How to Choose a Dog Crate Size

Crate size is the #1 thing people get wrong. Too small is cruel; too big undermines house-training. Here’s the simple method.

Measure your dog

Measure length (nose to base of tail) and height (floor to top of head when sitting). Add about 2–4 inches to each. That’s your minimum crate size.

Crate types

• Wire — best ventilation, folds flat, includes a divider (great for puppies).
• Plastic — cozier, travel/airline-friendly.
• Soft-sided — light and portable, for calm, trained dogs only.

Training a puppy? Buy the adult size and use the divider to shrink it as they grow.

Frequently asked questions

What size crate does my dog need?

Measure your dog’s length and sitting height and add 2–4 inches to each. The crate should let them stand, turn around, and lie down fully — and no bigger.

Should I size up the crate for a puppy?

Buy the adult-size crate and use a divider to section off a smaller area. Too much room lets a puppy potty in one corner and sleep in another, which slows house-training.

Wire or plastic dog crate?

Wire crates ventilate best, fold flat, and usually include a divider — ideal at home. Plastic crates are cozier and better for car and air travel.
