The two different sizes of the shapes represent proportions according to the clients perception.
The proportional importance of each person and/or issue represented in the spread may be shown by the different sizes, in addition to the shape and colour.
Equally sized mats can be interpreted as having/representing the same ‘value’.
For example, clients sometimes select large mats to represent problems, and use small mats to represent themselves … or they might pick small mats to represent a child or something ‘small’.
This additional option of size selection can also be omitted, with the client asked to choose from one set only i.e. only large or only small mats. If required, the other sized set can then be added later. There are many possibilities, depending on the preferences and instincts/intuition of the therapist.
