The depth of steel studs used in commercial construction is determined by a combination of factors, including partition height, the gauge of the stud, the spacing of the studs, and the number of layers of gypsum board.

Partition height is crucial because taller partitions may require deeper studs to ensure adequate structural support and stability. The gauge of the stud also plays a significant role; heavier gauges can provide greater strength, allowing for different depth requirements. The spacing of the studs affects the load distribution and overall wall assembly integrity, which can influence the necessary depth of the studs. Lastly, the number of layers of gypsum board can contribute to the overall wall thickness and, consequently, to the required stud depth to achieve a flush finish and structural integrity.

By considering all these factors comprehensively, one can determine the most suitable stud depth for a specific commercial construction scenario, ensuring compliance with structural, acoustic, and fire performance requirements.
