder height. |
| Shoulder width | Broadest shoulder point | Using collar width instead of body width. |
