Mathematics plays a vital role in architecture, especially through concepts like scale and proportion. Ancient texts use the terms ḥiyal cadadi (numerical mechanic science) and ḥiyal handasi (geometrical mechanic science) for the application of number and measurement in craftsmanship. While ḥiyal handasi has been well studied, ḥiyal cadadi remains less explored. This study investigates numerical patterns in Timurid architecture, focusing on measurement systems and manuscript analysis. The mausoleum of Khwaja Ahmad Yasawi is the primary case due to its historical importance, serving as a basis for analysing dome space plans of other selected buildings. Due to limited sources, the research relies solely on written manuscripts and dome plans. Findings reveal a consistent structural sequence based on the smallest unit of 3 Gaz, with main dome spaces built on multiples of 6 Gaz.
