Even today, the retaining walls and their different types are still used and investigated. Conventional design methods and construction principles have been converting to the mechanically stabilized earth walls. This study performs to reveal footing width variation by changing the dimensions of different reinforced concrete (RC) cantilever walls within proportionality limits. These walls are differentiated as Tshaped RC cantilewer walls, stem-stepped RC walls and couter-fort walls. In loading laterally walls, the M-O method was used for calculating total active lateral pressure with/without earthquake motion and hydraulic pressure. At first, the stability analysis was applied to the initial dimensions of walls in the scope of experienced design parameters. After checking wall safety against sliding, overturning and bearing capacity failure, reinforcement process of wall components was conducted. Cross sections of concrete wall components and their steel reinforcements were checked by using TS500 specification. It is determined that the extreme loading required the greatest footing widths and otherwise, the smallest widths revealed without earthquake and hydraulic pressure. When considered all loading cases, it can be said that steem-stepped cantilever walls provided the most suitable wall dimensions satisfying conditions regarding stability analysis and reinforcement. This process is followed by counter-type cantilever wall as second one and finally by T-shaped cantilever wall.
