Generally, female flight attendants need to be at least 5 feet 3 inches to 6 feet 3 inches in height and weigh 58-70kg. Male flight attendants need to be 5 feet 7 inches to 6 feet 3 inches in height and weigh 68-82kg.

In the modern aviation industry of 2026, airlines have largely moved away from "fixed" weight requirements in favor of a Body Mass Index (BMI) standard and a "proportionate" appearance. For most major international carriers, the ideal weight for a female cabin crew member is typically defined as a BMI between 18.5 and 22 (or up to 25). This range ensures that the crew member is healthy and physically capable of performing demanding safety duties, such as operating heavy exit doors or providing medical assistance. Beyond the BMI, the most critical physical requirement is the "reach test," where a candidate must be able to reach a height of roughly 210–212 cm (6'11") while standing on tiptoes. This ensures they can access emergency equipment in overhead bins. While some regional airlines still maintain stricter aesthetic guidelines, the global trend focuses on fitness, agility, and a well-groomed professional appearance rather than a specific number on a scale, recognizing that "ideal weight" varies significantly based on an individual's height and muscle mass.
