Tibetan iconography known as tig tse in Tibetan is the sacred geometry of Tibet.

Different classes of figures are are divided into groups, each group has its own special measurements. Since all of Buddhism comes from the Buddha he is the largest measurement.

Terms of units of measure in the Tibetan system:

1. 12 sor = 1 cha chen ( large measure),  shal gang (face measure),orthal. mo. Three names for the same consept. This is the measure of the face and the key to the iconography.

2. 1 sor - cha chung ( small measure) know as the finger width. A sor can be any size, so making any size image is possible. Then if a sor is 1 inch, a shal becomes 1 foot.

3. There are smaller measures but we will focus on these for now

 Generally these measurements are used in constructing the figure in any size.
