Countertops are quoted per square foot but measured in linear feet along the cabinets. A standard run is 25.5 inches deep, which includes the inch of overhang past the cabinet face.
How this is calculated
- Counter area = linear feet × depth ÷ 12. Standard depth is 25 to 25.5 inches including overhang.
- Backsplash is priced as additional square footage in the same material. Four inches is the standard height.
- Fabricators usually charge a minimum and bill edge profiles, cutouts for sinks and cooktops, and seams separately.
Frequently asked questions
How deep is a standard countertop?
Twenty-five to twenty-five and a half inches, which is a 24 inch cabinet plus about an inch and a half of overhang.
What is not in this estimate?
Fabrication, sink and cooktop cutouts, edge profile upgrades, seams, templating, delivery and installation. On stone, these can rival the material cost.
