How to measure for the right size shipping crate for your pet
According to IATA (International Air Transport Association) regulations, the size of a dog crate must allow for the animal to stand upright inside it without its ears or head touching the ceiling. The animal must also have room to turn around inside the cage, and must be able to lie down in a natural and comfortable position.
The right length (A + 1/2B): Measure the length of the animal from the nose to the base of the tail, and add half of the length of its front leg.
The right width (C x 2): Measure the width from shoulder blade to shoulder blade, and multiply by 2.
The right height (D): Measure the height of the animal from the paws to the tips of the ears.
