Dog Crate Size Calculator
What size crate does your dog need? This free dog crate size calculator finds the right crate by measurement, by breed and by weight — in inches or cm — matches it to a standard 24″ to 54″ crate, works out an IATA travel kennel for flying, and shows how to size a puppy crate with a divider.
How the Dog Crate Size Calculator Works
Weight and breed are fast shortcuts, but the measurement method is the most reliable because two dogs of the same weight can have very different body shapes and leg lengths.

How to Measure Your Dog for a Crate
Getting the measurements right takes two numbers and a tape measure. For length, measure from the tip of the nose to the base of the tail (not the tip of the tail — that would make the crate too long). For height, measure from the floor to the top of the head while your dog is sitting; for tall, erect-eared breeds, measure to the ear tips. Then add 2 to 4 inches to each figure so your dog can stand and turn in comfort, and match the result to the nearest standard size. A crate that is correctly sized feels snug but not cramped — a den, not a kennel run.
What Size Crate for a Puppy?
For a puppy, buy the crate that fits their expected adult size and use a divider panel to wall off the extra space while they are small. This saves buying two or three crates as they grow. The reason you don’t simply give a puppy a big crate is house-training: dogs instinctively avoid soiling where they sleep, but if the crate is large enough to have a separate “bathroom” corner, that instinct breaks down. Give the puppy just enough room to stand, turn and lie down, and slide the divider back as they grow. Most wire crates include a divider in the box.
What Size Crate Do I Need for Air Travel?
Flying is the one case where the everyday “stand and turn” rule is written into a formal standard. The IATA Live Animals Regulations set the minimum travel-kennel size with four body measurements: A (length from the nose or front-toe tip to the base of the tail), B (height of the front leg from the floor to the elbow), C (width across the shoulders), and D (height from the floor to the top of the head or ear tips while standing). The kennel must be at least A + ½B long, C × 2 wide, and D tall. Your dog must be able to stand fully upright without the head touching the roof, turn around, and lie down naturally. Airlines round up to a stocked kennel size, and some carriers add their own margins, so always confirm the exact requirement with your airline before booking. Air-travel kennels are rigid, IATA-approved carriers — not the collapsible wire crates used at home.
