Standard countertops are typically 24 to 25.5 inches deep.
Standard Countertop Depth Explained
Based on common kitchen and bathroom designs, the standard depth for countertops ranges from 24 to 25.5 inches. This measurement is typically taken from the wall to the front edge of the countertop or, in the case of kitchen islands, from one finished edge to the other.
Cabinet Depth vs. Countertop Depth
The distinction in depth comes primarily from the base cabinetry they sit upon and the standard overhang.
- Most countertop boxes (referring to the standard base cabinets) measure 24 inches in depth.
- To provide clearance for doors and drawers and offer a comfortable edge, the countertop material extends beyond the cabinet face.
- A common standard is an overhang of an inch and a half (1.5 inches).
Adding this standard 1.5-inch overhang to the 24-inch cabinet depth results in the overall, finished depth of the countertop being 25.5 inches.
This depth is consistent whether the countertop is installed along a wall or forms an island, where the measurement is taken from edge-to-edge.
| Component | Standard Depth (Inches) |
|---|---|
| Base Cabinet Box | 24 |
| Standard Overhang | 1.5 |
| Total Countertop Depth | 25.5 |
