The thickness of a retaining wall depends on its height, the type of material used, and the load it needs to support. As a general rule, for concrete retaining walls up to 1 meter (about 3 feet) high, a minimum thickness of 150-200 mm (6-8 inches) is recommended, increasing proportionally for taller walls. Always consult a structural engineer for specific requirements based on site conditions.
