How tall you have to be to be a firefighter?

Answer 1

There is no height limit, although you may be limited to physical ability. Physical ability is important as a firefighter, so if you are limited then you probably do not want to become an interior firefighter.

There are still many jobs on a fire scene than entering a burning building, and they play a big role on scenes; So you can always look into doing support, being a driver, pump operator, Incident command, First Responder, etc. if you believe that you cannot do structural firefighting due to your height or limitations.

Answer 2

must departments dont have height requirements anymore. They usually have a "height proportionate to weight" requirement
