Crate size questions

How do I measure my pet for an IATA crate?

Take four measurements with your pet standing naturally: A (nose tip to base of tail), B (floor to elbow joint), C (widest point across shoulders), and D (floor to top of head or ear tips). Enter all four into the calculator to get your minimum crate size.

What is the IATA formula for minimum crate size?

Per IATA Live Animals Regulations Container Requirement 1: Minimum Length = A + B/2, Minimum Width = C x 2, Minimum Height = D (plus any bedding thickness). Snub-nosed breeds such as Bulldogs, Pugs, and Persians require all dimensions to be at least 10% larger.

Do airlines accept any IATA-sized crate?

Most airlines require a rigid, IATA-approved crate with ventilation on at least three sides, a leak-proof floor, and secure metal hardware. The IATA formula gives you the minimum internal dimensions. Always confirm the exact crate model and size with your airline before booking.

Does my snub-nosed dog need a larger crate?

Yes. IATA regulations require brachycephalic (snub-nosed) breeds such as French Bulldogs, English Bulldogs, Pugs, Shih Tzus, Boxers, and Persian cats to travel in a crate that is at least 10% larger in every dimension than the standard formula result. Use the snub-nosed option in the calculator to apply this automatically.

Based on IATA Live Animals Regulations Container Requirement 1. Always confirm crate size with your airline before travel.
