Countertop depth most commonly falls in the range of about 24 to 25.5 inches (roughly 60 to 64 cm). The standard depth is typically 24 inches for the cabinet base plus a small overhang, which brings the total to about 25.5 inches. Islands and peninsula counters can be deeper, often around 27 to 30 inches or more, depending on layout and desired workspace. If you plan for seating or a bar area, a shallower or deeper profile may be chosen based on comfort and legroom. Key points to consider:

• Standard base cabinet depth: 24 inches (61 cm).
• Typical countertop depth: 25 to 25.5 inches (63.5 cm).
• Island/peninsula depths: commonly 27 to 36 inches (68.6 to 91.4 cm) depending on function.
• Overhang: many installations include a small overhang (about 1.25 to 1.5 inches) for edge protection and usability.

If you share your kitchen layout, preferred workzone flow, and whether you want seating at an island, the depth recommendation can be tailored to fit your space and ergonomic needs.
