Each person who installs a pull-up bar will be of different heights. When it comes to knowing how high up to install your pull up bar the rule of thumb is to have it high up enough for you to be able to stretch your arms upwards to reach it. Some people like to be able to even jump upwards to be able to grab their pull up bar which is no problem and others would like to have it where they can reach their hands up to be able to grab it at their fingertips. The most average height to install your pull up bar is 60 inches from the floor.
