Much has been said in various manuals and treatises about the combat of the short fencer against the tall fencer and also vice versa. These are considerations of note and need to be taken into account. What does not seem to appear all that often are considerations of teaching a shorter or taller student and how this may change the approach that the teacher might take. This is something which needs to be considered as this will affect how the individual will be effective with their weapon.
Being a taller person, actions are performed in a particular way, and tactics are appropriate to a particular method. These are not so much for a shorter person. Thus as a taller person who is teaching people who are shorter, these things need to be taken into account. This is vital otherwise we are teaching the shorter person simply that they will be less effective because they are shorter and cannot do what the taller people can do, and this does everyone concerned a disservice.
