Dog Crate Size Calculator
=========================

Measure your dog and get a recommended crate length, height, width, and standard crate size. Includes a printable fit checklist.

Before you buy

- Measure from nose to base of tail, not to the tail tip.
- Measure sitting height to the top of the head or ears, whichever is higher.
- Compare internal crate dimensions, not only the product name.
- Use a divider for puppies when the adult-size crate is much larger than they need today.
- Check whether bedding or a crate pad reduces usable height.
- Confirm door size if the dog is tall, elderly, or reluctant to duck into a crate.
- Recheck fit after growth, weight change, injury, or a change in bedding.
- For travel, confirm airline, vehicle, or carrier rules separately.

When this estimate may be wrong

- Airline travel crates can have different requirements from home crates.
- Very broad-chested or long-backed dogs may need extra width or length.
- Dogs recovering from injury or with mobility issues may need advice beyond a simple size estimate.
- Retail crate names often use outside length, not internal usable length.
- Breed examples are only starting points; individual dogs vary within a breed.
- A crate that fits at home may not satisfy airline or transport rules.

Fit checklist

After choosing a likely size, check the internal dimensions from the specific manufacturer. External crate dimensions can be several inches larger than the usable internal space, and bedding, trays, sloped sides, or rounded corners can reduce the room your dog actually has.
