Dog Crate Size Calculator
What size crate does your dog need? A crate should be just big enough to stand up, turn around, and lie down, and no bigger. Enter your dog's weight, or add a measured length for a more accurate result, to get the recommended crate size.

Weight bands are a guide. Tall, lean dogs often need a larger crate than stockier dogs of the same weight, so measuring is more reliable. Interior dimensions vary by brand.
How to Measure Your Dog for a Crate
Measure your dog standing naturally on all four paws for the most accurate fit.
- Length: Measure from the tip of the nose to the base of the tail (do not include the full tail, since it bends inside the crate). Add 2 to 4 inches for the minimum crate length.
- Height: Measure from the floor to the top of the head or the tip of the ears, whichever is taller. Add 2 to 4 inches for the minimum crate height.
Pick the smallest standard crate that meets both measurements. A crate that is too big can actually make housetraining harder, so more room is not better.
Sizing a Crate for a Puppy
The most cost-effective approach for a growing puppy is to buy a crate sized for their predicted adult size and use a divider panel to shrink the usable space to their current size. That gives just enough room to stand, turn around, and lie down, which supports housetraining by discouraging a puppy from using one end as a bathroom.
Move the divider back every 4 to 6 weeks as your puppy grows, then remove it entirely once they reach adult size. To estimate adult size, check our breed weight calculators.
FAQs
Frequently Asked Questions
What size crate does my dog need?
A dog crate should be just big enough for your dog to stand up, turn around, and lie down comfortably, and no bigger. As a rough guide by weight: up to 25 lbs uses a 24 inch crate, 26 to 40 lbs a 30 inch, 41 to 70 lbs a 36 inch, 71 to 90 lbs a 42 inch, and over 90 lbs a 48 inch or larger. Measuring your dog is more accurate than weight alone.
How do I measure my dog for a crate?
Measure your dog standing on all four paws. For length, measure from the tip of the nose to the base of the tail (not the full tail) and add 2 to 4 inches. For height, measure from the floor to the top of the head or ear tips, whichever is taller, and add 2 to 4 inches. Choose the smallest standard crate that meets both.
What size crate for a Labrador or Golden Retriever?
Most adult Labrador Retrievers and Golden Retrievers need a 42 inch (XL) crate. Larger males may be more comfortable in a 48 inch. German Shepherds usually take a 42 or 48 inch crate depending on size.
What size crate should I get for a puppy?
Buy a crate sized for your puppy's predicted adult size and use a divider panel to shrink the usable space to their current size. This gives just enough room to stand, turn, and lie down, which supports housetraining by discouraging soiling one end. Move the divider back every 4 to 6 weeks as they grow, then remove it at adult size.
Can a dog crate be too big?
Yes. A crate that is too large lets a dog use one end as a bathroom, which undermines housetraining, and can feel less secure. The goal is enough room to stand, turn around, and lie down, plus a couple of inches of clearance, not extra open space.
