IATA Pet Crate Requirements: The Full Checklist
IATA publishes the container requirements that airlines following IATA rules use for dogs and cats travelling in the hold. Here is every rule in plain English, with the official source.

1. Size: the IATA formula
Length = A + ½ B (A = nose tip to root of tail; B = floor to elbow joint)
Width = C × 2 (C = width across shoulders or widest point). 2 animals: C × 3. 3 animals: C × 4.
Height = D + bedding (D = standing height, top of head or ear tip)
Snub-nosed breeds: the container must be 10% larger.
These are internal dimensions. Use the free calculator to work them out.
2. Fasteners: bolts, not clips only
The top and bottom halves of a plastic container must be bolted together. Plastic clips alone are not sufficient. Metal bolts are recommended in every hole.
3. Ventilation on all four sides
Ventilation openings are required on all four sides, with a total ventilated area of at least 16% of the surface of the four sides. Openings on the sides and back are placed over the upper two-thirds of the container.
4. Door, bowls, wheels, floor, labels
