The Architect's scale

There are six sides with two scales on each side except the sixth side which is a ruler

3/32" = 1'-0" 3/16" = 1'-0"

1/8" = 1'-0" ?" = 1'-0"

?" = 1'-0" 1" = 1'-0"

3/8" = 1'-0" ?" = 1'-0"

1 ?" = 1'-0" 3" = 1'-0" (also called "quarter size")

On the sixth side is not a scale but a "ruler" which can measure things full size ? it is marked with a "16" because each inch is divided into 16 divisions or 1/16" spacing
