Yes, there are several physical requirements to become a flight attendant, though they are primarily focused on safety and functional ability rather than "appearance." The most common requirement is a minimum and maximum height, which is designed to ensure you can reach the emergency equipment in the overhead bins while also being able to fit through the emergency exits without obstruction. Most airlines require a height between 5'0" and 6'3". Additionally, you must be able to perform a "functional reach" (often 208cm to 212cm) to ensure you can secure cabin doors and reach oxygen masks. You must also be physically fit enough to handle the "heavy lifting" associated with opening massive aircraft doors and moving heavy food carts. For safety reasons, you must be able to fit into a standard "jumpseat" and use a seatbelt extender without it interfering with your ability to perform emergency duties. Other requirements often include the ability to swim a certain distance (usually 50 meters) without assistance, pass a drug test, and have no visible tattoos or piercings that cannot be covered by a standard uniform. Finally, you must have good vision (corrected or uncorrected) and the hearing ability required to hear alarms and communicate clearly during an emergency evacuation.
