The size of the stones blocks should be in proportion to wall thickness.
Stone masonry wall thickness.
Masonry is built from accurately dressed stones in uniform and fine joints of about 3 mm thickness by arranging the stone blocks in various patterns.

Decrease the stone thickness from the bottom to the top of wall.
The minimum thickness of wall in stone masonry can be 35 cm whereas in brick masonry walls of 10 cm thickness can be constructed.
Stones are arranged at random in random rubble masonry.
The minimum thickness for unreinforced masonry shear walls and for masonry foundation walls is also 8 in.
The minimum thickness of parapet wall can be assumed to be 203mm 8 inch and its height should not be larger than three times the wall thickness.
Random rubble masonry is the first variety of stone masonry.
The brick masonry construction proceeds very quickly whereas the stone masonry construction proceeds vary slowly as the bricks are handy whereas stones are not.
Ensure that the headers in the heart of the wall are the same size as in the face and extend at least 12 in 300 mm into the core or backing.
For buildings more than one story high walls must be at least 8 in.
