Dog Crate Size Calculator — Pick the Right Crate by Weight or Measurement
What size crate fits your pup? This calculator gives a quick estimate from weight alone or a precise size from physical measurements — applying the standard length + 4 inches and height + 4 inches rule recommended by the American Kennel Club crate-size guide. Sizes match the standard 22, 24, 30, 36, 42 and 48-inch retail crates. For puppies, buy the adult size with a divider panel — you only need one crate over the lifetime.

Frequently Asked Questions
What size crate do I need for my dog?
Measure your dog's length (nose to tail base) and height (standing). Add 4 inches to both — the crate should be at least that size. Or use the standard size-by-weight guide: XS/22" under 12 lb, S/24" 13–25 lb, M/30" 26–40 lb, L/36" 41–70 lb, XL/42" 71–90 lb, XXL/48" over 90 lb.
Can a crate be too big?
Yes — especially for house-training puppies. Dogs naturally avoid soiling their sleep area, but if the crate is large enough to have a 'bathroom corner,' they'll use it. Use a crate divider for puppies and remove it as they grow.
What size crate for a Labrador Retriever?
A fully-grown Labrador (55–80 lb) needs a 42-inch (XL) crate. Use 36-inch (L) for smaller females and growing puppies, and upgrade when weight reaches 60+ lb.
What size crate for a French Bulldog?
Most Frenchies (16–28 lb) fit comfortably in a 24-inch (S) or 30-inch (M) crate. Adults often prefer the larger option for stretching out.
How big should a crate be for a puppy?
Buy the adult size with a removable divider. Partition off just enough for the puppy to stand, turn and lie down. Expand every few weeks as they grow.
Should I get a wire or plastic crate?
Wire crates offer better ventilation and visibility; great for home use. Plastic airline-style crates (IATA-approved) are required for air travel and often feel more den-like for anxious dogs. Soft-sided crates are only for calm, trained adults.
