To create a scale factor for the Leaning Tower of Pisa, first measure the height of the tower, which is approximately 56 meters. Then, decide on a model size or a desired scale, such as 1:100. Divide the actual height by the model height to determine the scale factor; for example, if the model is 0.56 meters tall, the scale factor would be 100:1. This ratio can then be used to proportionally adjust other dimensions of the tower for your model.
